INTRODUCTION 1.1 History Instituto de Telecomunicações (it) is a private, not-for-profit organisation, an association of six institutions with experience and traditions in research and development in the field of Telecommunications: • Instituto Superior Técnico (IST); • Universidade de Aveiro (UA); • Faculdade de Ciências e Tecnologia da Universidade de Coimbra (FCTUC); • Portugal Telecom Inovação, (PTIn) • Nokia Siemens Networks S.A • Universidade da Beira Interior (UBI). it is organised around three sites: one in Aveiro, in the University Campus, another in Coimbra, in Site II of the University of Coimbra and the third one in Lisbon, in Instituto Superior Técnico. In addition there are four delegations: • Porto, shared by the Faculty of Engineering and the Faculty of Sciences of the University of Porto, • Leiria, in the “Escola Superior de Tecnologia e Gestão” of the Leiria Polytechnic (IPL), • Lisboa, in Instituto Superior de Ciências do Trabalho e da Empresa (ISCTE) • Covilhã, in the University of Beira Interior. Setting up of it was the result of a 1.5 billion escudos (about 7.5 million Euros) grant from Programme CIENCIA, through three contracts signed in 1991. This investment enabled new infrastructures to be built and research laboratories to be equipped at each site. Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994. Since 1993, it activities proceed regularly. it statutes were first approved in 1992, modified in 1997 and modified again in 2003. New site statutes deriving from it statutes were approved and implemented in 2005. 7 ANNUAL REPORT 2009- INTRODUCTION Key developments in 2009 are highlighted ahead. Details are included in the sections dealing with each of the research areas. 1.2 Management it is managed by a Board of Directors, elected by the General Assembly, and by Site Management Boards, which include the site members of the Board of Directors. Site Management Boards enjoy ample freedom to deal with current affairs and usually meet weekly. The Board of Directors meets at least once a month. it scientific activities are overseen by the Scientific Board, which includes all it researchers holding a Ph.D. degree. The Scientific Board meets in Plenary or in Committees, both permanent and temporary. There are two permanent committees: the Science and Technology Committee and the Research Group Coordination Committee. it Work Plan and the Annual Report are discussed with the Advisory Committee, formed by three independent experts in the field of telecommunications (Dr. Roland Huber, Prof. Sir John O’Reilly and Prof. Martin Tomlinson) acting in a personal capacity, and together with the Accounts (after legal certification) are subsequently submitted to the General Assembly for approval. The General Assembly met formally twice in 2009. The first meeting was held on March 30, in the Meeting Room of the Coimbra site, to discuss and approve the 2008 Annual Report and Accounts and to elect a new board of directors for the 2009—2011 period. The second meeting took place on December 16, in the Meeting Room of the Lisbon site, to approve the Work Plan and Budget for 2010, to discuss and approve the statutory change of the external laboratory of Porto and to discuss the request of LaSIGE to merge with it. The new board of directors is formed by: • Prof. Carlos Eduardo do Rego da Costa Salema, on behalf of IST; • Prof. Carlos António Cardoso Fernandes, on behalf of IST; • Prof. José Carlos da Silva Neves, on behalf of UA; 8 ANNUAL REPORT 2009 - INTRODUCTION • Prof. Henrique José Almeida da Silva, on behalf of FCTUC • Dr. José Marcelino Pousa, on behalf of PTIn. The Research Group Coordination Committee also met twice during 2009. On the first meeting, held on March 18, at the Aveiro site auditory, the Draft Proposal of the 2008 Annual Report, was discussed and received a favourable opinion. Scientific productivity was debated and the document “A policy for quality” was approved. On the second meeting, held on December 9, in the meeting room of Lezíria Parque Hotel (Vila Franca de Xira), the Work Plan and Budget for 2010, was discussed and received a favourable opinion and the request from LaSIGE to merge it was debated at length. Highlights of 2009 1.3 Like 2008, for many reasons 2009 was again a very good year for it. Firstly, the scientific output reached a new peak: • 67 books and book chapters; • 198 papers in international refereed scientific journals; • 16 patent requests; • 519 papers in refereed conferences, with published proceedings. Secondly, fostering of advanced education also reached a new peak: • 22 PhD theses, submitted and approved; • 194 MSc theses, submitted and approved. Thirdly, another it researcher (the third one) was elevated to the rank of IEEE fellow. Funding was, again, plentiful and timely. In particular • FCT finally paid back 1.09 M€ from the IT – Laboratório Associado contract, that it had paid (in advance) and had already been audited • FCT paid the basic fee (5.5 k€ per integrated researcher with PhD) 9 ANNUAL REPORT 2009- INTRODUCTION • FCT paid 60 % of the programmatic grant of 2009 (the reduction is due to FCT decision that post-doc salaries should be paid from the programmatic grant but were paid by FCT in the 2007-2009 period) • FCT paid the remaining dues of the 2004 projects Due to prior delays in the transfer of funds from FCT, the execution periods for the 2007 and 2008 were extended to the 31st of December 2009. Total funding for the two year period was 5.2 M€ and the execution rate (not yet audited) was 98 %. Thanks to available funding most labs (Optical Communications, Radio and Microwave, Instrumentation and Measurements, Power Electronics, Materials) in Lisbon (Media Lab) in Porto, (Radio Communications, Multimedia) in Covilhã, (Optical Communications, Radio and Microwave, Signal Processing, Power Systems) in Coimbra, (Signal Processing) in Leiria and (Optical Communications) in Aveiro were either revamped and significantly upgraded or got new equipment. Contrary to our initial expectations, it was not evaluated during 2009. Nevertheless it completed all the evaluation forms requested by FCT. The number of scholarships increased again in 2009, reaching an all time level. This is an important step in improving it performance and impact. In addition to the 186 Ph.D. scholarships funded by FCT, it hosted 25 young students under FCT scholarships for initiating scientific activity, plus 151 B.Sc. and M.Sc. and 4 post-doc fellowships in ongoing projects and 5 in mobility fellowships associated with the CMU-Portugal Program. During 2009, 97 nationally funded and 38 internationally funded projects were active, as shown in section 2.2. It is particularly noteworthy the fact that on the 31st of December it was involved in 27 FP7 projects (running and selected for funding) in addition to other 7 projects, where there was involvement of some it researchers from the Lisbon site. 10 ANNUAL REPORT 2009 - INTRODUCTION During 2009 it started to manage the logistics of the CMU-Portugal program by special contract with FCT. To reflect it 2009 activity some tangible objectives were defined in the Work Programme and Budget for 2009. These objectives together with the achieved values are given in Table 1 Graduate and post-graduate Foreseen Achieved MSc Theses 160 194 PhD Theses 30 22 Publications: Foreseen Achieved Books and Book Chapters 20 67 Papers in Journals 150 198 Papers in Conference Proceedings 400 519 activities: Table 1 - Foreseen and achieved scientific output in 2009. Achieved scientific output exceeded our forecast, in all areas, except in the number of concluded PhD theses which continues to fall short of the expected value, showing that supervisors systematically underestimate time requirements. it co-authored 16 patent applications in 2009. it received the following distinguished visitors: • President of the Republic, Prof. Dr, Aníbal Cavaco Silva, Coimbra, 16th of April • CEO of Portugal Telecom, Eng.

IT is a member of the CIENCIA VIVA, the National Agency for Scientific and Technological culture and co-operates in some of its events, namely those related with the diffusion of know-how on electromagnetic radiation and its effects on the human body. Project MONIT, (www.lx.it.pt/monit) is actively engaged in promoting and diffusing know how on electromagnetic radiation and mobile communications. Occasionally, through this project, IT offers two week training in the measurement of electromagnetic radiation. In cooperation with IST, IT started a one-year post graduation course in Telecommunications and Information Technologies. Sponsored by VODAFONE and in cooperation with IST, IT organized and implemented a 30-hour update course in Telecommunication Systems for high school teachers which was run three times in 2009 (80 teachers). Also in cooperation with IST, IT organized visits and demonstrations for high school pupils, involving about 1200 pupils (in 2009). 13 ANNUAL REPORT 2009- INTRODUCTION Some of the activities mentioned in detail in Annexes are closely interconnected with activities carried out by it researchers in the scope of their universities or polytechnics. Their inclusion in this Report is merely for the record. 14 ANNUAL REPORT 2009 – KEY IT INDICATORS 2.

Activities fall within the following five general topics: - Antenna Analysis and Design; - Wireless Circuits and Devices; - Waves and Propagation; - Transmitting and Receiving Systems; - Radio Networks. Antenna Analysis And Design Work on antennas followed three main streams: Small antennas for indoor applications, advanced antennas for RFID and antennas for mm-wave applications. Small terminal antennas Work continued on the development of UWB antennas, both for indoor personal communications and also for indoor localization applications. This included exponential slot based antenna configurations and dielectric loaded printed ring monopoles. A new wideband MIMO antenna array configuration was developed for MIMO WLAN Access Points with space and polarization diversity and was experimentally evaluated in terms of MIMO performance, using measured channel response data. The work followed the development of a MIMO channel sounder, based on a vector network analyzer. Small and compact multi-band microstrip patch antenna elements and arrays were developed for small personal terminal multi-standard applications. The analysis included antenna-user interaction characterization and the evaluation of mutual coupling and correlation. Single and multi-feed patches with slots have been considered. Flexible antennas made from electro-textile materials were designed and tested for wearable and body-implanted networks. Electromagnetic Band Gap (EBG) 27 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS structures have been incorporated into these antennas to reduce radiation into the user body. RFID Antennas Previous work on UHF RFID antennas was extended also for tags. A new folded tag antenna configuration with omnidirectional coverage was developed for embedding in special objects like suitcases for automatic luggage identification and tracking in sensitive environments. Also a wireless polling system was developed, based on passive UHF RFID technology. The activity also included the design of new antennas for confined detection of tagged RFID objects within medical cabinets. A new line of research has started on transparent antennas for specific RFID applications. Other Antennas Work also continued on the development of a fully functional mm-wave wireless USB system demonstrator using a recently developed mechanical steerable beam antenna concept based on a 60 GHz pivoting dielectric lens. A 1 Mbit/s data stream transmission was demonstrated with the Tx antenna tracking the movable receiver antenna. Wireless Circuits And Devices In this sub-area the research activities can be grouped under three general topics, one related to RF/microwave circuit design either CMOS based or GaN based, another to computer aided design of microwave/RF circuits and systems including simulation techniques and system/device modeling and a third one dedicated to wireless system design, mainly software defined radio and RFID/location systems. In all cases, the underlying applications fall within the wireless area. RF and Microwave Circuit Design In this area in the last year some active cooperation with Eindhoven Technical University, Holland, in development of RF front-ends, for Millimeter Wave applications was done, mainly some works on HBTs modeling of a 0.25um BiCMOS SiGe monolithic technology was obtain to explain the behavior of two active inductors. Some design rules were also derived. 28 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS Moreover during 2009 some advances were made on the following items: - A complete RF front-End Receiver prototype on 0.18um CMOS for WLAN 802.11abg and Bluetooth applications was designed and built. The receiver uses a heterodyne architecture with sliding IF frequency plan. - Spiral transformers modeling and design with electromagnetic simulation on 0.18um CMOS technology - A class E power amplifiers with driver for 2.4GHz WLAN applications on 0.18um CMOS technology - A Low Noise Amplifier for IEEE 802.11abg WLAN dual band applications with 0.18um CMOS technology. The amplifier uses a switched topology to operate at 2.4GHz and at 5.2GHz. - Work on monolithic power amplifiers started in 2009 within two research projects. The studies will address polar topologies with bias modulator circuits. An emitter will be designed for 2.4GHz applications. - Some efforts were also done in the area of power amplifiers, continuing the work of last years. Does the some new wireless transmitter architectures, mainly devoted to the design, implementation and test of switched-mode power amplifiers continue to growth. In this are of new transmitter architectures, some attention was also put in the envelope modulator design and its nonlinear impairments to the overall linearity and efficiency. Pre-distortion techniques were also employed with very good results that deserved several publications in conference proceedings and in journals. - The group also continues the effort with EFACEC of a project devoted to the study of the robustness test of a new and very promising semiconductor transistor technology: Gallium Nitride (GaN). At this moment the engineering prototype is already built and fully tested with very good results. - In the last year some new efforts with Portugal Telecom start also a new line of work in the design of point to point wireless links in the 18GHz band. 29 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS Wireless System Design During the year of 2009, in the are of wireless system design some work have been done in topics as RFID, DSRC, and SDR front ends. Referring RFID some new RFID readers were built for the 13Mhz band as also some Zig-Bee nodes for the implementation of a new wireless location engine based on RF fingerprinting, in this respect the overall system was built in IT. The work carried on with Brisa continues based on the develop of a new dual RSEDSRC (Dedicated Short Range Communication) system, for automatic identification and tool purposes, in 5,8GHz band, according with European standards to the physical, link and application layers (EN12834, EN12795, EN12253 and EN13372) and compatible with the actual Via Verde System. Design, fabrication and test of a DSRC system prototype were achieved. The main goal of this project is to “Development of Proof of Concept on wireless communications system for road applications, with emphasis on safety, following the WAVE recommendation”. While the standard IEEE-802.11.p is not completed, the development will follow the IEEE 802.11.a whenever necessary. Following the current 802.11p recommendations, basic functionalities will be implemented in order to comply with the identified applications and scenarios. In the area of Software define radio some new effort were done in the design of new RF front ends, especially in the study of techniques devoted to the increase of receiver dynamic range. This effort is aimed at the design of a complete cognitive radio transceiver that will allow the implementation of the cognitive radio approaches. Waves and Propagation Work in this sub-area includes fundamental work in the area of elctromagnetics of complex media with possible application to antennas and other relevant devices for wireless supporting technologies. It also includes studies for EM exposure assessment. 30 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS Electromagnetics of Complex Media In the last year some work has been done in homogenization and characterization of structured materials. Characterization of novel nonlocal metamaterials, with anomalous properties, such as lossless broadband anomalous dispersion or broadband negative refraction. A new prototype of wire media slab was developed to demonstrate experimentally its potential to present extreme values of effective permittivity, enabling its application for super resolution. Other metamaterial structures with near-zero effective permittivity were designed and experimentally evaluated, intended for manipulation of electromagnetic fields in the sub wavelength scale. In this sub-area in last year some continuing effort on Electromagnetics of Complex Media Chiral Media: Analysis of the propagation characteristics of chiral H-guides: Surface and leaky modes and respective chirality dispersion influence. Omega Media: Dispersion and losses in omega H-guide operation: Leaky en surface modes; Metamaterials: Leaky-mode propagation in metamaterial nonradiative dielectric (NRD) waveguides: Dispersive and lossy constitutive models; Propagation characteristics of DNG ridge waveguides: Proper leaky mode dispersion and propagation. Effect of material losses in metamaterial waveguide performance were developed. Numerical modeling Some work has been conducted on FDTD simulation of light propagation inside aSi:H structures. Understanding of light transmission, reflection and propagation inside semiconductor structures is crucial for development of photovoltaic devices. Using the FDTD is possible to simulate the propagation of electromagnetic waves with wavelengths in the range of the visible spectrum within a a-Si:H p-i-n structure. While the effects of surface reflections are easily taken into account by the algorithm, light absorption represents a more critical point, because of its nonlinear dependence with conductivity. 31 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS Public awareness and risk communication The six-years long effort to disseminate basic information to the general public on Electromagnetic radiation from personal communication devices and from operator base station antennas entered a new phase where the information is brought to secondary schools, which participate through a national wide contest that will award a prize for the best student work. Transmitting and Receiving Systems Performance studies were carried for WiMax/LTE, HSDPA and HSUPA at 900/2000 MHz bands and adjacent channel interference in UMTS systems in the 2000 and 2500 MHz bands. Some efforts have also continuing in the study of GPS navigation systems and on SAR radar solutions. Mobile communications The achievements in 2009 consist mainly in the study of LTE and WiMAX systems, were Point-to-Multipoint Cellular Scenario evaluated. Dynamic space-time- frequency Radio Resource Management scheduling algorithms valid for both technologies were also carried out. New link and system level modules were built for the simulators. Moreover the continuation of performance studies for HSDPA and HSUPA at 900/2000 MHz bands and adjacent channel interference in UMTS systems in the 2000 and 2500 MHz bands were done. Concerning 3G systems, an analysis and optimization study based on drive tests was also considered. Development of two WiMAX software tools: the first a static tool for fixed WiMAX and the other a dynamic simulator for mobile WiMAX. Study of capacity enhancement of wireless communications systems using MIMO techniques in particular with aplications for LTE in macrocell scenarios. Study of centralized cooperative spectrum sensing for ad-hoc disaster relief networks. In 2009 some work were also allocated to emerging services which demand higher data rates, especially in the downlink. Thus OFDM transmission techniques, together with MIMO antennas systems are the key approach to reach this development in cellular communications. 32 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS During 2009, research work focused on iterative frequency-domain receivers for block transmission techniques with rate-1 Space Time Block Coding (STBC) for two and four transmit antennas using both Orthogonal Frequency Division Multiplexing (OFDM) and Single-Carrier (SC) schemes were developed. The studied receiver includes an interference canceller which enhances the performance of the non-orthogonal STBC scheme with 2 and 4 transmit antennas, allowing performances close to those of orthogonal codes. These techniques are potential technologies to be used by the fourth generation of cellular systems. While MIMO OFDM is expected to be used for the downlink of LTE (being also considered by IEEE 802.15 (WIMAX)), the MIMO SC-FDE is a potential technology for the uplink of LTE, due to its simplicity when compared to MIMO OFDM, but achieving similar (or even better results) than MIMO OFDM. Several MIMO schemes are to be studied, as well as the study of advanced receivers for the SC-FDE. In addition, a particular pre-processing MIMO is to be developed, applied to OFDM (to be considered for the downlink of MIMO OFDM technology). Finally some efforts were put in the following aspects: efficient simulation methods for wireless communication systems using different modulation, coding and fading models with special emphasis on TCH (Tomlinson, Cercas, Hughes) codes, development of a new UWB system using TCH codes for both coding and synchronization aspects, evaluation of new techniques (namely hierarchical constellations, channel estimation, MIMO, OFDM) for use in LTE (Long Term Evolution) of UMTS systems and development of GPS related applications using dedicated hardware as well as the new satellite ground station. GNSS Solutions Some studies were focused on new GNSS solutions, including: -Development and implementation of algorithms for coordinated positioning systems; - Development and implementation of algorithms for precise positioning; - Following the work carried in 2008, a GPS monitoring station was developed at Instituto de Telecomunicações. 33 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS SAR Radars The work devoted to SAR radars was mainly based on development of techniques to estimate the velocity and trajectory of moving targets using Synthetic Aperture Radar data from a single sensor. In includes the development of a novel SAR ambiguity function with built-in capability to distinguish between targets moving in a predefined direction. IT researchers participate in a NATO Exploratory Team for Noise Radar Technology evaluation for application in future military systems. Radio Networks Several contributions on Physical Layer Awareness in the context of Future Internet were done. Within eMobility, contributions were given to the Strategic Research Agenda and to the Strategic Applications Agenda. The major results encompass: - the development of channel models for Body Area Networks; - the continuing development of CRRM algorithms for heterogeneous mobile communication systems; - the development of RRM algorithms for virtual mobile communications networks; - the development of various simulators for the air interface of UMTS-FDD, with HSDPA and HSUPA, and LTE, enabling the analysis of traffic aspects as well as load and handover ones. 34 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS 4.1.4 Running and Concluded Projects Overview Funding Agency Number AdI, German Aerospace Center (DLR) 1 ANACOM 1 Brisa 2 COST 2 EC - COST 1 EC - FP7 1 EFACEC 1 ESF 2 EU 1 EU, FP7 10 FCT 2 FCT/PTDC 6 GRICES - Programa Pessoa 1 iCentro 1 Instituto de Telecomunicações 1 TOTAL 33 Table 12 – Number of active projects in the Wireless Communications Area in 2009 35 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS Activity in Projects Acron / Ref Title ARNAGGS Advanced Receivers and Navigation Algorithms for GPS/Galileo Signals Funding FCT/PTDC Funding FCT/PTDC Descript.

Acron / Ref Title ASPIRE Advanced Sensors and lightweight Programmable middleware for Innovative Rfid Enterprise applications Funding EU, FP7 Descript. ASPIRE will research and provide a radical change in the current RFID deployment paradigm through innovative, programmable, royalty-free and privacy friendly middleware. This new middleware paradigm will be 36 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS particular beneficial to European SME, which are nowadays experiencing significant cost-barriers to RFID deployment. European networked enterprises in general and SME in particular are still reluctant to adopt RFID, since they perceive RFID as unprofitable or too risky. This is largely due to the fact that the adoption of RFID technology incurs a significant Total Cost of Ownership (TCO). ASPIRE will significantly lower SME entry costs for RFID technology, through developing and providing a lightweight, royalty-free, innovative, programmable, privacy friendly, middleware platform that will facilitate low-cost development and deployment of innovative RFID solutions. This platform will act as a main vehicle for realizing the proposed swift in the current RFID deployment paradigm. The ASPIRE middleware platform will take into account innovative European developments in the area of ubiquitous RFID-based sensing (i.e.,physical quantities sensing (temperature, humidity, pressure, acceleration), mobile sensing) towards enabling novel business cases that ensure high ROI (Return on Investment). The ASPIRE RFID middleware paradigm, as well as the unique and novel characteristics of the ASPIRE middleware platforms are thoroughly described in this proposal.

Today’s network architectures are stifling innovation, restricting it mostly to the application level while the need for structural change is 37 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS increasingly evident. The absence of adequate facilities to design, optimize and interoperate new networks currently forces a convergence to an architecture that is suboptimal for many applications and that cannot support innovations within itself, the Internet. 4WARD overcomes this impasse through a set of radical architectural approaches built on our strong mobile and wireless background. We improve our ability to design inter-operable and complementary families of network architectures. We enable the co-existence of multiple networks on common platforms through carrier-grade virtualization for networking resources. We enhance the utility of networks by making them self-managing. We increase their robustness and efficiency by leveraging diversity. Finally we improve application support by a new information-centric paradigm in place of the old host-centric approach. These solutions will embrace the full range of technologies, from fibre backbones to wireless and sensor networks. The 4WARD results will allow new markets to appear, redefining business roles and creating new economic models. We will establish the Future Internet Forum as a leading standards body, enabling these new markets and opening them for old and new players alike, increasing opportunities for competition and cooperation and creating new products and services. These goals can only be achieved by gathering a strong, industry-led consortium of the leading operators, vendors, SME, and research organisations, with the determination, skills, and critical mass to create cross-industry consensus and to drive standardisation. The project is designed for multiple phases; the first one will establish the core concepts and technologies and last for two years. The planned effort of about 2200 person months corresponds to the strategic importance of this endeavour.

Acron / Ref Title FUTON Fibre Optic Networks for Distributed, Extendible Heterogeneous Radio Architectures and Service Provisioning Funding EU, FP7 Descript. Two current trends in wireless communications are the development of 46 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS new broadband component and the integration of heterogeneous wireless networks, to achieve the vision f the so-called 4G network. The FUTON project addresses both issues by proposing the development of a hybrid fibre-radio infrastructure transparently connecting remote antenna units to a central unit where a joint processing can be performed.

Hyperspectral sensors are now able to produce hundreds of images, corresponding to different wavelength channels, for the same area on the surface of the Earth. Such wealth of spectral information applications, has opened including ground-breaking environmental perspectives and urban in many monitoring and assessment, target detection for military and homeland defense/security purposes, and risk prevention and response. The latter includes tracking wildfires, detecting biological threats, and monitoring oil spills and other types of chemical contamination. The core strategy of HYPER-I-NET will be to create a powerful interdisciplinary synergy between different domains of expertise within Europe, and use it to break new grounds in areas related with hyperspectral imaging. This will be achieved by organizing a well structured multidisciplinary training programme that will cover all the different aspects that comprise the hyperspectral data processing chain, ranging from sensor design and flight operation to data collection, processing, interpretation, and dissemination. As a result, the theme of HYPER-I-NET is at the confluence of heterogeneous disciplines, such as sensor design and calibration, aerospace engineering, remote sensing, high performance computing, image/signal processing and Earth observation related products. The main objectives of HYPER-I-NET will be to: 1. Bridge the gap between sensor design and hyperspectral data exploitation in remote sensing activities in Europe.

In the context of the solution being sought, a hierarchical communication system will be needed to deliver the data from the WBAN that is installed in pregnant woman. Although the main focus of SMART-CLOTHING is to produce the sensors integrated into the clothes and to integrate them into the WBAN, broader WSAN (Wireless Sensor and Actuator Network) solutions are being envisaged. e.g., in the context of high competition teams, where the objective is to design and develop instrumentation to support clinical intervention for the rehabilitation of neuro-muscular and muscular-skeletal functions caused by traumatic injuries that occurred either during sports activity. As the biomechanical analysis of the human movement needs a use of complex hardware and software systems, there is an opportunity for wireless communications and instrumentation and measurement research to integrate these devices into tiny wireless sensor devices, with simplified network capabilities, that will enlarge amplitude and freedom of the movements. In low risk pregnancies, between the medical sessions that occur weekly during the last five weeks of pregnancy, the foetal health can change suddenly. As a consequence, the majority of foetus fatalities in the end of pregnancy verifies in the low risk group. Therefore, it is important an obstetric tracing, allowing for the identification of sudden changes in the foetus health, by monitoring the foetus movements and the foetal cardiac (FC) frequency, and the development of easy to wear telemedicine gear will allow for remotely monitoring the pregnant women, and the health of the baby she carries. The data delivery method is chosen by a decision device and the choice can be either the Wi-Fi system or the WiMAX system, or even the GSM system from a hierarchical network. One intends to distinguish the cases where mobility is a need from the remaining ones. A decision device should be incorporated between the WSN and the specific network that this device 56 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS can choose to Contributions reach are the being Hospital, given on where the embedded gynaecologist is. microcontrollers for integration of clusters of motes into hierarchical communications networks. Embedded electronics with advanced sensing and communication capabilities is justified by the lack of general purpose WSANs that cope with heterogeneous application requirements. In SMART-CLOTHING, new algorithms and protocols are being developed to optimize the trade-off energy consumption/ processing and communication capabilities, namely in the MAC (Medium Access Control) layer and aspects of data aggregation. Cross-layer design between MAC and physical layers will be addressed, and the interactions with network and transport layers will be considered as well. Acron / Ref SWIPA Title Switching Mode Power Amplifiers for Wireless Communications Funding IT Descript. The main objective of this project is to study the feasibility of incorporating digital techniques in wireless power amplifiers. For that, it will address both the system level concepts of transmitter architectures as the Polar and Cartesian; and the implementation level of switching RF power amplifiers. So, this objective can be decomposed into: 1. Investigate non-conventional wireless power amplifier and transmitter architectures that can bypass the traditional compromise between PAE, efficient spectral usage and linearity. 2. Identify the practical limits of bias-modulated digital power amplifiers in Cartesian and Polar transmitters in terms of: (i) Requirements imposed on the RF power devices by bias-modulated switching operation; (ii) Parasitic AM-to-PM modulation; 57 ANNUAL REPORT 2009 – WIRELESS COMMUNICATIONS (iii) Class-D AM amplifier bandwidth; (iv) Zero bias RF carrier leakage (zero-AM off-set); (v) AM envelope modulation linearity; (vi) Time-delay mismatch between the AM and PM modulation paths. Acron / Ref Title U-BOAT Ultra-Wide Band Transmission for Ad Hoc Networks Funding Descript. This project deals with UWB-based ad hoc networks. The physical layer objective is the development of signal processing schemes to improve the performance (for both impulse radio and continuous-wave transmission techniques). The MAC layer considers asynchronous data transmission and structured/unstructured architectures. It will study broadcast/unicast performance, considering cross-layering optimizations. The objectives include the definition of an abstraction suitable for the network layer for supporting differentiated levels of quality of service, and its concrete implementation, supported on different resource reservation mechanisms. The network layer objectives include the analysis of the behavior of ad hoc routing algorithms and service location services, and their optimization introducing cross-layering tuning at the MAC and physical layer. An important objective is to take advantage of the complementary competences of the teams involved in the project, leading to relevant contributions to the specification UWB-based ad hoc networks and to stronger skills, in both teams.

Os sistemas de localização estão já fortemente implementados no mercado europeu, devido especialmente aos navegadores de automóveis, ou a soluções para gestão de frotas. A grande dificuldade de transportar estes sistemas para pessoas, está no facto da integração ainda não ser eficiente para a sua conveniente integração em roupas ou outros elementos que não impliquem a existência de um elemento de grandes dimensões. Por essa razão o principal objectivo deste projecto é a criação de barreiras virtuais ou sistemas de alarme para pessoas com necessidades especiais através de dispositivos miniaturizados. Pretende-se com recurso a tags de rádio, com funcionalidades de comunicação e de localização, criar barreiras virtuais para monitorizar a movimentação de pessoas com necessidades especiais, caso de doentes, idosos ou crianças, assim como possibilitar o envio de uma alarme de emergência com a localização da pessoa. No âmbito do projecto as limitações técnicas prendem-se especialmente com a segunda componente do projecto, ou seja a construção de um sistema de rádio comunicação/localização que permita a comunicação com o exterior. A autonomia energética deste equipamento também poderá ser um das actuais limitações deste tipo de equipamentos.

Optical Components and Subsystems The work carried out in this sub-area concentrated on the modeling, performance evaluation, optimization and implementation of key components and subsystems for all-optical networks. The modeling and simulation tools to assess the static and dynamic responses of optimized, non-conventional DFB laser structures (Distributed Coupling Coefficient – DCC, Multiple-Phase-Shift – MPS, and Corrugation Pitch Modulated - CPM lasers), to be used in optical communication systems using direct modulation, was performed. The optimization of these laser structures (DCC, MPS, CPM or hybrid) has been implemented using matrix techniques (TMM). An improved model to discriminate the adiabatic and transient frequency chirping in directly modulated lasers was developed. The study of the frequency response of semiconductor PIN photodiodes for optical communications continued. The effect of wavelength on the transit time limited frequency response was considered, by using a previously developed numerical model which may be applied to devices with an arbitrary electric field profile in the absorption region and non-uniform illumination. The combined effects, regarding the absorption layer width, bias voltage, temperature, wavelength and direction of the incident light, on the transit time limited frequency response of PIN photodiodes were also investigated. An analytical model accurately describing the evolution of the relative state of polarization between two signals in high-birefringence fibers was developed and experimentally validated. The influence of the stimulated Raman scattering in the 96 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS four-wave mixing process in high-birefringence fibers was theoretically analyzed. A new method to measure the effective nonlinear parameter of a fiber was developed and experimentally validated, by comparing theoretical and experimental four-wave mixing results in a low power regime. In the area of optical amplification, a new method was developed to mitigate the transient effect in optical fiber Raman amplifiers. This method is based on a pumpcontrolled gain-locked system and is suitable for pump-reflecting Raman fiber amplifiers. This method was submitted for a patent registration. Optical amplification in the visible spectral region for plastic optical fiber applications was also studied. Reflective semiconductor optical amplifiers have been characterized under RF modulation, in order to optimize its parameters for radio over fiber applications. Work has also been carried out in the area of production and characterization of components in integrated optics. Passive devices (Y-branch splitter), based on solgel technologies, have been developed for passive optical networks. In the area of all optical processing for high bit rate optical networks, advanced techniques for all-optical routing, tunable dispersion compensation, optical filtering, pulse shaping, clock recovery, optical code division multiplexing and regeneration were developed. An acoustic wave generator for optical fibers to be used in tunable filters was developed. Research work on all optical signal processing with semiconductor optical amplifiers started, and a lab experiment has been designed for evaluating new applications, namely static RAM. In the area of new techniques and devices for microwave photonics, a novel beam forming technique for phased array antennas has been studied. 97 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS Work in the area of optical sensors included: the development and optimization of a fiber monitoring system, based on fiber sensors and wireless transmission; novel plastic fiber sensors for refractive index and bending measurement; a novel sensor for simultaneous refractive index, temperature and stress measurement based on a tilted fiber Bragg grating; and a novel sensor for simultaneous measurement of temperature and deformation based on a tapered fiber. Optical Communication Systems Advanced modulation formats for optical fiber communication systems were investigated. A novel semi-analytical method for BER evaluation in simulated optical DQPSK systems was developed, and an accurate method of performance assessment for DQPSK systems in presence of receiver imperfections was proposed. Pseudo-linear transmission regime with high-speed optical singlesideband (OSSB) signals and electrical dispersion compensation was investigated. An analytical method to estimate the degradation of signal quality in case of OSSB signals with different modulation formats was investigated. 3R all-optical regenerator work was pursued. The impact of the switching window shape on the performance of a chain of reamplification, reshaping, and retiming alloptical regenerators based on a non-linear gate was analyzed. In the area of radio over fiber (RoF) systems, optical filters were developed and optimized for these systems. Performance of BPSK vs QPSK for optical distribution of orthogonal frequency division multiplexing (OFDM) ultra-wideband (UWB) radio signals in fiber-to-the-home (FTTH) networks was compared. The state-of-the-art of joint optical/radio OFDM transmission impairment compensation was identified. Research on 60 GHz MMW band focused on photonic techniques for generation of MMW sub-carriers has begun during this reporting period. Transmission of 802.11g signals over a 10Km RoF link was demonstrated. The feasibility of a photonic structure for photonic analog-to-digital conversion (PhADC) applications was investigated in the UCELLS project. The main aim is to realize the ultra wideband radio spectrum management. The proper operation of the Ph-ADC photonic structure was experimentally demonstrated. 98 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS A semi-analytical approach that allows evaluating the transmission performance of direct-detection OFDM signals over optical fiber was proposed. The development of a rigorous method to assess the performance of the transmission of OFDM signals in optically preamplified receivers with direct-detection was started. Optical Networking The research work on access networks has continued, focused on next generation passive optical networks (PONs) and their convergence/integration with MANs. The search for new CDMA codes has been pursued, by exploring their applicability in access networks with coherent modulation and detection. Work has started on the functional requirements of fully-converged integrated optical-wireless access architectures started. The application of Raman amplification in PONs and demonstration of the concept of optical powering of remote nodes was studied. Work on optical burst-switched networks continued in 2008. A framework for routing path optimization by using an ant colony optimization technique was developed and its performance was evaluated by network simulation. A strategy for optimizing the structure of an OBS burst-switch by using wavelength contention minimization algorithms was proposed. The use of Raman amplification in optical burst switched networks was analyzed and compared (experimentally and by simulation) with other amplification technologies (EDFAs and SOA). Work on transporting 100 Gbit Ethernet traffic over OTN (Optical Transport Network) networks has continued. Work on ILP (Integer Linear Programming) and heuristic formulations taking into account aspects like virtual concatenation, multipath routing, and differential delay minimization by including also wavelength assignment was realized. The problem of generating physical realistic optical transport network topologies was addressed. This type of network has characteristics that differ from scale-free networks, such as the Internet. Based on the analysis of a set of real transport topologies, relevant characteristics were identified and assessed. A method to 99 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS generate realistic topologies was proposed and validated by comparing the characteristics of computer-generated and real-world optical transport networks. Investigation on physical layer impairments was pursued. An analytical treatment appropriate to compute the performance of DPSK receivers in the presence of inband coherent crosstalk originated inside the optical nodes was developed. In the areas of high power in optical networks, guidelines for the transmission of high power optical signals in fiber systems were derived, and the constraints resulting from the fiber heating and development of strategies to the mitigation of the fiber fuse effect were studied. 100 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS 4.2.4 Running and Concluded Projects Overview Funding Agency Number COST, NA 2 ESF 2 EU 2 EU-FP7 5 FCT 2 FCT/PTDC 7 JustBit 1 PT Inovação 1 QREN PTIN 1 TOTAL 23 Table 18 - Number of active projects in the Optical Communications Area in 2009 101 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS Activity in Projects Acron / Ref BONE Title BONE Funding EU - FP7 Descript.

Acron / Ref Title MP0702 COST MP0702 - Towards functional sub-wavelength photonic structures 102 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS Funding COST, NA Descript. The main objective of the Action is to establish active links between European laboratories working in the field of artificial materials for photonics applications, where the structural dimensions are at or below the wavelength of light. Fabrication of such structures has become possible due to the expertise delivered by nanotechnology, which opens the way to the study of new functional artificial materials and plasmonic structures, promising progress in miniaturisation - and which will allow exploration of new aspects of light-matter interaction. The goal is to increase knowledge about the basic mechanisms of the interaction of light with matter on a sub-wavelength scale. The scientific innovation concerns: the basic mechanisms of light-matter interaction in microand nanostructured materials - including metals (plasmonics), the trade-off between strong localization and propagation losses, photonic diagnostic instruments, and non-linear effects. The technological impact of the Action will lead to the implementation of advanced optical equipment and devices with high performance and low cost. The scientific transformation resulting from the Action will facilitate interconnection between topics that will produce new results in the field of photonics and pave the way to the forthcoming era of nanophotonics.

Acron / Ref Title COST 291 Towards digital optical communications 109 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS Funding ESF Descript. The primary objective of the COST Action “Towards Digital Optical Networks” is to focus on novel network concepts and architectures exploiting the features and properties of photonic technologies, to enable future telecommunications networks. It is aiming to propose a new generation of systems and networks that will accommodate the unpredictable and growing size of data files and messages exchanged and stored as well as real time services (e.g. voice, video etc) over global distances requiring an agile Communication Grid supporting quality of services. These need to provide end-toend bandwidth for transmission of traffic for applications such as information retrieval, downloading (often multimedia) web software, exchange of various type of software (hundreds of Mbytes) and data models (Gbytes) etc as well as real time multimedia applications. These systems need to be very flexible and rapidly reactive to efficiently accommodate the abrupt and unpredictable changes in traffic statistics introduced by current and future applications with low endto- end latency. They will enable advanced features such as efficient and simple multicasting and broadcasting of broadband signals. In general, they need to support a future proof, flexible, efficient and bandwidth-abundant fiber-optic network infrastructure capable of supporting ubiquitous services in a resilient manner offering protection and restoration capabilities as well as secure services to the users. Transparency to various digital signals and protocols is required to eliminate the need for multilayer complex network architectures suffering by poor scalability for data services, high latency, complicated network management and high cost. This migration can be gradually achieved by removing and/or integrating intermediate layers. Flat and upgradeable network architectures supporting photonic core and access technologies with intelligent edge nodes at the interfaces will form a universal infrastructure offering a variety of 110 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS services supported by multiple operators. The ease of maintenance, provisioning and resilient operation required in this type of networks will be achieved through advanced routing and management mechanisms, eliminating the requirement for ever increasing amounts of complex software raising the cost and limiting the network reliability and availability. This advanced photonic infrastructure will employ optical signal processing and dynamic impairment management to eliminate the limitations of the analogue nature of traditional optical networks, dense wavelength division multiplexing technologies for signal transmission and routing, and optical packet and/or burst switching to provide fine bandwidth granularity, network efficiency and flexibility. Acron / Ref TURBO Title Transmission of UltRa wide-Band radio signals over Optical fibre Funding FCT Descript. This project proposes to investigate the performance impairments of the orthogonal frequency division multiplexing ultra wideband (OFDMUWB) radio signal transmission in fiber-to-the-home (FTTH) networks and optimize the system parameters through analytical and numerical simulation work, and to experimentally demonstrate the main results obtained. Particularly, the study and the assessment of the main system impairments is performed, such as: (i) electrical crosstalk associated with multi-channel OFDM-UWB transmission, (ii) linear and non-linear fibre effects, (iii) optical crosstalk associated with the transmission of several optical channels using dense wavelength division multiplexing (DWDM). Different techniques to reduce the performance degradation caused by such limitations are also investigated. The work to carry out along this project targets the transmission of OFDM-UWB radio signals in FTTH networks using external modulation 111 ANNUAL REPORT 2009 – OPTICAL COMMUNICATIONS (EM) and direct modulation (DM) of the emitter laser. The transmission of OFDM-UWB radio signals over multi-mode fibre is also a topic to be investigated in the project, since this type of fibre is used in the user’s premises due to its easy maintenance and utilization.

Aveiro Security and Quantum Information Table 23 – Non-permanent Collaborators working in the Neteworks and Multimedia Area in 2009 142 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA 4.3.3 Summary of Research Achievements The work in the area of Networks and Multimedia is organized in several topics: - Architectures and protocols; - Security and quantum information; - Traffic engineering; - Network operations, management, and planning; - Network applications and services - Processing, analysis and coding of audio and visual information; - Pattern recognition and automatic learning; In the following, we briefly summarize the main achievements in each of these topics. Architectures And Protocols Mathematical foundations of Internet routing – Contrary to many other areas of engineering, Networking and the Internet developed almost exclusively through experimentation, without firm supporting models. The Internet is a success, but one is left to wonder whether its behavior is understood, whether its growth is sustainable, and whether better designs are possible for itself and its subsystems. Good models are important in this regard. We set out a model to understand the connectivity provided by route-vector protocols subject to routing policies at the various nodes. We identified two algebraic properties that lead to fundamental theorems and efficient computation of this type of connectivity: export-myopia and export-isotonicity. Export-myopia means that the decision to export a route to a neighbor node depends only on the previous neighbor node from which the route was learned, and not on the attributes of the route. Export-isotonicity means that if a node does not export a route to a neighbor node, then it also does not export to the same neighbor node any less preferred route. Under export-myopia and exportisotonicity, we were able to prove a link version of Menger's theorem for usable paths stating that the minimum number of links that usably separates a node from the destination equals the maximum number of usable link-disjoint paths from the former to the latter, and that a route-vector protocol does find a usable path whenever one exists. In the end, we were able to present a polynomial-time algorithm to compute the connectivity of route-vector protocols. Our work can thus be regarded as a generalization of classical connectivity results for when not all 143 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA paths are usable and they are to be discovered through a route-vector protocol. We have applied the theory to an annotated description of the Internet provided by the CAIDA data sets. We quantified the loss in Internet connectivity due to the traditional routing policies which substantiate the localized, competitive behavior of ISPs. We also presented more general routing policies and assessed their connectivity. And we determined how much of the Internet intrinsic connectivity is recovered with simple backup policies. Network Coding Multicast in Satellite Networks - The broadcast nature of satellite networks such as DVB-RCS based systems provides a highly effective medium for content distribution, especially in the case of geographically scattered clients. Non-realtime services typically rely on application level protocols that often use forward error correction (FEC) and carousel data cycling schemes in unidirectional links. The presence of a feedback channel in satellite networks is mostly unexploited in the context of reliable multicast services. We show that network coding protocols, which mix different packets by means of algebraic operations, offer a native and transparent solution for reliable multicast over satellites. When employing a feedback channel, network coding can reach near real-time performance at an efficiency level close to known theoretical bounds for lossy satellite links. Network Coding Simulation in Large-Scale Topologies - We developed NECO, a high-performance simulation framework dedicated to the evaluation of network coding (NC) based protocols. Its main features include: (1) definition of graphs representing the topology (which can be generated randomly or predefined by means of a standard representation), (2) modular specification of network coding protocols, (3) visualization of the network operation and (4) extraction of key statistics. The simulator is entirely written in Python and can be easily extended to account for extra functionalities due to its modular architecture. As a proof-ofconcept we carried out and published a comprehensive study of the impact of network topology on the performance of network coding with respect to throughput and achievable security levels. Our findings, which can be used to find the best overlay topologies for network coding at the application layer, confirm that the benefits of network coding are largely dependent on the network topology. Network Coding Meets TCP – We propose a mechanism that incorporates network coding into TCP with only minor changes to the protocol stack, thereby 144 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA allowing incremental deployment. In our scheme, the source transmits random linear combinations of packets currently in the congestion window. At the heart of our scheme is a new interpretation of ACKs - the sink acknowledges every degree of freedom (i.e., a linear combination that reveals one unit of new information) even if it does not reveal an original packet immediately. Such ACKs enable a TCPlike sliding-window approach to network coding. Our scheme has the nice property that packet losses are essentially masked from the congestion control algorithm. Our algorithm therefore reacts to packet drops in a smooth manner, resulting in a novel and effective approach for congestion control over networks involving lossy links such as wireless links. Our experiments show that our algorithm achieves higher throughput compared to TCP in the presence of lossy wireless links. We also establish the soundness and fairness properties of our algorithm. Optimization of Wireless Communication Systems - This research work has been exploring the intersections between information theory and estimation theory in the analysis, design and optimization of future communications systems. The most relevant research problems include [18]: (a)The optimization of linear precoders for multiple-input multiple-output Gaussian channels with arbitrary inputs; (b)the optimization of linear precoders for fading multiple-input multipleoutput Gaussian channels with arbitrary inputs. Of particular relevance is the use of the simple connection between the derivative of the mutual information and the nonlinear MMSE to address open problems in the optimization of the reliable information transmission rate of communications systems in innovative manners. Probabilistic Flooding in Dense Networks - We consider probabilistic information dissemination in stochastic networks. In our problem setup a source node intends to deliver a message to all other nodes in the network (“flooding”). First, the source node transmits the message to all its neighbouring nodes. Each of them then forwards the received message with some network-wide probability pf. A natural question arises: which forwarding probability pf should each node use such that a flooded message is obtained by all nodes with high probability? In other words, what is the minimum pf to achieve a high global outreach probability? We first present a generic approach to estimate the probability of achieving global outreach. We then focus on Erdos Renyi random graphs (ERGs) and Random Geometric graphs (RGGs). For ERGs we are able to derive the exact expression for the global outreach probability given the network topology and the flooding parameters. For RGGs we derive an asymptotic expression. A simulation study 145 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA complements these results. We also take a system design perspective to show parameter settings that lead to global outreach. Energy-Efficient Routing in Underwater Sensor Networks - Underwater wireless sensor networks consist of a certain number of sensors and vehicles that interact to collect data and perform collaborative tasks. Designing energy-efficient routing protocols for this type of network is essential and challenging because sensor nodes are powered by batteries, which are difficult to replace or recharge, and because underwater communications are severely affected by network dynamics, large propagation delays and high error probability of acoustic channels. Practical Source-Network Coding for Sensor Networks - Considering the case of correlated sources, where data from one source already contains some information about other sources, information theoretic results tell us that the amount of data, which needs to be transmitted from the source to the sink (at a given quality), can be reduced by considering the source correlations within the coding scheme. Distributed source coding techniques allow us to do so. In scenarios where correlated source data needs to be communicated over a network it is possible to perform distributed source coding and network coding separately. However, this approach is shown to be non-optimal in general scenarios. The solution to this problem would be to perform joint source-network coding which is a highly challenging task mostly due to the complexity of the decoder. The problem lies within the fact that the decoding complexity of distributed source coding schemes generally increases exponentially with the number of source nodes. We show how to perform near-optimal, yet computationally tractable, joint sourcenetwork decoding using factor graphs and belief propagation techniques. Also provided is a proof-of concept in form of a working implementation. Protocols and Architectures for Vehicular Ad-hoc Networks - The goal of this line of research is to investigate how vehicle-to-vehicle communication can improve the user experience and the overall efficiency of vehicle and road utilization. Vehicle-to-vehicle communication will be enabled by means of Vehicular Ad-Hoc NETworks (VANETs), a novel type of mobile ad hoc networks (MANETs) that has recently attracted significant interest from governments, academia, and industry, due to its potential to help save lives, increase the traffic efficiency, and provide a more pleasurable experience for drivers and passengers. VANETs provide an opportunity for myriad of new applications, including location-based information 146 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA dissemination, vehicle based social networking and distributed interactive games. Our results so far include a detailed study of urban connectivity in VANETs using our large-scale traffic simulator DIVERT, an evaluation of the quality of service that can be guaranteed in highway environments with unicast sessions, and various prototypes including the see-through truck, a system that helps drivers overtake trucks by feeding a video stream of what the truck sees using a the vehicle-tovehicle wireless link. Transport architectures for satellite networks – Phase 2 of project TOP, dealing with the study of algorithms for TCP congestion control appropriate for satellite network environments, was completed successfully during 2008. This phase dealt with the implementation and test of the algorithm developed in Phase 1. The work performed in 2008 consisted of further refinement of the test plan towards the performance evaluation of a prototype implementation, followed by a measurement campaign performed at the ESA-ESRIN site (Frascati, Italy) site using an Eutelsat satellite link. Networking and security issues in real-time applications - This research stream was focused on problems related to high-speed network infrastructures and security issues for real-time multimedia applications in an evolution scenario where some applications and services have gradually migrated from the client-server paradigm to the peer-to-peer (P2P) computing paradigm. Particular attention was paid to the following issues: (i) Autonomic and Real-time Detection and Classification of Encrypted P2P File Sharing Traffic and P2P TV Traffic; (ii) Autonomic and Real-time Detection of Internet Traffic Anomalies; (iii) Strategies for Robust Media Streaming over P2P Networks Based on Multiple Description Coding; (iv) Tradeoff Between Network Performance and Security Issues in High-Speed and Low-Latency Communications; (v) Detection of Intensive Attacks in Real-Time and High-Speed Networked Environments; (vi) High-speed Technologies, Protocols and Architectures for Multimedia Networks. Wireless ad-hoc and mesh networks - GEMS continued to work on the Home Networking area completing the development of a distributed middleware architecture for applications and devices to seamlessly interoperate and capable of creating an automated home solution with service discovery facilities covering the entertainment, security, communications and automation aspects and coping with the self-organization, integration and user-friendliness requirements that are typical 147 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA of such environments. This project has been funded by LEMe as a result of an internal LEMe project contest. This resulted in a MSc successfully completed. From September onwards, the project has entered a second phase were applications based on the middleware developed in the first phase are being developed. The integration with networked embedded systems for monitoring and actuation purposes in the home environment is also foreseen. Vehicular Delay-Tolerant Networks - In the area of Delay Tolerant Networks (DTN) NetGNA proposed a new network architecture called Vehicular Delay Tolerant Network (VDTN). A VDTN layered architecture was proposed. The main objective of this architecture is to provide a low-cost connectivity solution for isolated and dispersed regions with no networks infrastructure. VDTN architecture handles nonreal time applications, exploiting vehicles to enable connectivity under unreliable scenarios with unstable links and where an end-to-end path may not exist. Intuitively, the use of stationary store-and-forward devices (relay nodes) located at crossroads where vehicles meet them and should improve the message delivery probability. The proposed architecture is based on the concept of Delay Tolerant Networks (DTN) and can be applied to various scenarios, including rapid deployment of emergency communication systems when all communication links have failed. We evaluated routing strategies for rural connectivity, the performance improvement with relay nodes, and the Impact of Storage Capacity Constraints on VDTNs. New Scheduling and Dropping Policies for Traffic Differentiation on VDTNs were also proposed. The first version of a VDTN prototype was presented. The work on VDTNs is supported by the Internal Project VDTN@Lab, a joint collaboration between Covilhã and Aveiro groups. Our group is also involved on the NoE Euro-NF FP7-IST Project, leading the workpackage JRA 1.2 – Core and Metro Architectures. Wireless Sensor Networks & eHealth - In area of sensor networks we proposed a solution for detecting intra-fraction motion in patients undergoing radiation treatment using a low-cost wireless accelerometer. Another important contribution from sensors application on eHealth is a novel intra-body sensor for vaginal temperature monitoring. The motivation for including IP on wireless sensor networks was discussed taking into account future research goals related with Plugand-Play functionalities for IPv6-enabled wireless sensor networks. The work on wireless sensor networks and eHealth is supported by the Internal Project BodySens. On eHealth, beyond applications of wireless sensor networks and mobile and ubiquitous applications, we surveyed the state of the art on health information 148 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA systems, addressing their concepts, methodologies, tools and applications. Several security approaches were proposed for user authentication for wireless sensor networks, for voice transmission over multipath wireless ad-hoc network, and a trust management scheme for enhancing security in pervasive wireless networks. Our group is also involved on the NoE Euro-NF FP7-IST Project. Wireless sensor networks - GEMS continued its efforts in this area. As a whole, GEMS has been involved in 6 projects. Regarding our participation in NEWCOM ++ (Network of Excellence in Wireless Communications), a NoE FP7-IST Project addressing research problems in the field of wireless networks, namely the challenges posed by ubiquitous network infrastructure and architectures, our group has been particular active in one of the technical work-packages (WP11) of the project, which started in 1/2008. In WP11 - Opportunistic Networks - the pervasive communication scenarios, were delay-tolerant applications are expected to play and important role are the main targets. Opportunistic networks exploit human (and/or machine) mobility and local forwarding in order to distribute data. Information can be stored and passed, taking advantage of node’s mobility, or forwarded over a wireless link when an appropriate contact is met. In this context, the proposal, design and development of a new routing protocol for opportunistic environments, has been carried out, which resulted in a MSc dissertation and a publication submitted to an international conference in the area. As for the projects that started in previous years, the effort on specific applications of WSN involving interesting engineering problems continued throughout 2009, while a consolidation of the work on the campus WSN test-bed (called Tagus-SensorNet) has been carried out in 2009. The platform has been evolving since its deployment in 2007 and gave rise to interesting experiments and research work. Some results were shared with the scientific community through a journal paper describing the development and deployment of the Tagus-SensorNet, published in the International Journal of Sensor Networks (IJSNet). Furthermore, new results regarding energy management of the Tagus-SensorNet platform have also been submitted to the same journal, and we are waiting its evaluation. Finally, we have been able to develop a new sensor node hardware which will allow us to, not only have domain on the software part of WSN but also on the hardware part and, in particular, on the HW-level aspects of energy management; this is a natural evolution of the group's hardware area from where several sensor boards (3 presently) have emerged in the last 3 years. Also, we have launched a project 149 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA concerning the operation and maintenance problems of WSNs - Modulus - involving the design and development of a new WSN's middleware capable of ease the setup and maintenance (and beyond) of complex WSN applications. Vehicular ad-hoc networks - So far, in most vehicular applications, navigation and communication are viewed as separate capabilities with little or no relationship between each other. Although much work has already been done related to the enhancement of vehicular communication protocols, they do not consider the leveraging of rich data sets provided by GPS receivers, such as position information, roadmap geometry, and traffic conditions, which would improve the utilization of the wireless medium and provide higher quality of service for a wide range of applications. With this goal in mind, we shall seek for opportunities to use GPS data at every layer of the communications protocol stack. The work being performed aims to improve transport layer communications with geographic information in a cross-layer approach, studying the influence of lower layer characteristics and enhancements, mainly related to the MAC layer, in the transport layer. On the other side, the reliability of vehicle-to-vehicle communication depends on several factors: vehicles density, location, mobility models and radio propagation. In this sense, the support of infrastructure points, denoted as Road Side Units (RSU), may be used to increase reliability in vehicular communications. However, the number of RSUs needs to be minimized to decrease the communications cost; this requires an unusual optimization process, which needs to operate in this extremely dynamic environment. The choice of the optimal number, location and characteristics of RSUs to significantly optimize communication, dependent on the vehicular network and road characteristics, aided by GPS traffic information and dynamic trends on traffic loads, are problems that are subject of this work. The research of network protocols and extended network applications in these optimized networks will be also addressed. Wireless Mesh Networks - Distributing multimedia content over wireless networks is challenging due to the limited resource availability and the unpredictability of wireless links. As more and more users demand wireless access to (real-time) multimedia services, the impact of constrained resources is different for different media types. Therefore, understanding this impact and developing mechanisms to optimize content delivery under resource constraints according to user perception will be key in improving user satisfaction. In this paper, we develop a novel scheduling algorithm for multi-hop wireless networks, which optimizes packet 150 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA delivery for multiple audio, video and data flows according to user perceivable quality metrics. We formulate a multidimensional optimization problem to minimize the overall distortion while satisfying resource constraints for the wireless links. Our Quality-of-Experience (QoE)-optimized scheduler makes use of models to determine the user’s perception of quality that are specific to the type of service being provided. Context-aware Virtual Wireless Mesh Networks – The flexibility and selforganization properties of Wireless Mesh Networks (WMNs), and the benefits arising from the split of a physical network in several context-aware Virtual Networks (VNs), are a two-fold force to deal with the huge heterogeneity of user requirements and network resources in a future Internet architecture. In this scope, we provide a novel context-aware architecture for WMNs, that supports user requirements on demand by the deployment of several adaptable VNs for different context-aware purposes. We developed an analytical model for the proposed architecture. We aim to provide and define the limits of our multi-VN approach, in terms of the number of VNs, attached mesh clients, and virtual nodes per VN, in order to accomplish feasible delays for different data or control communication requirements. Wireless access networks - The IEEE 802.16 standard represents the state-ofthe-art in technology for metropolitan area broadband wireless access networks. The point-to-multipoint (PMP) mode of IEEE 802.16 has been designed to enable quality of service (QoS) in operator-controlled networks and, thus, is foreseen to complement existing third generation cellular networks. In contrast, the optional mesh mode of operation in IEEE 802.16 enables the setup of self-organizing wireless multi-hop mesh networks. A distinguishing characteristic of the IEEE 802.16 standard is its support for QoS at the MAC layer. However, the QoS specifications and mechanisms for the PMP and the mesh mode are not consistent. Research has been performed to integrate a novel QoS architecture in order to enhance the IEEE 802.16 mesh mode of operation. In particular, we have evaluated scheduling algorithms and admission control mechanisms, and the tradeoffs involved when implementing such mechanisms in 802.16 mesh mode, focusing on the efficient management of the available bandwidth resources. In order to evaluate and validate the performance of the developed mechanisms, a simulation study is being developed, based on the NS2 and NCTUS simulation tools. 151 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Home networks and residential gateways – The constant evolution of the home network solutions/equipments (HGWs and STBs included) obliges also a continuous research and learning effort. Manufactures of Home Network solutions, alternatives to the UTPcat5e structured network, for the existing home transport medium (air, electric, coaxial, phone networks) are making evolutions that are been testing (e.g. PLC, Wi-Fi, HPNA). The results of the research and experimentation of different equipments/solutions obtained are enabling high knowledge recognition on this “Home Networking” technologic area. On example of that is the collaboration with PTCom on the equipment’s technical specifications for the commercial Triple-Play deployment (meo) and respective conformity tests support. The evolution of the current used HGW for the PTCom commercial TriplePlay service (meo) will be the introduction of a "middleware" in this equipment which allows the life cycle management of new personalized services. In the market there are many alternatives (e.g. OSGi, HAVi), but still under development or in commercial products with a lack of maturity, not allowing operators to invest these new approaches as part of their trading platforms. The existing knowledge on OSGi obtained by the participation on different IST projects (e.g. IST@Home, MUSE) allows the current work on this technology. The current development of an OSGi platform promotes the development of an innovative support for advanced and innovative residential services controlled by the operator PTCom. Another complementary objective of this activity is the design of an OSGi test suite. Heterogeneous networking issues - Research has been performed in heterogeneous networks, focused on the evolution towards fixed and mobile, convergent, next generation architectures. This work covered areas of: QoS support across different technologies and networks (infrastructure and ad-hoc) and over different administrative domains; mixed mobility types with QoS integration and mobility management in multi-access environments, using IEEE 802.21 to support media independent handovers, and mechanisms for intelligent handover decisions commonly performed by the user and network (specific technologies supported: Ethernet, 802.11, 802.16, DVB and 3G); multicast communications with QoS and mobility; mobility of both mobility of the listeners and of the sources in multicast environments, where the movement of sources is made transparent to the receivers; real-time bidirectional communications in unidirectional technologies (DVB), making use of a different technology return channel, covering aspects of QoS and mobility; and privacy support using virtual identities and identity based 152 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA mobility. New developments are being addressed in the integration of LTE with these architectures, specifically addressing mobility and QoS. Context-aware multiparty session - In future scenarios, context-aware services and multicasting will together drive a new trend, since context-awareness can exploit situations in which users share the same interests and request similar services, increasing the effectiveness of session and network control. In these environments, where groups may be created based on context, multicast takes a new lead to the communications environment. However, context-aware networks also introduce personalized concepts: any change to context, such as, location, mobility, velocity, preferences, presence, can change the overall services and network environments, requiring the network and multicast sessions to be completely restructured in a very dynamic way. This dynamicity poses scalability problems in current networks. We proposed an efficient architecture for contextaware multiparty session and network control which dynamically adapts to contexts’ and networks’ dynamics and maintains the connectivity with the expected requirements over session lifetime. We consider the concepts of dynamic session and network control, driven by context, but introduce the concept of abstract trees in the network to increase the stability of the network to any context change. Security and Quantum Information Joint Compression and Security. For some decades secure communication systems have been employing a modular approach to security. These systems usually perform encryption using conventional cryptographic primitives that are insensitive to the characteristics of the communications channel, relying on mathematical operations assumed to be hard to compute, such as prime factorization and the discrete logarithm function. They do not take into account the specificities of the data being encoded nor some essential mechanisms for data transmission such as quantization and data compression. For applications with realtime constraints it is important to minimize the computational overhead introduced by the use of cryptographic primitives. This minimization could be achieved by relying on specif properties of the transmitted data and the underlying communication system. In particular, coding techniques have been shown to allow reliable and efficient encryption. Using intelligent coding procedures we can design lightweight secure protocols that introduce little overhead to the encryption. In this 153 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA line of research we propose the use of coding techniques to perform lightweitght encryption. Our contribution focuses on two different buiding blocks of a communications system. First, we rely on quantization as a means of obtaining security. Secondly, we develop cipher mechanisms, that perform an analysis of the output of the source coder to compute a keystream used in encryption of the source messages. Soundness and completeness of formal encryption - In their seminal work, Abadi and Rogaway show that the formal (Dolev-Yao) notion of indistinguishability is sound with respect to the computational model: pairs of messages that are indistinguishable in the formal model become indistinguishable messages in the computational model. However, this result has two weaknesses. First, it cannot tolerate key-cycles. Second, it makes the too-strong assumption that the underlying cryptography can hide all aspects of the plaintext, including its length. Both of these weaknesses stem from a ’gap’ between the formal and computational models, and we consider and close both weaknesses in this paper. It is shown that the recently-introduced notion of KDM-security can provide soundness even in the presence of key- cycles, which is the first time a gap has been closed by strengthening the computational model. Encryption that reveals the length of plaintexts is considered, and it is used to motivate a general examination about information-leaking encryption. In particular, the conditions under which an encryption scheme , which may leak some partial information, will provide soundness and completeness to some (possibly weakened) version of the formal model. Improving authentication schemes with quantum information - The problem on how quantum resources can improve the security of authentication protocols has been addressed. The starting point is the protocol introduced by Brassard in 1983. In that protocol, the shared key is the seed of a pseudo-random generator (PRG) and a hash function is used to create the authentication tag of a public message. It was shown that a quantum encoding of secret bits offers more security than the classical XOR function introduced by Brassard. Furthermore, we proof that quantum resources can simultaneously improve both secrecy of the key generated by the PRG as secrecy of the tag obtained with a hidden hash function. Moreover, the proposed quantum protocol can be also used in order to authenticate the quantum channel itself. 154 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Farness constrains for the Dolev-Yao attacker - Fairness constraints for the Dolev-Yao attacker, when checking liveness properties, were investigated. It was showed that any fairness constraint that makes the standard Dolev-Yao attacker sound w.r.t. an (honest) buffer, under the fair scheduling constraint, is a nonregular property. Design of new security protocols - A fair contract signing protocol was propose using quantum tamper-proof devices. In the proposed protocol the signing agents do not need to communicate with a third trusted party during the signing phase, which has been proved to be impossible using only classical information in asynchronous networks. The protocol relies on decoherence of quantum information to encode a global clock that works as a synchronization mechanism. The protocol can be implemented with existing quantum technology. Attacker with cryptanalytical capabilities - A probabilistic model for the analysis of security protocols was purposed. The proposed model allows one to reason about attackers that extend the usual Dolev-Yao adversary with explicit probabilistic statements representing their (partial) knowledge of the properties of cryptographic primitives. An entropy-based approach was developed to estimate the probability of a successful attack on a cryptographic protocol given the prescribed knowledge of the attacker. This quantity was shown to be NP-hard to compute, but it is useful to analyze a few practical examples. Commitment and authentication - A question raised in the paper Constructions and Bounds for Unconditionally Secure Non-Interactive Commitment Schemes, by Blundo et al., 2002, was answered and it was shown that there is a close relation between unconditionally secure commitment schemes and unconditionally secure authentication schemes. Moreover it was also shown that an unconditionally secure commitment scheme can be built from such an authentication scheme and an unconditionally secure cipher system. Traffic Engineering Traffic engineering of Ethernet networks - In this activity, we address the problem of how to use the IEEE 802.1S Multiple Spanning Tree Protocol (MSTP) to improve load balance, service disruption and survivability of Metro Ethernet networks. We are pursuing two different sets of traffic engineering problems. In the first set, we are defining optimization models and developing suitable solving 155 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA techniques able to obtain optimal solutions. In particular, we have already published different models and solution techniques, based on Dantzig-Wolfe decompositions, to solve optimally different objective functions related to optimal network load balance. A conference paper was published in proceedings of INOC 2009, Pisa, Italy. This activity is being conducted in collaboration with Prof. Filipe Alvélos (Escola de Engenharia, Universidade do Minho). In the second set of problems, we are conducting collaboration with Prof. Michal Pioro (University of Warsaw, Poland) in order to deal with the min-max optimization of link loads, using the polish previous work on max-min fairness. A conference paper was published in proceedings of NGI 2009, Aveiro, Portugal (published in IEEE Xplore) and a journal paper was submitted in 2009 and accepted for publication in 2010 in Telecommunication Systems (Springer). Traffic engineering of MPLS networks – The traffic engineering problem was addressed aiming to minimize the routing hop-count while guaranteeing network survivability based on multiple disjoint paths. A conference paper was published in proceedings of INOC 2009, Pisa, Italy and a journal paper was submitted in 2009 and accepted for publication in 2010 in International Transactions in Operational Research (Wiley-Blackwell). This activitiy has been done in collaboration with Prof. Luis Gouveia (Departamento de Estatística e Investigação Operacional, Faculdade de Ciências, Universidade de Lisboa). Minimum interference routing algorithms – Minimum interference routing algorithms aim to reduce the rejections rate of future requests for the establishment of bandwidth guaranteed paths (such as MPLS LSPs). They are intended to be used in online traffic engineering and, therefore, they make no assumption regarding future request arrivals. We have conducted a throughout analysis of several minimum interference routing algorithms and introduced novel scenarios to simulate these algorithms. We have analyzed the suitability of these routing algorithms to scenarios where demands are bidirectional and to scenarios where 1+1 protection may be required. Then, we have developed a new algorithm, named, Minimum Interference with K-Shortest Paths Identification, that exploits the possibility of reducing not only the interference when routing new demands but also protecting the maximum unsplitable bandwidth path. This work was done under the dissertation of a Professional Master in Information Networking (MSIN) between University of Aveiro and Carnegie Mellon University. 156 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Detection of Internet applications - We have developed a statistical method to identify Internet applications that (i) selects the flow features that are stable across traffic traces, both in time and space, resorting to the so-called effect size, and (ii) performs classification based on the principal components of the (stable) flow features. Application of the method was carried out on traffic traces of Orange (France Telecom) network. We have also explored the use of multi-scaling traffic analysis for the same purpose. Detection and characterization of P2P Internet applications - Peer-to-peer file-sharing systems have gained tremendous popularity in the past few years. The traffic generated by P2P systems, and particularly BitTorrent, represents the major portion of the global Internet traffic, largely overtaking the traffic share of the World Wide Web. More users are continually joining such systems and more objects are being made available, seducing even more users to join. An accurate mapping of traffic to their applications can be very important for a broad range of network management and measurement tasks including traffic engineering, service differentiation, performance/failure monitoring, and security. Traditional mapping approaches have become increasingly inaccurate because many applications use non-default or ephemeral port numbers, use well-known port numbers associated with other applications, change application signatures or use traffic encryption. We developed two new identification methodologies, one based on neural networks and other based on principal component analysis. Both methodologies are able to identify flow patterns generated by P2P Internet applications while overcoming the limitations of existing approaches. The results obtained show that, when conveniently utilized, both methodologies constitute a valuable tool to identify P2P Internet applications since they are able to achieve good performance results while, at the same time, avoid the most important disadvantages presented by the other identification methods. Nowadays, we see P2P systems evolving towards a Video on Demand (VoD) platform. One of the main challenges of these systems is to efficiently share data in the dynamic and continuously evolving Ad-Hoc networks of users. This ability heavily depends on the peers' locations and characteristics on this type of networks. Therefore, it is important to identify and characterize the usage profiles of such P2P application. Towards that objective, we used the current BitTorrent system to evaluate the peer-level characteristics of users sharing video contents. These characteristics include geographical location, peers availability and peers “distance”, measured in terms of the round trip time. From the results 157 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA obtained, we conclude that peers sharing video content present some unexpected locality features that, if conveniently exploited, could greatly benefit VoD P2P systems both in technological and service marketing terms. Detection of network intrusions and anomalies - The detection of network compromised hosts is currently performed at the network and host levels but any one of these options presents important security flaws: at the host level, antivirus, anti-spyware and personal firewalls are ineffective in the detection of hosts that are compromised via new or target-specific malicious software while at the network level network firewalls and Intrusion Detection Systems were developed to protect the network from external attacks but they were not designed to detect and protect against vulnerabilities that are already present inside the local area network. We presented a new approach for the identification of illicit traffic that tries to overcome some of the limitations of existing approaches, while being computationally efficient and easy to deploy. The approach is based on neural networks and is able to detect illicit traffic based on the historical traffic profiles presented by "licit" and "illicit" network applications. The evaluation of the proposed methodology relies on traffic traces obtained in a controlled environment and composed by licit traffic measured from normal activity of network applications and malicious traffic synthetically generated using the SubSeven backdoor. The results obtained show that the proposed methodology is able to achieve good identification results, being at the same time computationally efficient and easy to implement in real network scenarios. Network modeling for performance prediction - Wired and wireless network traffic exhibits peculiar and unpredictable behaviors that can be attributed to the combination of different factors: the varying number of users, the capacity of the network access links/points, network traffic matrices, users' mobility, background traffic, diversity of applications, services and user behaviors. This scenario creates an increasing need for tools that can cope with the continuous appearance of new applications and QoS requirements and is able to aid in the global management tasks of IP networks. We proposed an integrated management framework for wireless and wired networks that utilizes the network models based on neural networks previously developed and a new set of procedures allowing (i) to predict network Quality of Service (QoS) evolution for varying number of users and user characteristics and (ii) to assess the need for network upgrades. Additionally, the research team have started the evolution of the network models based on neural 158 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA networks towards a integrated Markovian based model able to jointly characterize users' behaviours and network characteristics and predict network performance in future operational scenarios. Congestion control in packet networks – We researched congestion control in heterogeneous links, following an end-to-end approach. This has been one of the hot research topics in the networking community, where alternatives to currently deployed versions of TCP have been discussed and tested. The objective is to improve both the performance in high speed links and the efficiency of TCP congestion control procedures. Currently, several TCP versions (under testing) can already be found in different operating system distributions. We have been testing (within a MSc work) some existing solutions and discussing alternatives for implementation in high-speed networks in the presence of significant delays (i.e. large bandwidth-delay product links). In addition to the previous topic, we have been involved in the more specific research of congestion control in wireless links. Although some of the TCP versions that have been proposed to improve the performance in heterogeneous links may also work better in wireless links, there are particular characteristics in wireless links that have been considered: the high error rate and the difficulty in distinguish between error losses and congestion losses. We have been looking for end-to-end solutions to these problems. We also researched congestion control in the Internet, following a router-assisted approach. Although much more difficult to deploy (because it requires the cooperation of all routers in the path, as well as the destination), this approach has shown better results in terms of stability and performance than the end-to-end approach. In addition to the modeling and stability assessment of router algorithms, we have been looking at alternative and effective congestion signaling schemes based on explicit binary marking, for the control of window-based and rate-based sources. Network Operations, Management and Planning In-Network management - Self-adaptation in the scope of in-network management is the capability of each node (and therefore of the network), to react to changes insuring the proper network behavior, according to the defined management policies. INM applications such as real-time monitoring and situationawareness provide state and context information to the decision processes within the self-adaptation applications. The optimization includes the support of local 159 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA resources optimization (through predictive approach) and reconfiguration, accessnetwork selection and assisted routing (as optimal path selection). These functions require the ability to discover the nodes, perform network bootstrap, and manage entry/leave nodes. In this work we started the specification process of the selfadaptation mechanism to support in-network management, considering the information that needs to be transferred between nodes and the decision process. We are currently studying and applying game theory and Bayesian networks to support this cooperation process. Cross-layer measurements - Service Performance Evaluation is usually associated with connectivity related services, such as the provisioning of an internet connection. Now operators are beginning to explore new business opportunities on the All-over-IP world and beyond. New solutions are being deployed focusing on the multimedia interactive contents. New network architectures will require extensions to provide a clear vision on the service delivery quality, and new approaches on cross-layer information will be envisioned. This work provides an insight on the cross-layer overview of the current 3GPP networks, while featuring the analysis until the end-to-end performance and end-user perception. It employs a correlation between the most relevant parameters at each layer and underlines their contribution to the upper layers. It further provides an analytical qualitative analysis of the overall service performance by evaluating simulation results which are sustained by both network and service performance metrics. Network Applications and Services Network virtualisation – We have built a small-scale network virtualisation testbed, based on XEN technology, where key features of network virtualisation can be demonstrated: on-demand creation, reconfiguration and elimination of virtual networks; migration of virtual resources; auto-discovery of physical and virtual resources. An additional result of this activity will be a network virtualisation management system, to provide the network infrastructure owner with the capability to enforce virtual resource management policies. The ultimate goal of this activity is the demonstration and evaluation of the concept of network virtualisation from the perspective of a network provider. Identity Management – Motivated by the actual demand for identity and privacy management, we have built an user-centric Identity Management prototype that 160 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA incorporates the major state of the art technologies. In future scenarios and networks, Identity management plays a key role for service composition and service/network integration (vertical integration). To demonstrate future network scenarios, the prototype was integrated with NGN network functions, enhanced it with a new identity layer that provides a user-centric way to integrate Telco with Web2.0 services. Personal Smart Spaces (PSSs) – Development of PSSs that provide a minimum set of functionalities which can be extended and enhanced as users encounter other smart spaces during their everyday life. Unlike isolated smart spaces (such as smart homes) these PSSs will be capable of learning and reasoning about all kinds of users their intentions, preferences and context. They will endowed with proactive behaviours which enable them to share context information with neighbouring PSSs, resolve conflicts between preferences of multiple users, make recommendations and act upon them, prioritise, share and balance limited resources, services and devices, reason about trustworthiness to protect privacy and be sufficiently fault-tolerant to guarantee their robustness and dependability. The communication between PSSs in a peer-to-peer mode is over JxTA and the service platform that supports several service enablers, as for example the group manager and resource sharing, is an OSGi Open Platform. Context framework and context-aware service enablers for multicast content delivery– Development of a global context-aware framework specifically intelligent for multiparty services. This framework will allow the mediation and aggregation of context information coming from a large number of sources and types of context providers (e.g. operator context providers as location, Internet providers as Facebook and private context providers as for example Wireless Sensor Networks). A context broker will be the access point for context-aware applications and services to access raw and inferred context information. This Framework will also include the design and develop of context-aware service enablers specifically for delivering content in multicast-broadcast environments; dynamically create and modify groups, intelligently select content, automatically set-up, modify multicast sessions and allocate network resources are some of the important functionalities provided by this service enabling platform. Integration of this framework with already existing platforms and/or components (as for example IMS, TISPAN RACS,...) will also be provided. The main objective of this work is to 161 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA evolve multimedia multicasting to exploit the increasing integration of mobile devices with our everyday physical environment. Mobile and Ubiquitous Computing - In the area of mobile and ubiquitous computing we proposed a new system for fall detection and automatic notification, using a regular PDA with an accelerometer and GPS. This system is designed for being used both inside hospital and in a regular daily life of senior people. Another proposal is the MP-Collaborator, a mobile collaboration tool in pervasive environment. It was created to improve and optimize the communication between collaborators in any organization. MP-Collaborator draws information from location, user status and Pocket Outlook Calendar to create a user availability profile, which is published to any other user in the network. Based on availability status, the user can be reached using a simple phone call ora message. Through the opportunistic use of available mobile technologies MP-Collaborator provides a simple but critical service - user presence service. Processing, Analysis and Coding of Audio and Visual Information Distributed video coding – During 2009, we continued to have distributed video coding as its main activity in the video coding area. The main topics addressed were: 1. Definition of efficient encoder rate control solutions for transform domain DVC, thus avoiding a feedback channel to perform efficient rate control. 2. Motion compensated frame interpolation (MCFI) is one of the most efficient solutions to generate side information (SI) in the context of DVC. However, it creates SI with rather significant motion compensated errors for some frame regions while rather small for some other regions depending on the video content. In this context, a low complexity Intra mode selection algorithm has been developed to select the most ‘critical’ blocks in the WZ frame and help the decoder with some reliable data for those blocks. 3. Characterization of the DVC coding efficiency when motion compensated frame interpolation (MCFI) techniques are used to generate the side information. An efficiency analysis of motion interpolation side information estimators has been performed using a DVC compression efficiency rate model relating the power spectral of the estimation error to the accuracy of the MCFI motion field. 162 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA 4. In a feedback channel based DVC architecture, the high decoding complexity is mainly due to the Slepian–Wolf decoding and the repetitive request-decode operation, especially when there is no initial encoder rate estimation or iterative motion refinement is employed. In this context, an early stopping criterion for the LDPC syndrome belief propagation decoder has been developed that is able to reduce the number of decoding iterations. 5. While state-of-the-art DVC codecs have shown promising RD performance, most DVC codecs in the literature do not consider low delay requirements which are relevant for some of the addressed applications. In this context, an efficient, low delay and fully practical DVC codec based on the Stanford DVC approach has been developed. 6. To improve the turbo coding performance in the context of DVC, a probability flipping approach acting as an outer loop of the common turbo decoding operation has been developed. Whenever a turbo decoded bitplane is not error-free, the proposed method tries to correct bitplane errors by iteratively refining the a priori data for the most likely in error bit positions, followed by turbo re-decoding. Perceptual video coding: In this topic, the work carried out in 2009 focused on: 1. Study of spatial visual just noticeable distortion models for integration in a H.264/AVC standard codec to improve the final rate-distortion performance. Three masking aspects related to lossy transform coding and natural video contents have been considered: frequency band decomposition, luminance component variations and pattern masking. 2. Decoder side estimation mechanism for a just noticeable distortion perceptual model integrated in a H.264/AVC codec to improve its RD performance. The proposed estimation avoids having to send the perceptual weights used during the quantization of each frequency coefficient. Video Transcoding and Scalability - In the topic of video adaptation/transcoding, we developed fast methods to adapt H.264/AVC video streams from high spatial resolution to mobile terminals. The research in flexible video coding using scalability was focussed on scalable coding of video summaries with arbitrary temporal rates in two layers. Rate control – In 2009, research on how to efficiently combine error resilience and rate-control techniques for frame-based video coding systems, such as those based 163 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA on the H.264/AVC video coding standard, was continued. A method for efficiently and automatically taking into account the packet loss rate of the network when performing coding mode decisions for video transmission was developed. With this method, the generated H.264/AVC bitstreams are both efficient and are perfectly adapted to the channel error characteristics. We have also worked on Automatic and adaptive error resilient rate-control techniques for frame-based video coding systems that are able to adapt the encoding decisions to the network error conditions (e.g., packet loss rate) and the available bit rate. Quality evaluation - Continuing the work started three years ago, during 2009 research has been focused on no-reference, objective metrics for quality evaluation of video sequences, subject to lossy encoding (MPEG-2 and H.264/AVC) and transmission errors (packet losses). A new perceptual metric for the quality estimation of H.264/AVC encoded sequences, has been developed. Video error resilience - In 2009, research on how to efficiently combine error resilience and rate-control techniques for frame-based video coding systems, such as those based on the H.264/AVC video coding standard, was carried out. The major achievement was the proposal of a method that efficiently and automatically takes into account the packet loss rate of the network used for video transmission when performing coding mode decisions at the encoder. This method can be used to efficiently generate error resilient H.264/AVC bitstreams that are perfectly adapted to the channel error characteristics. Medical Image Analysis - Our research addresses how computer vision may be a key factor for developing automated or semi-automated computer assisted decision systems for gastroenterology. We have also worked on assisted annotation of microscopy imaging. Biology laboratories produce massive amounts of microscopy data, which typically takes days to manually process. Computer vision, along with other research fields such as Human-Computer Interaction, can pave the way for what is currently known as high-throughput microscopy imaging: full automation of the imaging capture and analysis process, significantly boosting Biology research. We have carried out research on breast cancer detection, focusing in the following topics: utilization of high performance cluster computing technologies for paralell 3D/4D medical image processing (jointly performed with Microsoft Portugal); development of new approaches for early diagnosis and prevention of breast cancer 164 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA through computer aided diagnosis (jointly performed with Siemens); analysis of ultrasound images and case studies regarding breast cancer (jointly performed with the School of Health Sciences, UBI). Medical Signal Analysis – We have address state-of-the-art digital audio signal processing research challenges for extracting clinical features from auscultation, as well as providing a clinical second opinion on specific heart pathologies. We pay particular attention to aortic pulmonary signal decomposition and its correlation with pulmonary arterial pressure, researching novel algorithms that can enable us to assist clinicians in the detection of pulmonary arterial hypertension situations. The goal of the CMU|Portugal Vital Responder research project is to explore the synergies between innovative wearable technologies, scattered sensor networks, intelligent building technology and precise localization services to provide secure, reliable and effective first-response systems in critical emergency scenarios. Using Vital Jacket® technology, our research team works on signal processing and human-computer interaction tasks. Computer Graphics - A new oversimplified geometric data structure for applications in computer games, virtual reality, and computer graphics was developed. A new algorithm for the simulation of fluids (for applications in computer games, virtual reality,and computer graphics) was introduced, based on a simplified version of the Navier-Stokes equations and a Gauss-Seidel red-black scheme. This algorithm runs on both CPUs and GPUs and is a 3D variant of Stam's stable fluids that runs on GPU using CUDA technology. We have developed a high-performance GPU-based algorithm for triangulating and rendering biomolecules for molecular modeling. We have designed and implemented a 3D graphics library for the web without the complexity of the X3D technology or any add-ons. The graphics library runs directly on the browser. We have proposed an engineering software principle to easily turn a multiplayer FPS (first-person shooter game, like Quake) into a massively multiplayer online FPS game using grid technology. This is in progress in order to build an API for building FPS games on a grid. Image Restoration – We have proposed a new approach to handle non-additive noise models (namely multiplicative and Poissonian) in image recovery problems. Our approach uses two main building blocks: variable splitting, yielding a 165 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA constrained optimization problem; handling this optimization problem using an augmented Lagrangian method. We show that the resulting algorithms are instances of the alternating direction method of multipliers and that the conditions guaranteeing its convergence are satisfied. Experiments show that our approach yields state-of-the-art performance. Another topic of research concerned fast algorithms for the optimization problems resulting from sparsity-inducing regularization to imaging inverse problems (including compressive sensing). In this context, we have introduced new algorithms of the augmented Lagrangian family, which achieve state-of-the-art performance. Calculus and Languages for Sensor Networks - Sensor networks are rather challenging to deploy, program, and debug. Current programming languages for these platforms suffer from a significant semantic gap between their specifications and underlying implementations. This fact precludes the development of (type-)safe applications, which would potentially simplify the task of programming and debugging deployed networks. In this paper we define a core calculus for programming sensor networks and propose to use it as an assembly language for developing type-safe, high-level programming languages. Assisted Analysis of Cellular Images - Biology research laboratories such as IBMC (Instituto de Biologia Molecular e Celular) produce a large quantity of microscopy images that need to be analyzed. An example of an analysis is to count the number of cells and parasites in a given image to infer the infection level. In most situations, this analysis is performed entirely manually by the researchers themselves or by people hired specifically for this purpose. This manual analysis has some drawbacks: it is a slow procedure, since its made by humans, its prone to errors (by a number of factors such as counter’s fatigue, stress, etc), and recounting is crucial for reliability of the analysis. Another important factor in manual counting is that in some cases it can lead to seasickness of the person doing it, since he is looking at a moving scene, his brain process this information as if he is also moving but, another hand, getting in conflict with the signals from the inner ear, that’s saying he is not moving. To overcome these limitations it is necessary to eliminate the human factor, reduce the costs and the time spent in this kind of tasks. This can be achieved by automating the entire process.Therefore, we are developing a software that it will analyze automatically a given set of cellular images using state-of-the-art image processing algorithms. 166 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Digitally enhanced stethoscope for clinical usage - The DigiScope project involves signal processing (clinical feature extraction), data mining (pathology detection using audio features and patient record information) and the ability to not only collect heart audio signals, but also to extract patient record information by communicating directly and efficiently with typically heterogeneous and complex hospital information systems. We argue that the key to robust solutions lies in a stronger interaction with the clinical community, both for understanding the needs of cardiologists and robust clinical validation of the methods and of the final prototype. The main constituents of a cardiac cycle are the first heart sound (typically referred to as S1), the systolic period, the second heart sound (S2) and the diastolic period. Whenever a clinician is performing an auscultation, he tries to identify these individual components, and is trained to analyze related features such as rhythm, timing instants, intensity of heart sound components, splitting of S2, etc. Currently, an infrastructure composed by an integrated electronic patient record system, auscultation storage and retrieval system (all developed by our team), is running on the Royal Portuguese Hospital in Pernambuco-Brazil, having a team of physicians collecting patient data and auscultations and storing them on the IT’s server. A System to Re-Use Facial Rigs in Animations - Facial animation in films and videogames are strongly dependent on a fixed rig that is custom created for each character. The rig is defined in the early stages of the development and is conditioned by the characters morphology. We present a portable character rigging system that integrates into current animation production pipelines enabling digital artists to create more lifelike characters in less time about 90-99% faster, when compared to traditional animation techniques. It automatically transfers the rig and animations created in one character to different characters, independent of their shape and appearance. Artists are not forced to use predefined rigs and can preserve the original mesh they created. As a result, the system improves the workflow in CG productions, the modeling and animation teams can now work in parallel. Pattern Recognition and Automatic Learning Biometrics – We continued our work on the development of a non-cooperative multimodal recognition system. Work was done in robust iris image segmentation and face recognition in the visible wavelength. 167 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA The use of distributed source coding concepts and hash functions to secure biometric data was investigated. This new approach makes it possible to generate many different templates from the same biometric data, which can be canceled if they are compromised. Furthermore, it also guarantees that the original biometric data cannot be recovered from the stored data, thus guaranteeing its privacy. We have started to investigate new approaches to using the one-lead electrocardiogram (ECG) signal as a biometric, both for authentication and identification. Classification methods – A new criterion based on the use of the minimum entropy of the error for building decision trees was proposed. For reservoir networks, a method was proposed to make possible the use of these recurrent networks for static pattern recognition problems, the proposed method was benchmarked in 25 standard pattern recognition problems and a study of the influence of the main model parameters was done. Compression Based Classification – In 2009 we have continued to work on text classification methods based on lossless compression algorithms of the Lempel-Ziv family. Most approaches to text classification rely on some measure of (dis)similarity between sequences of symbols. Information theoretic measures have the advantage of making very few assumptions on the models which are considered to have generated the sequences, and have been the focus of recent interest. In this line of work we have used the Ziv-Merhav method and the Cai-Kulkarni-Verdú methods for the estimation of relative entropy from sequences of symbols, with excellent results in authorship attribution tasks. Clustering – Exploiting the notion of Evidence Accumulation Clustering (EAC), and a resampling-based cluster stability measure, we have continued to work on the problem of learning similarities from data. The developed similarity learning method was shown to have state-of-the-art discriminatory capacity and to better revela the intrinsic cluster structure of the data. We also explored combination techniques based on the EAC paradigm, but with different weighting of the clusterings using quality measures. Fusion techniques from supervised and unsupervised learning (classifier fusion and cluster ensemble methods) were exploited simultaneously in the problem of features selection, yielding new promising techniques. Information Theory and Estimation Theory – we have carried out research on the intersections of information theory and estimation theory and their applications 168 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA in the analysis, design and optimization of communications systems and in physical-layer security. Speech Analysis – We have investigated the representativeness of the coarticulation phenomenon in European Portuguese and described its regular characteristics. The results will allow setting up models to reconstruct graphemephone conversion rules for Portuguese multi-pronunciation speech systems. 169 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA 4.3.4 Running and Concluded Projects Overview Number Funding Agency DAAD 1 DoCoMo 1 EU-FP7 7 Euro-NF internal, European Commission 3 European Science Foundation 1 FCT 4 FCT/CAPES 1 FCT/PTDC 7 QREN/Telecom Inovação 1 FLAD 2 GRICES 1 GRICES-CNRS 1 Instituto de Telecomunicações 8 National Science Foundation - QREN 2 Polytechnic Institute of Leiria 1 Projecto Europeu do 6º Programa Quadro 1 projecto interno da Rede de Excelência do 7º Programa 1 Quadro Euro-NF PT Inovação 1 Treat of Windsor - BritishCouncil/CCISP 1 Total 45 Table 24 – Number of active projects in the Networks and Multimedia Area during 2009 170 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Activity in Projects Acron / Ref AVATAR Title 3D Face Animation Funding QREN Descript. Project AVATAR aims to develop 3D animated face models that are synchronized with speech. The input to the system can be either speech or text. In the case of speech input, a recognizer is used followed by a converter from phonemes to visemes. In the case of text input, a synthesizer is used to create both the audio (speech) and the sequence of visemes. 3D face animations, created after the sequence of visemes, need to run on browser to allow the development of rich and interactive WEB applications. The project is funded by QREN where IT participates as a subcontractor. Acron / Ref Affective Mouse Title Affective Mouse Funding National Science Foundation - QREN Descript. This project aims at determining the role of emotions on the learning process and the way in which these can influence the results of the process. The goal is to develop a Human-computer interaction device (which is envisioned as a computer mouse) that measures multiple electrophysiological signals from the children and simultaneously allows the interaction with a multimedia Web application with games and educational exercises. Thus we want to know how different activities influence the physiological signals while completing the exercises/games on the Web platform. The system will allow the tutor to follow-up the learning process, adopt incentive measures, and adjust the learning 171 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA process according to the emotive signals of the children. As a result of the R&D project a physiological signal database will be produced on didactic and cognitive exercises, this way creating a base structure for advanced studies in affective computing and real interaction/learning environments. Acron / Ref Title OneLab2 An Open Federated Laboratory Supporting Network Research for the Future Internet Funding EU-FP7 ICT Descript. Experimentally driven research is key to success in today’s Internet. Many test beds support research and development, and product prototyping in communication networks. However, they tend to specialise in particular access technologies or services, or explore near term product offerings, often with limited availability and openness. An open and sustainable large-scale shared experimental facility will allow European industry and academia to innovate today and to design the future Internet. The OneLab2 project will leverage the original OneLab project’s PlanetLab Europe test bed and its international visibility to make this facility a reality. OneLab2 is built on three complementary pillars. The Platform Pillar will operate PlanetLab Europe, extending PlanetLab service across Europe, and federating with other PlanetLab infrastructures worldwide. It will integrate new features into the system. The Tools Pillar will enhance the test-bed-native network monitoring service that supports experiments. And the Customers Pillar will meet the needs of the facility’s customers by providing them with access to diverse facilities, achieved through federating different types of test bed. An experimental facility must know its customers. OneLab2 will do this by directly involving pilot customers who are testing novel ideas in networking research. 172 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Acron / Ref Title Future-COM Analysis, Design and Optimization of Future Communications Systems From Theory to Practice Funding IT Descript. The main objective of the research project FUTURE-COM: Analysis, Design and Optimization of Future Communications Systems: From Theory to Practice is to explore a novel framework based on the interplay between information theory and estimation theory in the analysis, design and optimization of communications systems with relevance in practice. The advent of the information age has also been igniting the development of a whole telecommunications infrastructure to support the ubiquitous access to the Internet at ever increasing information rates. The last decade has in fact witnessed an exponential growth in wireless communications systems and services, e.g., 2nd and 3rd generation systems as well as WiFi and WiMax, with this revolution being fuelled by constant technological breakthroughs to enhance transmission performance over the wireless medium. The discipline of information theory has been constantly at the heart of this revolution, since it establishes the fundamental limits of communications systems. Yet, the presence of complex communication system features often precludes system design in a rigorous information-theoretic way due to the lack of appropriate mathematical tools, with system designers often resorting to engineering experience and insight. We propose a different approach: the analysis, design and optimization of communications systems based on connections between the key quantities in information theory and estimation theory. The expected outcomes of this two-year collaborative research project are: i) essential theoretic and practical methodologies to design enhanced communications systems in a rigorous information theoretic way; and ii) novel technical solutions to optimize current telecommunications systems, including WiFi, WiMax and LTE wireless networks, as well as digital subscriber line (DSL) networks. Our research team gathers considerable expertise in a wide range of complementary topics such as information theory, estimation 173 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA and detection theory and communications systems and networks, all of which are necessary to meet both the theoretical and practical challenges of this research. High level publishable and patentable results are expected. Acron / Ref EURO-NF Title Anticipating the Network of the Future Funding EU, 7º Programa Quadro Descript. arquitecturas de redes heterogéneas e monitorização de Qualidade de Serviço e avaliação do estado das redes IP Acron / Ref SIMBAD Title Beyond features: similarity-based pattern analysis and recognition Funding EU-FP7 ICT Descript. The challenge of automatic pattern analysis and recognition (or machine learning) is to develop computational methods which learn to distinguish among a number of classes from examples, with a view to endow artificial systems with the ability to improve their own performance in the light of new external stimuli. This ability is instrumental in building next-generation artificial cognitive systems which, as opposed to traditional machine or computer systems, can be characterized as systems which cope with novel or indeterminate situations, which aim to achieve general goals as opposed to solving specific problems, and which integrate capabilities normally associated with people or animals. The socio-economic implications of this scientific endeavor are enormous, as it will have applications in a wide variety of real-world scenarios ranging from industrial manufacturing to vehicle control and traffic safety, to remote and on-site (environmental) sensing and monitoring, and to medical diagnostics and therapeutics. This project aims at bringing to full maturation a paradigm shift that is currently just 174 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA emerging within the pattern recognition domain, where researchers are becoming increasingly aware of the importance of similarity information per se, as opposed to the classical feature-based approach. Indeed, the notion of similarity has long been recognized to lie at the very heart of human cognitive processes and can be considered as a connection between perception and higher-level knowledge, a crucial factor in the process of human recognition and categorization. We shall undertake a thorough study of several aspects of purely similarity-based pattern recognition methods, from the theoretical, computational, and applicative perspective. We aim at covering a wide range of problems and perspectives, considering both supervised and unsupervised learning paradigms, generative and discriminative models, and our interest will range from purely theoretical problems to real-world practical applications. We shall apply our algorithms to challenging biomedical problems that lend themselves particularly well to similaritybased approaches, namely, to the analysis of tissue micro-array images of renal cell carcinoma and to magnetic resonance brain imaging for the diagnosis of mental illness. Acron / Ref BLEP / PTDC/DES/72946/2006 Title Biomechanics of Locomotion in Elderly People Funding FCT/PTDC Descript. The project has the main objective of developing a set of experimental tools for the study of the risk of fracture in elderly people. The risk of fracture is related to the risk of fall and to bone resistance. The aim of this study is to develop a risk profile that can be used to identify community-residing elderly at high risk of falling and to establish strategies to prevent falls in healthy older adults and to identify the variables associated with an increased risk of falls and fractures. The use of advance clustering techniques for data reduction should allow the identification of the relevant variables for kinematics and kinetics parameters that are fundamental for the maintenance and development of the balance and locomotion skills of daily live in elderly population 175 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA and also to identify high-risk groups for falls and fractures. The results of the questionnaire assessment, field tests and laboratory studies should allow the establishment of guidelines for the development of exercise and perceptive training programs.

One of the main goals of this project is to develop a solution supporting the generation of different templates from the same biometric and thus supporting cancelable biometrics.

For this purpose, not invertible hash functions will be used together with concepts from distributed source coding. Acron / Ref Title CALLAS Calculi and Languages for Sensor Networks 176 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Funding FCT/PTDC Descript. The main goals of the CALLAS (Calculi and Languages for Sensor Networks) research project are: to contribute towards a fundamental understanding of wireless sensor networks by developing formal tools based on process calculi; to provide adequate programming architectures for dynamically configurable sensor nodes; and to validate the proposed designs in real-life prototype sensor applications. Wireless sensor networks, made of tiny, low-cost devices capable of sensing the physical world and communicating over radio links, are significantly different from classical wireless networks such as GSM or wireless LANs: (a) the design of a sensor network is strongly driven by its particular application, (b) sensor nodes are highly constrained in terms of power consumption and computational resources (CPU, memory), and configuration (c) and large-scale distributed sensor software applications updates require without self- human intervention. Previous work on fundamental aspects of wireless sensor networks has mostly focused on communication-oriented models, in which the sensor nodes are assumed to store and process the data, coordinate their transmissions, organize the routing of messages within the network, and relay the data to a remote receiver. Although some of these models provide useful insights (e.g. into the connectivity characteristics or the overall power efficiency of sensor networks) there is a strong need for formal methods that capture the inherent processing and memory constraints, and illuminate the massively parallel nature of in-network computation. Our take is to develop process calculi for sensor networks building on formalisms for concurrent distributed systems and mobile code (most notably, pi-calculus). The envisioned tools will enable us to (a) prove the correctness and feasibility of different data gathering and communication protocols (e.g. by exploiting behavioral equivalence between processes), and (b) carry out formal comparisons of different 177 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA schemes by quantifying the minimum amount of required resources. Based on the results of the first task we will attack another fundamental problem in sensor networks: the need for sensor programming languages with self-configuration and distributed update capabilities. We propose to develop specifically tailored high level idioms for sensor networks that capitalize on notions such as mobile code and selfmaintenance. Finally, we will implement and test the developed programming tools on a sensor networking prototype. Real-life experiments will allow us to better understand sensor networking constraints and further improve our designs. We believe that our interdisciplinary team of computer scientists and electrical engineers is well equipped to contribute both in theory and in practice to the advancement of sensor network programming. Acron / Ref C-Mobile Title Advanced MBMS for the future mobile world Funding EU,IST Programme Descript. The strategic objective of C-MOBILE is to foster the evolution of the mobile broadcast business by providing enhancements to the 3GPP MBMS for systems beyond 3G. It will address both resource efficiency and service flexibility, by close coupling of broadcast and communication capabilities on all layers, covering the radio access, core network and the service enablers, across multiple technologies, providing a smooth migration for MBMS evolution, which will be in line with the vision of a federated global multicast broadcast transport as well as emerging beyond 3G standards. Within the radio access network it will propose new radio interface technologies, radio resource management and new topological approaches in the architecture for an efficient support of enhanced MBMS services allowing a commercially attractive implementation. C-MOBILE will help to understand how best to organise and schedule MBMS content from the BM-SC through the core network, 178 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA radio access, to the end users. Since this is multimedia content, interactions with the 3GPP IP Multimedia Subsystem are expected and C-MOBILE will explicitly investigate how best MBMS can make use of capabilities provided by the IMS. The current concept of group communication is narrow within Release 6 MBMS specification. CMOBILE will research, investigate and define ways to use multicast technology to support personalized services and in particular the concept of multicast content community where users also contribute to the multicast service. Key market and business requirements for multicast-broadcast services will be identified to aid defining research directions, leading also to new business models involving the various players. To that end it is critical to understand the needs of multicastbroadcast users, network operators, and content providers. The project intends to make important contributions to the standardisation bodies and to prove experimentally or via system level simulations innovative concepts. Acron / Ref C-CAST Title Context Casting Funding EU-FP7 ICT Descript. Project Context Casting (C-CAST) main objective is to evolve mobile multimedia multicasting to exploit the increasing integration of mobile devices with our everyday physical world and environment. The key motivation for this project and why we believe Europe needs a project on Context Casting is because multicasting is the key enabler that will make mobile context aware services commercially attractive. Use of mobile multicast communication especially for multimedia content has always been a very attractive proposition. There will be many situations when a multicast or broadcast will be a much more affective and appropriate form of communication service but the majority are dynamic, situation specific and consequently great service opportunities are lost. C-CAST is based on two main competence areas: creation of 179 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA context awareness and multicasting technologies. Context information defines groups that demand the same information or service. These services are delivered efficiently by multicasting bearers. The project will research, investigate and define ways to use the situation/environment of a user (a mobile device) to initiate group communication. This environment mediated multicast may be triggered by an event or something in the physical environment offering a situation or context orientated service. C-CAST will provide an end-to-end context-aware communication framework specifically for intelligent multicast-broadcast services.

Acron / Ref Title FLAD/2-05/08 Foundations of Future Wireless Communications Systems: Analysis, 182 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Design and Optimization Funding FLAD and National Science Foundation Descript. The main objective of the research project Foundations of Future Communications Systems: Analysis, Design and Optimization is to explore a novel framework based on the interplay between information theory and estimation theory in the analysis, design and optimization of communications systems with relevance in practice. The advent of the information age has also been igniting the development of a whole telecommunications infrastructure to support the ubiquitous access to the Internet at ever increasing information rates. The last decade has in fact witnessed an exponential growth in wireless communications systems and services, e.g., 2nd and 3rd generation systems as well as WiFi and WiMax, with this revolution being fuelled by constant technological breakthroughs to enhance transmission performance over the wireless medium. The discipline of information theory has been constantly at the heart of this revolution, since it establishes the fundamental limits of communications systems. Yet, the presence of complex communication system features often precludes system design in a rigorous information-theoretic way due to the lack of appropriate mathematical tools, with system designers often resorting to engineering experience and insight. We propose a different approach: the analysis, design and optimization of communications systems based on connections between the key quantities in information theory and estimation theory. The expected outcomes of this three-year embryonic research are: essential theoretic and practical methodologies to design enhanced communications systems in a rigorous information theoretic way; and novel telecommunications technical systems, solutions including to WiFi optimize and WiMax current wireless networks, as well as digital subscriber line (DSL) networks. Our research team gathers considerable expertise in a wide range of complementary topics such as information theory, estimation theory and communications systems and networks, all of which are necessary to meet both the theoretical and practical challenges of this research.

The issues to be addressed in the design of the new architecture include the following (we assume the availability of context information and mainly steer our focus on four important correlative sub-areas): (1) Context-Aware Network Resource Provisioning, (2) Intelligent Context-Based Network Selection in the heterogeneous networks environment, (3) Support of Network Coding, (4) ContextAided Seamless Mobility.

This Wireless Access Network shall be exploitable not only by the conventional Internet Service Providers (ISP), such as PT, but also by the content providers that will exploit the DVB spectrum. Since DVB is a broadcast technology, it is necessary to provide a return channel in a different technology, so both types of wireless providers need to cooperate. Acron / Ref Title Funding Descript.

The KLog project envisages to investigate and apply the tools and techniques of mathematical logic, in a broad sense, to the systematic study and design of special purpose classical and quantum kleistic (from the greek word kleisis) logics, that may provide a deeper understanding of the various aspects of information security, and ultimately contribute 185 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA to the improvement of the available toolset of formal methods. This research will contribute to a better understanding of the relevant concepts and their relationships, and help to solve and clarify some of the open problems and key concerns of the area. The subjects to be addressed include the design and study of logics for reasoning about classical security protocols in distributed settings, ranging from the ideal world of perfect cryptography to the more realistic probabilistic setting where polynomially bounded adversaries are assumed, while also exploring type-theoretical logic systems targeted at flexible information flow analysis in languages supporting code mobility and declassification that could be used to express distributed protocols; and the logical study of quantum computation and information and its applications to security, eventually leading to quantum extensions of the logics for classical security, by considering quantum computation capabilities and quantum communication channels. The project will also not neglect the development of the logical foundations of combined logics and their algebraic counterparts motivated by the more applied research. Accordingly, the project is organized in three tasks: (T0) Logic in Computing; (T1) Logic for Classical Security; and (T2) Logic for Quantum Security. Acron / Ref Title MOGGY / PTDC/EIA/70830/2006 MOGGY - A Browser-Based Massive Multiplayer Online Game Engine Architecture Funding Descript. FCT/PTDC A game engine is a structured collection of several software modules (i.e. 2D and 3D graphics, physics, collision detection, input/output, sound, artificial intelligence, network, database, and graphical user interface modules) that together enable to run video games on a computer, game console, PDA, etc. The essential difference between a traditional game engine and a MMOG (Multiplayer Online Game) engine lies in the network and database modules. Usually, MMOGs have large databases over a distributed 186 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA network of servers sometimes handling a huge number of logged-on users. Distributed, real-time MMOGs are a real challenge for current networking technologies in terms of quality of service (depending on networking resources such as bandwidth, latency, and computational power), network architectures and topologies (peer-to-peer, client/server, server-network), data and control architectures (centralized, distributed, replicated), scalability (i.e. adaptation to the resource changes as a result of the increase of players), and security (fighting back against cheaters and vandals). It is true that here is not much we can do about networking resources. However, by choosing a suited architecture for networking, data, and control, we can rid MMOGs of some resource limitations, or use compensatory techniques to relax their requirements. The main requirements for a MMOG engine are the following: scalabilty, fault tolerance and persistence, computational efficiency, and security. This project aims to research solutions to fulfill these requirements, as well as friendly game rules learning mechanisms, that at present tend to limit the development of more powerful and user friendly BBMMOGs. For that, we propose to use on-demand grid technology as the underlying infrastructure for hosting online games. Although it has been geared initially towards First Person Shooter (FPS) games (the worst case in terms of processing), several of the gaming services are applicable to MMORPG (Massively Multiplayer Online Role Palying Games) and BBMMOG games as well. FPS games require a tremendous amount of server resources, and, due to interactivity requirements, they also require that the server resources be placed close to the players. Since concentration of player populations can vary dramatically over time, intelligent on-demand allocation of computing resources is critical to optimize server utilization while maximizing game playing satisfaction. In addition, a grid-based shared infrastructure provides economies of scale and industrial scale resiliency, necessary prerequisites for a successful online gaming industry. 187 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Acron / Ref Vital Responder Title Monitoring Stress among First Responder Professionals Funding FCT Descript.

N-CRAVE will deliver a proof-of-concept for network coding as the major enabler in dynamic wireless network environments with multiple communicating peers, where robustness is a key challenge. The simple, yet disruptive idea of network coding is that nodes are allowed to not only forward but also process and mix the incoming independent information flows. The objective is to develop solutions for architecting and controlling wireless networks in performance-challenged and resource-constrained environments. N-CRAVE will advance knowledge of fundamentals of network coding for improving attainable performance limits of networked systems for capacity, throughput, latency, complexity and energy with a view towards practically encountered scenarios. Key protocol components of the access, transport and network layers that operate hand-in-hand with network coding will be developed. In doing so, novel lightweight techniques will be designed based on convex optimization, linear algebra and backpressure control principles for transporting maximal amount of data over the network. Emphasis will be placed on advanced modes of information transport such as multi-cast and group-to-group communication with multiple simultaneous sessions in highly volatile environments. Innovative content distribution and storage methods will be developed for various wireless architectures and application-driven performance metrics, such as throughput, delay and fairness. A major goal will be to make the techniques viable in dynamically changing, volatile environments by preserving low computational complexity and signalling load. Besides inherent benefits of network coding in capacity provisioning and robustness, positive ramifications in security will be used to fortify confidentiality, secrecy and resilience to data corruption and other threats. Finally the project will deliver an experimental wireless test-bed on which various network coding techniques will be implemented and validated. 189 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Acron / Ref Title Funding Descript. Net-PEEC Network Coding Protocols for Peer-to-Peer Content Distribution DoCoMo The most striking difference between network coded peer to peer networks and its classical non coded counterpart, is that operations carried out by the nodes are not limited to storing and forwarding copies of requested fragments. In fact, they are allowed to combine different fragments using linear combinations, thus mixing and spreading the data among multiple packets. By means of this coding and dissemination approach, we enhance the degree of diversity in the network and thus increase the likelihood that packets received from different sources carry useful data that can be decoded for timely play out. The main goal of this project is thus to exploit the rich body of network coding theory towards developing highly efficient and robust protocols for content distribution in peer to peer networks. The expected outcomes of this research are (a) an in depth understanding of the applicability of network coding to distributed storage and dissemination with particular focus on the requirements imposed by streaming media, (b) a set of protocols that can be readily used for this task, (c) performance evaluation both analytically and by means of computer simulation.

This project addresses the emerging 3D TV broadcasting services by investigating the problems associated with transmission of different stereo video coding formats. It is comprised of two main parts that run in parallel and communicate between each other by exchanging technical information in order to optimise the performance of the broadcasting system in terms of received quality and channel useful capacity. The research on 3D video deals with characterisation and optimisation of 3D video coding algorithms by developing and testing suitable error resilience methods for broadcasting such type of content. On the decoder side the project addresses error concealment methods to cope with transmission errors and improve the quality delivered to users. The particular issues related to coded depth information are receiving special attention in this project as this is the major component of 3D video which makes it different from classical 2D. Appropriate distortion measures for depth will be used to optimise performance. The project makes use of the most recent video coding standard for video (H.264/AVC) and its extension for multiview coding (H.264/MVC). 191 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Finally, a method to characterise the radio propagation channel will be developed for varying deployment scenarios. A refined method is required to effectively measure the signal coverage in DVB-T networks and to extract the effective parameters for the error pattern generator required for both source and channel coding optimisation of DVB-T transmissions. Additionally, the measured data to be obtained and included in a database for various geometries and at a number of frequencies will represent a quantum improvement, both in volume and accuracy of the database presently available to system designers. This will form a framework to radio system designers to propose fading mitigation techniques based on link level analysis using the proposed error pattern generator. Acron / Ref SECURE-COM Title Physical-Layer Security - From Theory to Practice Funding IT Descript. The main objective of the research project SECURE-COM: Physical-Layer Security: Theory and Practice is to explore the fundamental reliability and security limits of communications channels as well as to conceive, investigate and develop practical reliable and secure transmission schemes. The issues of privacy and security in wireless communication networks have taken on an increasingly important role as these networks continue to flourish worldwide. Traditionally, security is viewed as an independent feature with little or no relation to the remaining data communication tasks and, therefore, state-of-the-art cryptographic algorithms are insensitive to the physical nature of the wireless medium. However, there has been more recently a renewed interest on information-theoretic security – widely accepted as the strictest notion of security – which calls for the use of physical-layer techniques exploiting the inherent randomness of the communications medium to guarantee both reliable communication between two legitimate parties as well as secure communication in the presence of an eavesdropper. This two-year collaborative research project builds upon the information-theoretic 192 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA security foundations to i) study the fundamental reliability and security limits of communications channels and ii) conceive, investigate and develop novel practical reliable and secure physical-layer based transmission schemes. Our research team gathers considerable expertise in a wide range of complementary topics such as information and communications theory (in particular, code design), signal processing for MIMO systems, communications systems and network, and security, all of which are necessary to meet both the theoretical and practical challenges of this research.

Acron / Ref Title Funding PICS Robust joint source/channel coding for multimedia communications GRICES-CNRS 194 ANNUAL REPORT 2009 – NETWORKS AND MULTIMEDIA Descript. The MDC makes it possible to control easily the amount of redundancy introduced in the transmitted signal while maintaining good quality decoding whatever the state of the channel. However, in the case of non stationary noisy channel, few works have been dedicated to the tuning of the redundancy according to the noise level. The goal of this project is to design a MDC that controls automatically this redundancy between the descriptors according to the channel state. Furthermore, in case of embedded devices we also propose to introduce distributed coding to move the complexity from the coder to the decoder. The proposed framework includes a wavelet transform and an optimal bit allocation process of the binary resource across the different descriptors and the different wavelet subbands. Our model will take into account both the knowledge of the channels characteristics (heterogeneity, non stationarity, ...) and the propagation conditions encountered in a real environment.

It will separate management from resolution of identities at all layers, i.e. from the service to link, considering both privacy and “need-to-know” concerns. SWIFT’s user-centric Id approach addresses three views: 1) users have complete control over privacy and disclosed information dependent on the service accessed; 2) services can use a generic treatment of authentication, authorization, access control independent of the layer services managed by a unique identity; 3) commercial players can leverage new business solutions for operator, service provider or 3rd parties through its federation approach.

The detailed activities included: Materials development, fabrication and test of individual organic electronic devices: 1) Development of a new spin coating approach to fabricate insoluble patterned thin films of semiconducting and electroluminescent polymers, tuned to specific applications in organic electronics, namely photovoltaic cells, OLEDs and chemosensors. 2) Characterization and application of a blend of green emitting polymers to improve the performance of polymer-based light-emitting diodes; work on the role of charge trapping dopants on polymer-based LEDs with the use of a new electrontrap dopant; study of the effect of additives to PEDOT:PSS conductivity and to the performance of LEDs using it. 3) Synthesis of new materials for polymer-based photovoltaic cells and characterisation of the devices. 4) Development of organic memories, with special emphasis on resistive nonvolatile memories. 259 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES 5) Development of cross-linkable polymers for the preparation of active patterns using Scanning Near-Field Optical lithography (SNOL) in collaboration with the University Colledge London, UCL (UK) (Prof. Franco Cacialli) Towards unimolecular devices: 1) Studies on the formation and characterisation using AFM/STM of molecular monolayers (SAMs) on gold and graphite surfaces (UNIME project). The studies involved thiol molecules and perylene derivatives. The electrical properties of the SAMs were also characterised using STS. Theoretical calculations by quantum chemistry of the shape of molecules and their relevant molecular orbitals, in order to identify features on atomic force microscopy (AFM) images. Other activities: 1) Activities within the EU-funded project (POLYCOM), via Instituto Superior Tecnico, included the preparation and characterisation of spirofluorene-based dopants for PMMA-based thin films and plastic optical fibers. The synthesis of new dopants for this kind of applications was continued. 2) New issues on the magnetoresistance of low-dimensional conductors were enlightened by mesaurements in different crystallographic directions on a perylene based conductor having an Au dthiolate as counterion (work in collaboration with ITN and NHMF, Florida). 3) The synthetic effort on new molecular based systems featuring combined magnetic- and electrical-designed properties has proceeded with some pyridinedithiolene complexes being studied. Integrated Circuits and Systems Scope and Objectives: Objectives: The Integrated Circuit and Systems group addresses the development of design automation tools for “System-on-Chip” applications, the design of stateof-the-art Analog and Mixed-Signal IC prototypes, the development of E-Design/ELearning environments to support design activities and the research and development intelligent computation techniques applied to computational finance. 1) IC Design Automation: R & D on evolutionary computation techniques applied to analog IC design for circuit and system level design optimization, symbolic analysis for automatic topology generation. 2) Analog IC Design: R & D on reconfigurable analog and mixed signal systems for 4G mobile terminals, low-power ultra-high speed analogue-to-digital converter for 260 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES ultra-wideband wireless communications, DC-DC converters for aerospace industry, audio amplifiers class D and G. 3) Computational Finance: R & D on intelligent computation and pattern recognition techniques applied to stock market for portfolio composition, investment strategies definition and data acquisition. Radioastronomy Scope and Objectives: The activity of this group consists of the development of instrumentation for measurement and characterization of low-level radiation from outer space, in the microwave region. Instrumentation refers both to the electronics and physical infrastructure, including antenna mounts, drives and ancillary equipment, such as data acquisition for environmental and meteorological variables. GEM project: The Cassegrain 9-meter dish from Vertex/General Dynamics offered by Portugal Telecom was successfully installed. The IF of the 5GHz receiver, a double arm feeding a polarimeter correlator with circular polarization components was designed, tested and assembled. It is a new type of state-of-the art radioastronomy polarimeters, with a cryogenic frontend, using LNAs based on ultra-low noise InP HEMTs, characteristics designed at IT, manufactured by Chalmers University of Technology, after license from JPL/NASA. A new optics configuration for the antenna, comprising a new corrugated horn feed, modelled with GRASP (ESA certified) was produced. A new module for antenna precision control was designed and tested: 3AC - Antenna Attitude Automatic Control, with TELESAL funding. GEM will contribute also to the calibration of the MWR receiver aboard the JUNO Polar Orbiter planetary spacecraft, which will be launched in 2010 to Jupiter to monitor the jovian atmosphere through radiometric analysis in the 1-10GHz band. PrepSKA: This project effectively started in late 2008. Preparation for the implementation plan, concerning: network study and information gathering on best current technologies for the digital data back haul between telescope stations; and time and LO distribution; recollection of data on super-low noise pHEMT transistors. 261 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES These could be candidates for LNA frontends and IF part of receivers and at the same time respond to cost issues of mass production of important components for the Square Kilometer Array. Instrumentation and Measurement Scope and Objectives: The Instrumentation and Measurement Group works in the broad domain of Metrology. In 2009 the main topics addressed were: • Analogue-to-digital and digital-to-analogue conversion; • Measurement of electrical quantities; • Sensors and transducers; • Signal acquisition and automated and telemetric measuring systems; • Signal processing applied to sensors and instrumentation. 1) The effect of phase noise and jitter on the Histogram Test of ADCs was studied. 2) A study of the uncertainty of analogue to digital converter test methods, namely of the Histogram Test Method, the Random Noise Test Method and the Sine Fitting Test Method was conducted. Different non-ideal effects like additive noise, jitter, phase noise and harmonic distortion were taken into consideration. 3) The work on multi harmonic sine fitting algorithm for impedance measurement and power quality analysis was continued. 4) A DSP based impedance measurement prototype was developed and implemented. The system includes a DDS to generate the sine signal at the desired measurement frequency. Overall, preliminary results demonstrate the stability of the measurement system without any significant temperature or aging drifts. 5) IT internal project CLASSE, which aims at classifying defects inside conductive non-magnetic plates, continued. The mathematical basis of non destructive testing is being developed in two parts. In the first part, the physics of the induction system is simulated in the forward problem either using a numerical method like the finite element method (FEM) or an artificial intelligent technique (ANN). The simulated system is used to preview the correspondence between first order variations in the secondary magnetic field to conductive perturbations in the conductive body. The second part of this study is the formulation of the inverse relation of this correspondence in order to reconstruct the conductivity images for a 262 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES three dimensional sample object. Since the signal from a deeper voxel is smaller than surface voxel, measurement noise corrupts more the information from deeper voxels. However, the relation between the magnetic measurements and the conductivity distribution is nonlinear. Thus, one way to estimate the solution is to linearize the forward problem around an initial conductivity distribution and update the conductivity distribution using a suitable algorithm by comparing the calculated fields with the measurements. Several algorithms can be used to minimize the norm of ||S x - b|| when solving for x. These algorithms must be investigated in order to select the one that provides the best performance for the problem to be evaluated. The mathematical relation between the conductivity distribution and the measurements is the backbone of the imaging algorithm. The classification of defects in metallic plates is carried out analysing the images produced by magnetic field sensors, which detect the magnetic field produced by the eddy currents when the material is subject to a primary time-varying excitation field. To produce a correct classification those images must be clear (noise-free) and acquired in the same conditions. During 2009 a fruitful work on signal processing was carried out in order to proceed with that classification. The obtained signal is very sensitive to probe/plate distance, and therefore the attenuation law with distance was determined. All the disturbances originated by probe misalignments were identified and corrected. Another important result was the determination of the images that should be obtained when the probe was rotated. Using the previous results it was possible to characterize the dimensions of a crack in an aluminium plate. 6) A study on the uncertainty characterization of ellipse and sine fitting algorithms on impedance measurements was conducted. 7) Signal processing algorithms (ellipse fitting and sine fitting) to be applied on DSP based instruments were optimized 8) New procedures for online detection of broken bars in induction machines were developed. 9) Atmospheric optical properties using digital photography were determined. 10) The algorithm for two-channel sinewave parameter estimation based on spectral fitting was improved to include weighted least-squares, thus significantly improving the precision of the estimated parameters and reducing the number of required iterations for convergence. In addition, the theoretical Cramér-Rao lower bound of the estimator is now used to control the convergence criteria. This 263 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES innovative approach further reduces the number of iterations, increasing the speed of the algorithm. The sine-fitting algorithms implementations were improved so that they require less memory. This modification is crucial due to the fact that the initial memory requirements of the algorithms effectively limited the number of samples that could be processed. With this further improvement, the number of samples can be significantly increased and thus further reduce the precision of the estimated parameters. 11) Automatic tracking algorithms for millimetre-wave antennas were developed. 12) Advanced signal processing techniques for instrumentation and measurements applications (non-linear A/D converters, calibration and auto-calibration procedures applied to different measurement systems, advanced signal processing technique) were developed. 13) Static and dynamic characterization of sensors and measurement system (polarography, heavy metals detectors, turbidity, pH and conductivity sensors) were performed. 14) An I&M industrial transmission systems based on Foundation Fieldbus (FF), HART e CAN protocols was implemented. 14) Different architectures of water quality monitoring nodes that include the RFID UHF components as part of IEEE1451.4 standard for smart sensors implementation were designed and tested. A patent in the area of IEEE1451.4 implementation was registered. 15) In the domain of biomedical applications worth mentioning: • The design and implementation of ubiquitous architecture associated with cardiac and respiratory activity monitoring for elderly and persons with severe restriction of mobility; • The design and implementation of physiological parameters (BCG, PPG) measurement channels embedded on wheelchair. A smart wheelchair prototype characterized by fully capabilities on biomedical signal sensing is under construction; • The development of novel algorithms including the Independent Component Analysis to obtain accurate estimation of heart rate and respiration rate from the signals delivered by sensors embedded in a wheelchair. A patent in the area of ubiquitous sensing system materialized by a wheelchair was registered. 264 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES In 2009, the following services to external entities were rendered: • Collaboration with the Department of Minas of the Instituto Superior Técnico and with Universidade de Aveiro in measuring moisture in stone panels found in ancient churches. • Collaboration with Instituto Tecnológico e Nuclear (ITN) in automating the operation of their ion implanter. • Development and implementation of an instrumentation network for broadband RF spectrum monitoring for ANACOM.

Apart from some more theoretical oriented studies, my research has mainly been focused in the design, convergence analysis, implementation and testing of algorithms for the solution of many important problems in these areas. I have also been collaborating with researchers of other areas in the design and solution of some models of engineering and finance. The most relevant topics are presented below. i).

Logic and Computation 1) Research work during 2006 focused on exploring the computational capabilities of naturally inspired continuous-time dynamical systems, namely recurrent neural networks featuring complex spatiotemporal regimes. The research was situated in the framework of the emergent field of natural computing, or computing with natural paradigms. In particular, connections began being established with the area of reservoir computing, with concrete suggestions for the harnessing of complexity aiming at greater flexibility and adequacy in the online computation of dynamical functions. The development of so-called chaotic modules was proposed as a configurable way of generating complex dynamical behavior with physically realistic neural nets, in view of applications that may benefit from that source of complexity. In 2009 the computational capabilities of naturally inspired continuous systems were investigated, following previous work. In a general setting of computing via 267 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES suitable perturbations of dynamical systems, spatially extended systems were especially considered, although not exclusively. A careful examination of computational processes in the living brain assisted in proposing and consolidating new formal computing paradigms and algorithms, based on dynamical characteristics previously overlooked in the literature. 2) Computability in dynamical systems: We intend to propose computability results about some classical topics from dynamical systems theory (smale horseshoe, stable manifold theorem, etc.). Analog computation: We intend to propose lower and upper bounds on the computational capabilities of analytic dynamical systems operating under the presence of perturbations. 3) We developed various function algebra characterizations for the functions of computable analysis. While computable analysis is defined via Turing Machines, our function algebras are defined using differential equations; thus our work characterizes a discrete model with a continuous model. We improved the work of others, and were able to re-use our earlier techniques, thus evidencing the generality of our approach. We also investigated other analog machine models. I continued work on a kind of type theory for Bounded Arithmetic, a subtheory of Peano Arithmetic with close ties to computational complexity theory 268 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES 4.4.4 Runing and Concluded Projects Overview Funding Agency Number Ciência Viva 2 CRUP 1 DSIC/ Ministerio de Education y Ciencia Espanhol 1 EC - FP7 1 EU - FP7 2 FCT/POCI 3 FCT/POSC 3 FCT/PTDC 11 ICP/ANACOM 1 IEEE Instrumentation and Measurement, TC-25 Commitee 1 Instituto de Telecomunicações 7 Total 33 Table 30 – Number of active projects running in the Basic Sciences and Enabling Technologies Area in 2009 269 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES Activity in projects Acron / Ref Title POLYCOM Plastic Optical Fibers with Embedded Active Polymers for Data Communications Funding EU,IST Programme script.

The research team’s expertise in test and characterization of analog to digital converters, signal processing algorithms, power quality measurements, development of modern digital instrumentation and impedance measurements will be used in the development and implementation of an inexpensive accurate impedance analyzer to operate in the frequency range from 10 Hz up to 1 MHz. Following the team’s previous work, a instrument prototype including all the system electronics and the software will be built. The device is based on the traditional I-V method coupled with analog to digital conversion and signal processing algorithms to be executed in the prototype digital signal processor. The algorithms to be implemented will determine the parameters of the sine signals that best fit the acquired samples of two channels and thus estimate the unknown impedance parameters. The accuracy of the final instrument will depend on the project progress but basic accuracies of 0.1% for the impedance magnitude and 0.01º for the phase or better are expected. Acron / Ref MATRIX / PTDC/EEA-ENE/67350/2006 Title Electric Drives Based on Matrix Converters Funding FCT/PTDC Descript. The main objective of this project is to develop an electric drive, based on matrix converters, with self-diagnostic and fault-tolerant capabilities. The drive, which will rely on the use of induction motors 271 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES and PMSMs, will allow to detect and locate any fault in the matrix converter. After its detection, the control system of the drive will enter in a fault-tolerant operating mode, according to which the control strategy will be modified in order to minimize the consequences of the fault and thus maintaining the system running, although with degraded performance. Besides the detection of faults in the matrix converter, and in the case of the induction motor drive, the integrated diagnostic system should also be able to detect faults in the motor, namely stator and rotor faults, bearing faults and airgap eccentricity. The drive obtained with these new features combines the advantages of the matrix converter with the high reliability granted by the integrated and fault-tolerant diagnostic/control system.

Acron / Ref CRACK / PTDC/EEA-ELC/67719/2006 Title Flaw Imaging in Metals by Contactless Conductivity Funding FCT/PTDC Descript. The measuring principle is based on the phenomenon whereby the impedance of a coil generating a time-varying magnetic field changes in the presence of a conductive material as eddy currents are induced in the material. Therefore the idea of a contactless electrical conductivity imaging system (CECIS) is based on a sensor 272 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES composed of two coils. One of the coils, designated the transmitter coil, is driven by an alternating current and generates an oscillating magnetic field that induces currents inside the object to be tested. These induced currents are related to the conductivity distribution of the body. Another coil, the receiver coil, measures the total magnetic field. One component of the magnetic field is related to the primary imposed currents and the other component is related to the induced eddy currents. As the signal originated from deeper voxel significantly attenuates before it reaches the receiving coil the information gets easily corrupted by measurement noise. By incorporating into the design a real time digital signal processor able to perform advanced signal processing techniques it is possible to increase significantly the range of the sensor. Two solutions are envisaged to accumulate data either by relocating the probe several times using a XY scanning mechanism or by using an array of sensors, i. e., several probes in the vicinity of the object to be tested. The mathematical basis of this methodology is developed in two parts. In the first part, the physics of the induction system is simulated in the forward problem either using a numerical method like the finite element method (FEM) or an artificial intelligent technique (ANN). The simulated system is used to preview the correspondence between first order variations in the secondary magnetic field to conductive perturbations in the conductive body. A set of equations in the discrete form can be formulated: Sx=b, where x is the unknown conductivity perturbation vector, b is the magnetic field measurement vector and S is the sensitivity matrix. The second part of this study is the formulation of the inverse relation of this correspondence in order to reconstruct the conductivity images for a three dimensional sample object: b=S x + y, where y represents unknown measurement noise present in the real scenario. Since the signal from a deeper voxel is smaller than surface voxel, measurement noise corrupts more the information from deeper voxels. However, the relation between the magnetic 273 ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES measurements and the conductivity distribution is nonlinear. Thus, one way to estimate the solution is to linearize the forward problem around an initial conductivity distribution and update the conductivity distribution using a suitable algorithm by comparing the calculated fields with the measurements. Several algorithms can be used to minimize the norm of ||S x - b|| when solving for x. These algorithms must be investigated in order to select the one that provides the best performance for the problem to be evaluated. The mathematical relation between the conductivity distribution and the measurements is the backbone of the imaging algorithm.

The baseline design for the SKA is an interferometer array capable of imaging the radio sky at frequencies from ~70 MHz to ~25 GHz, and providing an all-sky monitoring capability at frequencies below 1 GHz. The telescope is to be built in three phases, and will be able to carry out significant scientific observations as it is being built. The concept involves parabolic dishes with innovative feeds to maximize a combination of spatial and frequency coverage; at lower frequencies phased arrays can become cost-effective and offer new operational capabilities. Technological innovation, closely paralleling commercial IT developments, is the key to the design concepts under investigation and to the target cost of 1.5 billion Euro. Data transport rates are likely to be in the range of 100 Gigabits/sec to Tera-bits/sec, with Petaflop capacity required for the central processor. Much of the required technology is currently being developed in the course of specific design studies (including the EC funded FP6 SKA Design Study, SKADS) and the construction of several SKA Pathfinder instruments around the world. The final step of integrating the accumulated R&D knowledge into a detailed system design for the SKA, is planned to take place from 2008 to 2011, with the first three years being under the aegis of PrepSKA.

Non destructive testing (NDT) is of paramount importance for ensuring the integrity of materials. Eddy currents testing (ECT) is one of several methods like, remote field testing (RFT), flux leakage and Barkhausen noise, that use electromagnetic theory to examine conducting materials. It is a particularly attractive test because it offers both very high detectability and high scanning speeds. Besides direct contact with the test material is not necessary. Nowadays, with the use of microprocessor based measuring instruments, the potential and user-friendliness of eddy currents testing has been greatly enhanced. The role of the computer has two different components: one related with the possibility to automate the measuring system (data acquisition control, data processing, signal classification and displaying) and other with numerical modeling of the testing process. The computing capabilities are used to quantitatively predict eddy current signals for realistic situations and to evaluate crack profiles from testing signals by solving the inverse problem of the physical phenomenon under test. At this time the tasks related to the data acquisition, signal processing and graphical representation, are already under way, with some work already published [1-6,8,9]. The point is that the inverse problem of computing the crack profiles from the eddy currents data is ill-posed, i.e., the crack profiles are not univocally determined by the measured eddy currents. A possible approach to mitigate the ill-posedness nature of this inverse problem is to classify the crack profiles according to the different types of material defects. The idea is to exploit the a priori knowledge of the problem and thus select the proper defect model. In order to investigate the assumptions of the technique, particularly, patterns identification, a huge amount of data is essential 280 and ANNUAL REPORT 2009 – BASIC SCIENCES & ENABLING TECHNOLOGIES experimentation is necessary.
