AbstractPassive optical networks are nowadays the first/last mile vehicle for ultra high bandwidth to the user. The terminals on the networks are more and more sophisticated and global coverage of high data rate is lagging since it will require high volume of investment. Therefore the home network terminals are evolving at high rate requiring more functionalities, bandwidth and flexibility. Photonic integration may be the path towards reaching these objectives. This talk will observe the potential of Photonic integration as optics terminals and some of its potential applications.

AbstractIn this talk the mobile reception of Terrestrial Digital Video Broadcasting (DVB-T) signals will be discussed. The case concerns primarily users in urban environment while riding on a vehicle. To overcome the major problem of multipath fading which causes considerable variations of the signal intensity at the changing reception point and thus unstable visualization a diversity receiving scheme is used. Multiple antennas are needed for the purpose the outputs of which are further processed by DSPs. Lots of factors need to be considered when designing the stabilizing process such as the channel coding and the utilized modulation. Additionally, during industrial adoption of the proposed techniques a series of issues arise including network planning and handover procedures. Solutions to all of them are going to be debated as well.

AbstractThe convergence of fixed transport networks based on high-speed optical infrastructure and a broadband spectrally efficient wireless component has been identified as a key enabler of future access networks. The capacity and latency requirements put stringent requirements on the fronthaul design, and in the future it will likely that designing equipment for the fronthaul will be one of the main markets of optical communications. Overall to provide the features envisioned for a global and pervasive information society the two technologies optical and wireless that in the past have progressed in isolation need to merge to exploit the synergies and therefore provide cost-effective solutions. This talk presents different approaches to implement hybrid fibre-radio infrastructures suited for cloud radio access networks that will provide a framework for advanced cooperation, interference control/alignment, network virtualization, and cognitive schemes. Flexible and mobile fronthaul transceivers for the emerging C-RAN architectures that can cope with the challenges of using the existing or the future fibre to the home passive optical networks (FTTH PON) such as NGPON2 will also be presented.

AbstractResilient Communication Services Protecting End-user Applications from Disaster-based Failures Abstract: Machine Learning (ML) is a subfield of artificial intelligence that is concerned with the design, analysis, implementation, and applications of programs that learn from examples or experience. Learning from data is commercially and scientifically important. ML consists of methods and respective software that extract automatically interesting knowledge (patterns, models, relationships) in large databases of sometimes chaotic and redundant information. ML is a data-based knowledge-discovering process that has the potential not only to analyze events in retrospect but also to predict future events or important alterations. The objective of this lecture is to introduce the PhD students to the research area of ML. The lecture will give a flavor of supervised (classification and regression) versus unsupervised (clustering) learning paradigms. Distance (similarity) measures, instance based classifiers, Bayesian statistical learning, and performance evaluation (confusion matrix). ML applications, such as text mining, image classification, brain data processing will be discussed.

TitleResilient Communication Services Protecting End-user Applications from Disaster-based Failures

Speaker: Amaro de Sousa, UA/IT
Biography: Amaro de Sousa is an Assistant Professor at the Department of Electronics, Telecommunications and Informatics (DETI) of University of Aveiro. He is also a senior researcher at  the Institute of Telecommunications (IT), in Aveiro, as a member of the Applied Mathematics research group. He is a Portuguese member of the Management Committee of the European COST Action RECODIS deeply involved in the research activities concerning resilient mechanisms to protect networks against large-scale natural disasters. His research interests include network design and traffic engineering of telecommunication networks, including optical networks and multi-layer networks, with a special focus on operations research and computer science.

Abstract: Disaster-based failures can seriously disrupt a communication network, making its services unavailable. Such disruptions may follow from natural disasters, technology-related failures, or malicious attacks, and they are observably increasing in number, intensity and scale. The problem needs to be urgently addressed due to the lack of suitable mechanisms deployed in current networks. When network services that are part of a critical infrastructure become unavailable, commercial and/or societal problems are the inevitable result. The COST Action RECODIS (http:// http://cost-recodis.eu) aims to develop appropriate solutions to provide resilient communications in the presence of disaster-based disruptions of all types for existing and future communication network architectures. In this seminar, the objectives of RECODIS will be highlighted and some recent research results will be described, as an illustration of the research challenges that are been dealt with within RECODIS.

Seminar 11

TitleThe Role of Vehicular Networks in Intelligent Transportation Systems

Speaker: Susana Sargento, UA/IT
BiographySusana Sargento is an Associate Professor at the University of Aveiro and a Senior Researcher at the Institute of Telecommunications, Portugal, where she is leading the Network Architectures and Protocols (NAP) group. In March 2012, Susana has co-founded a vehicular networking company, Veniam, which builds a seamless low-cost vehicle-based internet infrastructure. She has more than 15 years of experience in technical leadership in many national and international projects, and worked closely with telecom operators and OEMs. She has been involved in several FP7 projects (4WARD, Euro-NF, C-Cast, WIP, Daidalos, C-Mobile), EU Coordinated Support Action 2012-316296 “FUTURE-CITIES”, national projects, and CMU|Portugal projects (DRIVE-IN with Carnegie Melon University). She has organized and has served as TPC-Chair in several international conferences and workshops, such as ACM MobiCom 2009 Workshop CHANTS, IEEE Globecom and IEEE ICC. She has also been a reviewer of numerous international conferences and journals, such as IEEE Wireless Communications, IEEE Networks, IEEE Communications. Her main research interests are in the areas of self-organized networks, ad-hoc and vehicular mechanisms and protocols, such as routing, mobility, security and delay-tolerant mechanisms, resource management and virtualization in both network and cloud resources, and content distribution networks. Susana is the winner of the 2016 EU Prize for Women Innovators.

AbstractThere has been a strong focus in the last 10 years on the development of vehicular network technology and mechanisms to build a reliable wireless mesh network to forward data packets in a multi-hop fashion between the vehicles and the Internet via road side units or access points. Although the vehicular technology, IEEE 802.11p, has been standardized some years ago, the number of real experiments and deployments are limited to the lab environment and small-scale trials. Moreover, the vehicular network mechanisms have been mostly tested in simulation environments, which are far from the reality of the network characteristics in real scenarios. Seeking to develop and test vehicular network mechanisms in real environments, and to explore the extent to which a vehicular mesh network can serve as a reliable and secure wireless infrastructure for mobile Internet access and the Internet of Things at street level, we built a city-scale testbed comprised of 404 connected public transit buses, 25 municipal service vehicles (garbage trucks) and 47 roadside units. This experimental platform is currently providing free WiFi to passengers in the city of Porto, Portugal. Moreover, these vehicles gather large amounts of data not just from their own sensors and the devices of the bus passengers, but also from other wireless devices that are spread around the city. This talk describes latest advances in vehicular network mechanisms and how real and large-scale vehicular network infrastructure is able to provide meaningful performance results, test new network mechanisms and develop new applications for both citizens, transportation and the city, in an Intelligent Transportation System perspective.

Seminar 12

TitleFrom performance to convergence: the challenges and directions of 5G telecommunication architectures research

Speaker: Daniel Corujo, UA/IT
BiographyDaniel Corujo concluded his PhD on Communication Middleware for the Future Mobile Internet, in 2013, where he is currently a researcher at the Instituto de Telecomunicações, coordinating the Telecommunications and Networking Group in Aveiro. He has been an active researcher and contributor to standardization in the fields of mobility management, through the IETF/IRTF, and Media Independent Handovers, through the IEEE. He has pursued such concepts under the scope of a broad range of EU FP7 research projects, such as DAIDALOS, OneLab2, 4WARD, MEDIEVAL and OFELIA, where he also played key roles from proposal elaboration to task and workpackage co-leading. Parallel to his 10 years experience on mobility management research, he has been more recently developing work on the areas of the Internet of Things, Information Centric Networking, Network Function Virtualization and Software Defined Networking, deploying new visions and enhancements of such concepts over wireless networks, in national and international research projects. He currently co-adivses several MsC and PhD students, with both industry and the academia.

AbstractThe integration of Information and Communication Technologies (ICTs) has enabled different societal areas to both benefit from added capabilities, as well as to permeate new requirements over the underlying technological fabric. Such requirements are prompting for the provision of new technological advances that go beyond the usual performance increase (in aspects such as energy efficiency, throughput and cost) and increase the demand for more flexible, dynamic and scalable operation of ICTs. This concept has been the research cornerstone for the upcoming 5G architecture, where communication performance and capability increments are being progressed in parallel with other mechanisms, such as virtualization, cloud computing and big data. This seminar addresses this latter part, where telecommunications architectures are increasingly being coupled with softwarization and virtualization mechanisms in order to cope with stringent new demands from verticals that go beyond the usual mobile or fixed customer, and actually consider millions of simultaneously connected devices, smart cities, new Internet paradigms and even concepts that go beyond the 5G landscape.
