UC3M Report Research The group, RYSC, Communication Networks and Services of the UC3M, consists of researchers from the Department of Telematics Engineering. It is divided into three subgroups: The NETCOM group, coordinated by Professor Arturo Azcorra; The ADSCOM group, coordinated by Professor David Larrabeiti; and the FIND group, coordinated by Professor María Calderón. Our area of activity usually centres on cooperative projects and on technology transfer activities. This video will show our main lines. NETCOM has a team of 30 researchers and this critical mass permits us to undertake highly international impact researches. We regularly publish articles in prestigious scientific journals like Infocom, Conext, Transactions on Networking and Transactions on Wide Computing. Every year we receive applications from students from all over the world, who wish to study their Doctorates with us and they undergo intensive competition for a place on our team. In addition to our cutting-edge researches, we are in close contact with industries and Public Administrations. We have worked together with companies in more than 30 European projects, managing and handling 6 of them. We have our own patents and we have jointly-owned patents. We develop prototypes of innovating products for large international companies within our sector. We will now expand on the technology areas in which the NETCOM group specializes. Currently we are experiencing exponential growth in the wireless network traffic, which entails an increase in energy consumption. To meet the demands of this growth we are working on the design and prototype of new algorithms and protocols that may improve network performance and at the same time reduce energy consumption. We also work on Internet protocols and architecture. For example, we work on aspects of Inter-Domain Routing, an application of gaming theory to networks, etc. Our activity is mainly linked with European and National Projects, although we also strongly impact standardization activities, especially those of the IETF, to which we have contributed enormously, and those of other standards. The group is highly experienced in the field of Vehicular Communication. Until now we had focused on two aspects: Firstly, that vehicles may communicate with one another and with entities placed along-side roads, to improve safety in driving, and even efficiency in managing the traffic. Secondly, provide advanced Internet connection services for vehicles and their passengers, and to provide navigation programmes, or entertainment programmes like that of the real-time video. The group is also working on the Internet of the future. Specifically, on what is referred to as Information-Centric Networking, or ICN, the English abbreviation. Although these kinds of networks are considered a revolution of the current state of the Internet, we are investigating how to adapt its principles to the present networks, to start enjoying its advantages from the onset. For example, we are working towards combining the ICNs with content distribution networks, in an efficient on-demand transmission of video, in transmitting TV via IP, voice via IP, etc. It is estimated that computer devices and telecommunication equipments account for between 2% and 10% of the total energy consumption in a country like Spain. For example, at data centres the equipments consume as much energy as is required to keep them cool. Energy efficiency in communication networks is one of the most important areas of research for our group. This includes the re-designing of more intelligent protocols and mechanisms for equipments to be switched off when not in use so as to dynamically adjust the resources to demand for the services. All should be executed without the user noticing even a minimum loss of connectivity or reduction in the service. Another line of research is the possibility of legally blocking the communications. We are studying how this could be done efficiently and especially, in a certain manner. The general idea is to use cryptographic mechanisms to, on the one hand, prevent falsification of digital evidence and guarantee that all wire tapping are authorised by a judge.
