Abstract

The talk, after a short introduction into the activities of the Networks Research Lab (NetRL), will introduce a number of European Commission and locally funded research projects NetRL is involved. Then it will focus on two areas of research.

In VANETS, the first research area, we look at the design of an effective broadcast scheme which can facilitate fast and reliable dissemination of messages in the vicinity of an expected event, such as a car accident, and also present the concept of Information Hovering, where useful messages need to remain available within a specific area.

In Next Generation Mobile Networks (NGNs), the second research area, we look into whether cooperation can be motivated in interactive situations related to Network Selection in NGNs, where heterogeneous access technologies may co-exist. We consider three different interactive situations and use Game theory to assess the conditions and strategies leading to cooperation between user(s) and Network Providers, and investigate profitable behaviours of the participating entities.

Finally, the talk will briefly introduce a new handover technique for 3GPP MBMS (Multimedia Broadcast Multicast Service) where Point-to-Point (P-t-P) and Point-to-Multipoint (P-t-M) transmission mode services can co-exist within a cell.

Speaker's biography

Andreas Pitsillides is a Professor in the Department of Computer Science, University of Cyprus, and heads the Networks Research Laboratory (NetRL). Andreas is also a Founding member and Chairman of the Board of the Cyprus Academic and Research Network (CYNET) since its establishment in 2000. During 2008 he was on sabbatical visiting the University of Cape Town and the University of Pretoria in South Africa, the University of Southern California, and Goldsmiths, University of London. His research interests include fixed and wireless Networks (ad-hoc and sensor networks, VANETS, WLANs&WMANs, UMTS Third Generation mobile networks and beyond, 4G), flow and congestion control, resource allocation and radio resource management, and Internet technologies and their application in Mobile e-Services, e.g. in Tele-Healthcare, and security issues. He has a particular interest in adapting tools from various fields of applied mathematics such as adaptive non-linear control theory, computational intelligence, and recently nature inspired techniques, to solve problems in communication networks. Andreas has published over 200 research papers and book chapters, and is the co-editor with Petros Ioannou of the book on Modelling and Control of Complex Systems (CRC, 2007).
