A dynamically adjustable hybrid location- and motion -based routing protocol is presented. Central to this protocol is the decision-making mechanism that will determine whether a message will be forwarded to a neighbour node or not, at a neighbourhood check point. The decision mechanism is driven by an assessment of the “rate of advancing the message towards the destination” that is based on the node location and a prediction of the time that the node would (or should) keep the message (referred to as the message retaining time) if it were the message carrying one. This retaining time is derived by each node involved in a neighbourhood check and is based on environmental conditions (mobility and density factors), as well as specific own nodal parameters (location and motion). In the second part, the retaining time is exploited to decide how often should neighbourhood information be acquired and utilized by a routing protocol.
Prof. Ioannis Stavrakakis (IEEE Fellow, Dept Chair 2013 – ), is Professor in the Dept of Informatics and Telecommunications of the National and Kapodistrian University of Athens. He received his Diploma in Electrical Engineering from the Aristotelian University of Thessaloniki and his PhD in the same field from University of Virginia, USA. He served as Assistant Professor in CSEE, University of Vermont (USA), 1988-1994; Associate Professor of Electrical and Computer Engineering, Northeastern University, Boston (USA), 1994-1999; Associate Professor of Informatics and Telecommunications, National and Kapodistrian University of Athens (Greece), 1999-2002; and as Professor since 2002. Teaching and research interests are focused on resource allocation protocols and stochastic traffic management and congestion control for communication networks (peer-to-peer, mobile, ad hoc, autonomic, delay tolerant, social and future Internet), with recent emphasis on human driven decision-making in distributed competitive environments and information-centric networking. His research has been published in over 220 scientific journals and conference proceedings and was funded by USA-NSF, DARPA, GTE, BBN and Motorola (USA) as well as Greek and European Union (IST, FET, FIRE) funding agencies. He has received 2 Marie-Curie grants for training post and has supervised about 20 Ph.D. graduates. He has served repeatedly in NSF and EU-IST research proposal review panels and involved in the TPC and organization of numerous conferences sponsored by IEEE, ACM, ITC and IFIP societies. He has served as chairman of IFIP WG6.3 and elected officer for IEEE Technical Committee on Computer Communications (TCCC). He has been in the editorial board of Proceedings of IEEE (2015-), Computer Communications (2008-), IEEE/ACM transactions on Networking, ACM /Springer Wireless Networks and Computer Networks journals. He has served as head of the Communications and Signal Processing Division, Director of Graduate Studies and Dept Chair.
