CS Other Presentations

Department of Computer Science - University of Cyprus

Besides Colloquiums, the Department of Computer Science at the University of Cyprus also holds Other Presentations (Research Seminars, PhD Defenses, Short Term Courses, Demonstrations, etc.). These presentations are given by scientists who aim to present preliminary results of their research work and/or other technical material. Other Presentations serve as a forum for educating Computer Science students and related announcements are disseminated to the Department of Computer Science (i.e., the csall list):

Abstract:
Vehicle Adhoc Networks (VANETs) harness the potential of information and communication technologies to create a safer, smarter and more efficient transportation network. VANETs can increase the driver’s range of awareness beyond line-of-sight giving them the opportunity to react prior any possible danger. Additional to the safety related applications, VANETs can offer many other services such as traffic monitoring, platooning, text messaging, distributed passenger teleconferencing, file sharing, roadside e-advertisments etc. This talk discusses challenges in the design of information dissemination schemes for VANETs and proposes new solutions which are shown to work effectively. A novel traffic adaptive information hovering protocol is presented which can be used to maintain critical information in a confined area in a specific amount of time. The protocol achieves high reachability without overloading the network resources through a large number of exchanged messages. To demonstrate its applicability beyond VANETS, the derived solution is integrated in a Data Broadcasting system with a Push Server, as a means of data off-loading which significantly improves performance. Finally issues pertinent to optimal information routing are discussed. The probability of information propagation on intersections is calculated analytically and validated using simulations. The result is then used to calculate information paths with maximum probability of information delivery.

Short Bio:
Andreas Xeros received his Bachelor degree from the Computer Engineering and Informatics Department from the University of Patras in 2002. In 2004 he received his Master’s Degree in computer science with specialization in Multimedia and Creative technologies from the University of Southern California. Since 2006 he is Ph.D student at the University of Cyprus. His research interests include Information Dissemination in Vehicular Ad Hoc Networks (VANETs), Vehicular Traffic modeling and Graph Theory.
