Title: Peer-to-Peer Data Structures for Cooperative Traffic Information Systems

Abstract: Cooperative traffic information systems support the driver of a car in selectinga route, based on traffic information collected by other cars. We propose to usea peer-to-peer network based on Internet access via cellular networks to distribute traffic informationbetween the participants of such a system. This approach avoids the well-knownlimitations of VANET-based communication. Since the data maintained in acooperative traffic information system has a very specific structure, it isparticularly profitable---in terms of bandwidth consumption and latency---totailor the system to this specific application domain instead of re-usinggeneric peer-to-peer approaches. This realization led us to the development ofGraphTIS---a peer-to-peer network specifically designed to manage trafficinformation. In this paper we derive, step-by-step, the core mechanisms ofGraphTIS, starting with a standard peer-to-peer system, outlining a firstsolution---named PeerTIS---which is based on a modification of this standardDHT, and then presenting GraphTIS, a novel peer-to-peer system that has beenspecifically designed to support traffic information systems.
