Towards a Trusted Vehicular Routing in VANET

摘要: Vehicular ad-hoc network (VANET) offers a large number of new potential applications. Drivers may benefit from collision warning, road sign alarms and in-place traffic view, others. This tends to operate without any infra-structure or legacy client server communication. However, due some special properties such as high mobility, partitioning, constrained topology, situations in which the topology changes dynamically are tempting attackers for various reasons, e.g. faked location malicious information. In this paper, by using trusted computing technology we propose security mechanism called TGPSR provide holistic protection geographic information routing protocol (GPSR) has great applied VANET. is expected effectively prevent behaviors especially tampering with neighbor table (NLT). Extensive simulations confirm that superior GPSR defending against compromising performance through comparing many metrics throughput, packet loss rate, delivery jitter, average delay, efficiency, simulation time.
