A Model Based Connectivity and Localization Strategy for Vehicular Ad Hoc Networks

Nowadays, researchers have performed extensive experiments to study the feasibility and Connectivity of vehicle access. We investigate connectivity in the ad hoc network formed between vehicles that move on a typical highway. We use the common model in vehicular traffic theory. Since a vehicle spends a large portion of the connection time in this poor link quality area, "No GPS Zone" the data throughput can be significantly reduced. Relative location information is an important aspect in vehicular Ad hoc networks. It helps to build vehicle topology maps, also provides location tracking of nearby vehicles. In this paper, we propose a protocol of localization using VANET where no GPS information is available based on clustering and link prediction and also has the advantage to use a single coordinates system. Using the network simulator NS-2 and also checked the mobility scenario in SUMO by implementing the above protocol.
