摘要：A Vehicular Ad Hoc Network (VANET) is an instance of MANETs that establishes wireless connections between cars. VANET provides three major classes of applications possible in VANET are safety oriented, convenience oriented and commercial oriented. One key component of VANET simulations is the movement pattern of vehicles, also called the mobility model. Mobility models determine the location of nodes in the topology at any given instant, which strongly affects network connectivity and throughput. The Mobility Model governs the set of rules that define movement pattern of nodes in ad-hoc network. Network simulators can then, by using this information, create random topologies based on nodes position and perform some tasks between the nodes. VANET requires modification of the existing MANET protocols to adapt itself into VANET scenario .Several mobility models are developed in this regard. In this Paper Various mobility Models and Routing protocols are discussed and models are compared according to different routing protocols. Simulations results are shown for different mobility models over different protocols using VanetMobiSim and NS-2.
