Abstract: Mobility model of a Vehicular Ad Hoc Network (VANET) is one of the key determinants for developing routing protocol for vehicular communication. The mobility pattern in the mobility model is used to simulate the movement characteristics of the vehicles, which plays an eminent role for developing an efficient routing protocol for vehicular network. The main role of the mobility model in a VANET is to influence the route discovery mechanism, reconstruction of failure links and caching procedures. This paper describes Highway, Manhattan and Freeway mobility models that represent the mobile vehicles and their movement is completely dependent on other vehicles. This paper also presents the simulation results that illustrate the importance of various routing protocols, cluster schemes and the standard 802.11p. The simulation output demonstrates how the performance of VANET routing protocol changes significantly, when the mobility model is changed.
