VANETs Mobility Model entities and its impact

Mobility Models plays a vital role in the performance evaluation of routing protocols. Research trends are now towards the development of realistic mobility models for vehicle ad hoc networks. In this paper we have given the entities and their characteristics, most important components, for the development of realistic mobility models for vehicle ad hoc networks. We have also described how these components will affect each other and network performance. In addition, we evaluated various routing protocols including DSR, AODV and OLSR using Fast Car Model (FCM), Slow Car Model (SCM) and Freeway mobility model and concluded that high mobility alone causes little affect on performance.
