SURVEY: PERFORMANCE ENHANCEMENT OF ROUTING PROTOCOL USING DIVERSE MOBILITY MODELS IN VANET

Vehicular Ad-hoc network (VANET) is a collection of mobile nodes that are randomly located so that the connections between nodes are dynamically changing.  Without the use of the existing network infrastructure, VANET mobile nodes form a temporary network. At present VANET is becoming an interesting research area characteristic that led to the need for competent routing and resource saving protocols and also to fit with different mobility environments. The aim of this paper is to give a survey of the VANETs routing Scenario. It also gives an overview of Vehicular ad hoc networks, existing VANET routing protocols and the exiting two mobility Models. The paper also describes the outlines of VANETs, investigates different routing schemes that have been developed for VANETs, and providing classifications of VANET routing protocols with  different classification forms and gives summarization.
