In last three decade, enormous improvement is done in research area of wireless ad hoc network and now-a-days, one of the most attractive research topic is inter vehicle communication i.e. realization of mobile ad hoc network. VANET (Vehicular Ad-hoc NETwork) is a classification of MANET in which vehicles act as mobile nodes and provide a different approach to Intelligent Transport System (ITS). VANET is an emerging area for Intelligent Transportation System (ITS) which can result in increased traffic safety, collision warning through exchange of messages through wireless media. Efficient routing protocols are required for efficient communication among vehicles.
