Vehicular Ad hoc NETwork (VANET) is a sub class of mobile ad hoc networks. It provides wireless communication among vehicles and vehicle to road side equipments. The communication between vehicles is used for safety, comfort and for entertainment as well. The performance of communication depends on how better the routing takes place in the network. Routing of data depends on the routing protocols being used in network. Most applications targeting VANETs rely heavily on broadcast transmission both to discover nearby vehicles, and to distribute traffic-related information to all reachable vehicles within a certain geographical area, rather than only to routing-selected hosts, like in MANETs.
