Now a day, one of the most attractive research topics in the area of Intelligent Traffic Control is Intervehiclecommunication. In V2V communication or we can also called VANET i.e. vehicular ad-hocnetwork; a vehicle can communicate to its neighboring vehicles even in the absence of a central BaseStation. The concept of this direct communication is to send vehicle safety messages one-to-one or oneto-many vehicles via wireless connection. Such messages are usually short in length and have very shortlifetime in which they must reach at the destination. The Inter-vehicle communication system is an adhocnetwork with high mobility and changing number of nodes, where mobile nodes dynamically createtemporary networks and transferring messages from one node to others by using multiple hops due tolimitation of short range. The routing in vehicular Ad hoc Networks (VANET) has attracted manyattentions during the last few years. So in this paper we are focusing on the routing concept for theVANET i.e. principles for routing, decomposition of the routing function and requirement. The datadelivery through Vehicular Ad-hoc Networks is challenging since it must efficiently handle rapidtopology changes and a fragmented network.
