A Survey on Routing Mechanism and Techniques in Vehicle to Vehicle Communication (VANET)

Abstract

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