GPS Based Secure Communication Strategy For Vehicular Ad Hoc Networks

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 call VANET i.e. Vehicular ad-hoc network; a vehicle can communicate with its neighboring vehicles even in the absence of a central Base Station. The concept of this shortest communication is to send vehicle safety messages one-to-one or one too-many vehicles via wireless connection. Such messages are generally short in length and have very short lifetime in which they have to reach at the target. The Inter-vehicle communication system is an adhoc network with high mobility and changing number of nodes, where mobile nodes animatedly create temporary networks and transferring messages from one node to others by using multiple hops due to restriction of tiny range. The routing in vehicular Ad hoc Networks (VANET) has attracted many attentions during the last few years. So in this thesis we are focusing on the routing concept for the VANET i.e. Principles for routing, disintegration of the routing function and obligation. The data delivery through Vehicular Ad-hoc Networks is challenging since it must efficiently handle rapid topology changes and a fragmented network.
