Enhance Trust Based Routing Techniques Against Sinkhole Attack in AODV Based VANET
Ad hoc network is a collection of wireless nodes communicating among themselves over multihop paths, without the help of any infrastructure such as base stations or access points. Vehicular Ad-hoc NETworks (VANETs) are self-organizing, self-configuring confederation of wireless systems. At present, vehicular networks are still not considered to be very efficient because of their rapid topology changes and their highly dynamic structure. The Vehicular Ad-hoc Networks security attack is a challenging job. A new routing protocol based on the trust model is proposed and analyzed in this paper. Here each node calculates trust value and association status for all its neighboring nodes through monitoring its behavior in the network.
