On demand set up, fault tolerance and unconstrained connectivity are the major advantages of mobile computing, that's why it continues to enjoy rapid growth. In last three decades, tremendous improvement is made in the area of wireless ad-hoc network. Now a days, one of the most attractive research topic is inter vehicle communication, i.e., realization of mobile ad-hoc network. VANETs have been attracting an increasing attention from both industry as well as research communities. It requires reliable packet transmission, but rapid topology changing and frequent disconnection makes it difficult to design an efficient routing protocol.
