AODV Extension using Ant Colony Optimization for Scalable Routing in VANETs

On demand set up, fault tolerance and unconstrained connectivity are the major advantages of mobile computing, that’swhy it continues to enjoy rapid growth. In last three decades, tremendous improvement is made in the area of wireless adhoc network. Now a days ,one of the most attractive research topic is inter vehicle communication i.e. realization of mobile adhoc 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. To disseminate the warning messages among vehicles to avoid accidents are sometimes a mission critical problem at some level. Therefore, this paper proposes a scheme that avoids the delay of communication that occurs due to frequent disconnection in routing. For this, the meta heuristic search i.e. ant colony optimization is combined with AODV and route repair strategy is applied to ACO.
