An Optimized Cluster Based Routing Technique in VANET for Next Generation Network

Since last few years, research in the field of vehicular networking has gained much attention and popularity among the industries and academia. Intelligent approach for such technology is the challenge. In this paper, we have taken an attempt to optimize the routing algorithm for vehicular adhoc networking (VANET). Ant Colony Optimization (ACO) is an optimization technique and is applied based on clustering technique. To improve the safety factor and efficiency and to develop an intelligent transport system, it is highly conceptual with the wireless technology. It is a special type of MANET, because of the variation of routing protocols. Even if the protocols of MANET are feasible, they are not able to provide the optimum throughput required for a fast changing vehicular ad hoc network. Positions of the vehicles create the zone and the optimization is zone based. Ant Colony algorithm is combined with zone based clustering algorithm to improve the result. This approach combines the advantages of both the techniques, the ant colony algorithm as well as the zone based routing algorithm. Routing overhead has been compared between AODV, MARDYMO and TACR protocols and depicted in the graphical plots.
