Vehicular Ad-hoc Network (VANET) technology has enticed great attention in recent days with the recent advancement in wireless local area network communication technology. VANET technology has changed the vehicles into an intelligent system carrier with their wide applications such as safety on roads, multimedia content sharing, various commerce on vehicles, etc. The rapid change in network topology and the high mobility of vehicles has lead to a frequent disconnection of network and the multihop information dissemination. Many routing techniques like flooding and minimum weighted routing with the geographical location has been followed to obtain the shortest path connectivity, but resulted in higher number of hop counts. The greedy routing technique is introduced here to obtain the routing with minimum number of hop counts, while considering the connectivity on the roads. The back bone node is introduced here to take care of the link breakage in the network and the frequent disconnection of the nodes. By considering the movement around the source and the destination, the back bone nodes enables the routing in the changed direction to keep the connectivity stable. The result of the simulation shows the use of the proposed system with its improved packet delivery ratio and the shortest end to end delay.
