Abstract
Reliable data dissemination becomes a critical issue in Vehicular Ad Hoc Network (VANET) due to its high dynamic nature. Moreover, data delivery ratio degrades after a road junction as the vehicles depart in different directions. Existing schemes such as static node assisted adaptive data dissemination (SADV) has attempted to increase the delivery ratio for medium and low vehicular density. However in a real time scenario, the vehicular density at the road junction is higher than that of the roads. Our proposed system manages to improve the data dissemination at the junction even if the vehicular density is high. This paper introduces a routing protocol called Vehicular Cluster Assisted Routing (VCAR) for scalable networks. The objective of the proposal is to upgrade the performance of VANET under high traffic scenario. To support data dissemination at the junction, the associated network is effectively partitioned into groups called clusters and they tend to move along with the vehicles towards the destination. It is observed that the moving cluster significantly improves the connection time and thereby delivery ratio too. Scalability is also considered while designing the routing.
