Abstract

To assure public safety, Intelligent Transportation systems provide different modes of traffic management. Vehicular ad-hoc network not only provides public safety, but also provide other communication between the vehicles. Generally VANET relies on broadcasting emergency messages. Simply broadcasting the messages will lead to congestion and collision in the network which is termed as broadcasting storm problem. Many researches have gone into the process of reducing the broadcast storm problem. While concentrating on alleviating the broadcast storm problem in VANET, time management is also to be considered. Emergency messages must be reachable within the accidental zone in a short period of time. This paper, proposes a Spanning Tree based broadcasting for VANET which effectively reduces the end-to-end delay, latency and considerably improves the packet delivery ratio. The proposed algorithm is implemented in the NS-2 simulator and compared with the best known TLO (The last one) approach and found to perform better. Since the number of rebroadcasts in this spanning tree based algorithm is considerably reduced, the number of collisions also decreases, thereby resulting in an efficient utilization of the network bandwidth.
