Evaluating the impact of a novel warning message dissemination scheme for VANETs using real city maps

Abstract

In traffic safety applications for Vehicular ad hoc networks(VANETs), warning messages have to be disseminated in order to increase the number of vehicles receiving the traffic warning information. Hence, redundancy, contention, and packet collisions due to simultaneous forwarding (usually known as the broadcast storm problem) are prone to occur. In the past, several approaches have been proposed to solve the broadcast storm problem in multi-hop wireless networks such as Mobile ad hoc Networks (MANETs). Among them we can find counter-based, distance-based, location-based, cluster-based, and probabilistic schemes. In this paper, we present the enhanced Street Broadcast Reduction(eSBR), a novel scheme for VANETs designed to mitigate the broadcast storm problem in real urban scenarios. We evaluate the impact that our scheme has on performance when applied to VANET scenarios based on real city maps. © 2010 Springer-Verlag.
