A Reliable multicast routing approach for VANET

Safety applications of inter-vehicle and vehicle-to-roadside communication that make use of vehicular ad hoc networks (VANETs) will often require reliable communication that provides guaranteed real-time message propagation. An important aspect of network dynamics is failure handling, as link/node failure due to high mobility of nodes introduces service disruption in wireless network. Since service disruption depends on the reliability of the path, therefore it is important to take reliability into account during multicast member join. In this paper, we have proposed a Fuzzy ARTMAP based QoS based reliable method (QBRM) to address this problem of routing in a dynamic QoS aware Multicast environment. Our simulated results shows that the performance of this QoS-based Reliable Multicast Routing is superior in terms of cost and number of query messages in cases where the average multicast group size was large and the bias of the joining rate was close to one but performed poorly for small groups with respect to greedy algorithms.
