Adaptive Message Passing in Vehicular Ad-hoc Networks

Abstract

A Vehicular Ad-Hoc Network, or VANET, is a form of Mobile ad-hoc network, to provide communications among nearby vehicles and between vehicles and nearby fixed equipment, usually described as roadside equipment. VANET defines protocols for intelligent way of using vehicular network. A vehicle in VANET is a mobile node which is intelligent enough to communicate with other vehicles in the network and also with the static Road Side Unit (RSU). In the current project we focus on hybrid model consisting cluster based VANET and infrastructure based VANET. In adhoc mode, only clusters are present. Each cluster will be having its own cluster head. Also cluster members of each cluster communicate with their respective cluster head. The cluster head will communicate with other cluster heads. In infrastructure mode, RSUs are already present. Each and every vehicle communicate with these RSU. In this approach if RSU is present in the coverage area, it works ininfrastructure mode. If RSU is not available, then adhoc mode will be activated.
