Adaptive Message Passing Scheme in VANET

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 xed equipment, usually described as roadside equipment. In VANET, or Intelligent Vehicular Ad-Hoc Networking, de nes an Intelligent way of using Vehicular Networking. VANET integrates multiple ad-hoc networking technologies such as WiFi IEEE 802.11 b/g, WiMAX IEEE 802.16, Bluetooth, IRA, ZigBee for easy, accurate, e ective and simple communication between vehicles on dynamic mobility. A vehicle in VANET is considered to be an intelligent mobile node capable of communicating with its neighbors and other vehicles in the network. The goal of the projects is to create new network algorithms or modify the existing for use in a vehicular environment. In the future vehicular ad hoc networks will assist the drivers of vehicles and help to create safer roads by reducing the number of automobile accidents. In the current project we will focus on hybrid model of cluster based VANET and infrastructure based VANET. In adhoc mode, only clusters are present with each cluster having cluster head. Also all cluster members of each cluster communicate with cluster head. These cluster head communicate with other cluster heads. In infrastructure mode, Road Side Units (RSUs) are already present and each and every vehicle communicate with these RSU. In this report we will propose hybrid model, where by in city areas, infrastructure mode will be used and when vehicle moves to highway where RSUs may not be available then in that case, infrastructure mode will switch to ad-hoc mode.
