Distance Based Routing Protocol
ABSTRACT Vehicular Ad-Hoc network mainly involves Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I)communication. This communication facilitates in reducing number of accidents, avoiding traffic congestion, enhancing the transport facility with the aid of infotainment and entertainment application. One of the major challenges of VANET application is in routing the packet in efficient and effective manner since the network topology is dynamic. Distance Based Routing (DBR) protocol designed especially for Vehicular Ad hoc Networks (VANET).DBR algorithm adopts both position based and map based routing technique. In DBR, a connectivity graph based on the inter-vehicular distance, the duration of connectivity between neighbouring vehicles and the information from the digital map are collectively used to route the data. In DBR protocol the network traffic is reduced due to the relative position information of the neighbouring vehicle. The stability of the route path is high due to inter-vehicular distance based next hop selection technique as implemented in this protocol. This routing protocol is simulated using NS2 simulator to analyze the efficiency and effectiveness of the protocol.

Chapter 1 INTRODUCTION 1.1 Background Vehicular ad hoc networks (VANETs) are self-configuring networks where the nodes are vehicles (equipped with onboard computers), elements of roadside infrastructure, sensors, and pedestrian personal devices. Wi-Fi (IEEE 802.11-based) technologies are used for deploying such kind of networks. At present, the IEEE group is completing the IEEE 802.11p and IEEE 1609 final drafts, which are known as “Standard Wireless Access in Vehicular Environments”(WAVE), specifically designed for VANETs. This technology presents the opportunity to develop powerful car systems capable of gathering, processing, and distributing information. For example, a driver assistance system could collect accurate and up-to-date data about the surrounding
