VANET: Vehicle to Vehicle wireless communication system with effective multi-hop routing

Abstract

Vehicular ad-hoc Network (VANET) is an emerging type of network that base on Wireless Access for Vehicular Environments (WAVE) standard and also it's a special type of network in Mobile ad-hoc Networks. VANET is also known as IEEE 802.11p and its required to support the Intelligent Transportation Systems (ITS) applications in the short range communications in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. Since VANET has its unique network characteristics, the performance of communication depends on how better the routing takes place in the network and routing of data depends on the routing protocols being used in network. So In this thesis I analyzed available simulation approaches for the VANET and proposed OPNET as reliable best solution for VANET simulation and studied and highlights OPNET techniques to simulate VANET with Network and Mobility models. Also I evaluate four routing protocols AODV,OLSR,GRP and Modified AODV as Reactive, Proactive and Hybrid Routing Protocols to compare their performance on VANET using this simulator. Finally this thesis proposes a solution for VANET routing and it's a modified version of the standard AODV protocol. This proposed Optimized Cost aware AODV protocol is based on optimum route cost to enhance the efficiency of the conventional AODV.
