Simulation and Analysis of AODV Routing Protocol in VANETs

Abstract

Recent advances in wireless networks have led to the introduction of a new type of networks called Vehicular Networks. Vehicular Ad Hoc Network (VANET) is a form of Mobile Ad Hoc Networks (MANET). VANETs provide us with the infrastructure for developing new systems to enhance driversâ  and passengersâ  safety and comfort. VANETs are distributed self organizing networks formed between moving vehicles equipped with wireless communication devices. This type of networks is developed as part of the Intelligent Transportation Systems (ITS) to bring significant improvement to the transportation systems performance. As the necessity of such network increases the implementation challenges are being taken into account. They are broadcasting, routing, priority scheduling and security and privacy. In this paper the routing is considered as the research factor. Many routing protocols have been proposed and assessed to improve the efficiency of VANET. Previous studies of VANET showed that the Ad hoc On-demand Distance Vector (AODV) has the highest efficiency in topology-based protocols. In this thesis simulation of AODV is done on simulators which allow users to generate real world mobility models for VANET simulations. For this MOVE is used along with SUMO and NS2. MOVE tool is built on top of SUMO which is open source micro-traffic simulator. Output of MOVE is a real world mobility model and can be used by network simulator NS-2. In this thesis we analyze and evaluate the performance of AODV under different node densities. Three different sets of node density would be used to compare the performance of the said protocol. Simulation results obtained in the form of graphs are then compared under various parameters like throughput, packet size, packet drop, End to End delay etc.
