PERFORMANCE EVALUATION OF DSDV, AODV ROUTING PROTOCOLS IN VANET

Abstract

Wireless networks between vehicles formed by VANET (Vehicular Ad hoc Networks). VANET incorporates the wireless communication and data sharing capabilities to turn into vehicles as a network topology. VANET is showing great potential in research area. Inter-vehicle communication system in VANET improves traffic safety. VANET consists of high dynamic topology, Intermittent connectivity Patterned mobility and on board sensors etc. A challenging task in vehicular ad hoc network is routing of data due to its high dynamic behavior. An efficient routing protocol by understanding the dynamic behavior of VANET topology will plays an essential role in communication of vehicles. Mobility of nodes, road topologies are some of the internal factors are presented on the performance of routing protocols. Routing protocols are of mainly categorized into: Proactive, Reactive and Hybrid routing protocols. This paper occurs with performance evaluation of AODV (Ad-Hoc on-Demand Distance Vector), DSDV (Destination-Sequenced Distance Vector) routing protocols using mobility model IDM-IM (Intelligent Driver Model with Intersection Management, this mobility model is from VanetMobisim) based on metrics such as packet delivery ratio, throughput and average end to end delay. AODV is reactive routing protocol and DSDV is proactive routing protocol. IDM_IM is the VanetMobisim tool mobility model with a simulation area. In this paper we also present how the VanetMobisim interacts with Network Simulator. VanetMobisim presents results as a text file. The simulation results are presented with graphs. VanetMobisim and Network Simulator tools are open access tools. VanetMobisim a vehicular ad hoc network tool and network simulator-2(NS2) a simulation tool are used for implementation purpose.
