Performance Evaluation of Routing Protocols in VANET System for Congestion Detection

Abstract

VANETs (Vehicular Ad-hoc Networks) are an emerging new technology which integrates the capabilities of new generation wireless networks to vehicles. It includes a variety of applications such as safety application, Mobility, Convenience and Internet Access Applications. Because of the high nodes mobility and unreliable channel conditions, VANETs have unique characteristics which pose many challenging research issues. This work is mainly focused on routing protocol for VANETs. The main requirement of routing protocols is to achieve minimal communication time with minimum consumption of network resources. Many routing protocols have been developed for VANETs (Vehicular Ad-hoc Networks), such as AODV (Ad-hoc On demand Distance Vector) and DSDV (Destination Sequence Distance Vector). The main aim of this work is to evaluate two different routing protocols (AODV and DSDV) in terms of Packet Delivery Ratio (PDR), average Delay and throughput by using MOVE and SUMO to generate mobility model and NS-2 to evaluate these protocols. Simulation results showed that AODV is better for VANET system because in AODV there is no need to maintain route table, which results in less bandwidth consumption.
