Performance analysis of various routing protocols for VANET environments

Abstract

Vehicular Adhoc Network (VANET) is a fast emerging and new technology that are derived from adhoc networks to provide intelligent vehicle to vehicle communication and to improve the road safety and other on road facilities. VANETs are distinct from other networks in terms of high speed movements of vehicles, unpredictable nature of vehicular density over time and specific mobility patterns associated with different scenarios. Hence designing a suitable routing protocol for VANET applications is a very critical and specific task and it is different from that of MANETs even though VANETs are derivatives of the former. In this work we discuss and compare the effectiveness of routing protocols such as, AODV, DSR and DYMO with respect to three parameters namely, throughput, average end-end delay and average jitter. The simulations were carried out in Qualnet 5.0 network simulator. From the obtained results it is concluded that DYMO edges out the other two protocols in terms of the above mentioned metrics when it comes to VANET scenarios.
