Performance Analysis of AODV, DSDV And DSR in Vehicular Adhoc Network (VANET)

Vehicular network is a network where vehicles communicate through an ad-hoc network system which run on the basis of some specific ad-hoc routing protocols. The vehicular ad-hoc network consists of two communication parts known as vehicle-to-vehicle(V2V) communication and vehicle-to-infrastructure(V2I) communication. Though the roads has become very crowded with a lot of vehicles, it has become a crying need to control the movement of the vehicles. Automated traffic control, critical moment notifications, post accidental notifications, correct route selection has become very important and these can be implemented by using vehicular ad-hoc network system. For the proper communication among vehicles, the vehicular ad-hoc network(VANET) uses some protocols. The AODV, DSDV and DSR are the mostly used protocols. In this paper, a performance study of the above mentioned protocols has been stated by applying them on a specific network for some basic criteria such as throughput, delay, jitter, packet ratio, dropped packet, link-losses etc. This study helps to find the protocol which will satisfy the basic needs of a VANET system.
