Survey on Collision Avoidance System in VANET

Abstract

The biggest problem regarding the increased use of private & public transport is the increasing number of accidents on the roads. To overcome this new technology emerged VANET. Vehicular adhoc networks(VANETs)are classified as an application of mobile adhoc network(MANET) that has the potential in improving road safety and in providing travelers comfort. Recently VANET shave emerged to turn the attention of researchers in the field of wireless and mobile communications; they differ from MANET by their architecture, challenges, characteristics and applications. In this paper we present aspects related to this field starting from VANET architecture and ending up with the most appropriate simulation tools to simulate VANET protocols and applications. [1]
