VANET: Routing Protocols, Security Issues and Simulation Tools

Abstract

Since the last few years VANET have received increased attention as the potential technology to enhance active and preventive safety on the road, as well as travel comfort. Several unexpected disastrous situations are encountered on road networks daily, many of which may lead to congestion and safety hazards. If vehicles can be provided with information about such incidents or traffic conditions in advance, the quality of driving can be improved significantly in terms of time, distance, and safety. One of the main challenges in Vehicular ad hoc network is of searching and maintaining an effective route for transporting data information. Security and privacy are indispensable in vehicular communications for successful acceptance and deployment of such a technology. The vehicular safety application should be thoroughly tested before it is deployed in a real world to use. Simulator tool has been preferred over outdoor experiment because it simple, easy and cheap. VANET requires that a traffic and network simulator should be used together to perform this test. In this paper, the author will make an attempt for identifying major issues and challenges associated with different vanet protocols, security and simulation tools.
