DIFFERENT APPROACH FOR SECURE COMMUNICATION OF VANET OVER DSRC WITH 802.11

Mobile Ad - Hoc network research has been gaining in last few years. Lot of work has been put into devising routing protocols and secure communication with the development 802.11p standard dedicated to DSRC.VANET is very close to such research. VANETs must be tested thoroughly before they are put in real world as the consequences of failing systems are very high in VANETs. There exist a few simulators like Groove Sim, NS, Which can be used for VANETs but given the popularity and well spread knowledge of MATLAB tool, a simulation environment in MATLAB could be very useful to many researchers. Such environment can be used while designing better MAC protocols, broadcasting schemes, security features in VANETs. In this paper we are surveying different approach like Privacy - preserving schemes, ID - Ba sed Cryptography (IBC), Ad Dissemination Model, FRAMEWORK etc. for secure communion in VANET. Simulation and testing was performed almost in MATLAB.
