Various Approaches of VANET Routing and Attack Detection

VANET basically is the part of MANET that provides feasible communication to the vehicles. The RSUs in the phenomena help the vehicles to easily communicate and hence provide collisions. This paper briefly explains about the attack that occurs in the VANET scenario. In this various routing protocols, attack detection approaches used in VANET have been described. In this network safety message delivery without any delay has to be essential to avoid any collision in the network. On the basis of study of different approaches in VANET best approach can be extracted that can be used for VANET network in real world applications.
