A Novel Approach to Enhance the Security and Reliability of Vanet

VANET is a vehicular ad hoc network where a short-lived network is formed among the VANET nodes. VANET nodes communicate and interchange messages with other vehicular nodes either in an infrastructure or infrastructure-less network. Due to lack of fixed infrastructure, VANET is prone to varied attacks. In impersonation attack, identity of the legitimate node is stolen by an attacker. As per proposed work we have defined the network with a new intelligent algorithm to perform the vehicle to vehicle communication. Each vehicle can pass the information to other regarding the path, speed etc. This information also includes the accident status also. In this proposed work, CA will verify all vehicles and give instructions to RSU’s according to their status. This schema will be based upon HASH value and steganography.
