Design and Implementation of Efficient Authentication Agent to Reduce Number of Hops in VANETS

Vehicular ad hoc network (VANET) is a network built among vehicles. Vehicular ad hoc network is attaining importance as it enhances the safety of passenger and also provides extra services which are useful to user. The key factor for success of VANETs lies in its mobility. VANETs are utilized by many users hence there is a need to provide authentication and authorization. PMIPv6 provides efficiently authentication and authorization. But it suffers from man in middle attack. It also impedes localized advantage due to long distance delivery. Billing is also a important issue in VANET which has been not focused in past. VANET is a network made up of different users hence it is difficult to motivate users to cooperate for data transmission. This project provides authentication in faster manner by making use of mutual authentication. It provides effective billing scheme. It motivates each vehicle in VANET to participate in transmitting data by providing incentive to them. It prevents the man in middle attack with the help of encryption. It uses a Proxy server which reduces the number of hops required to transmit the data.
