Abstract: VANET is a special kind of MANET. It will provide communication between vehicles and fixed units and also among the vehicles . VANETs are mainly used for Traffic optimization and improving safety. Due to open nature of wireless medium, a lot of attacks are possible in vanet. In this paper we propose a method to reduce the overload of DMV and vehicle. To improve the computation overhead in DMV, we use 2 hash values and location of vehicle. In the case of vehicle we use co-operative message authentication method.
