Vehicular networks have great interest in the research community and multihop data dissemination has become an important issue. Vehicular adhoc network is a type of mobile adhoc network, in which mobile nodes forming temporary or short lived network without any fixed infrastructure. This paper proposed the concept of data dissemination from source to destination with the traffic model in vehicular networks. The GPSR protocol can be used for data dissemination, GPSR uses a greedy forwarding algorithm that will send the information to the final destination using the most efficient path possible. If the greedy forwarding fails, perimeter forwarding will be used to find routes around the perimeter of the region.
