Abstract : In this paper, we have minimized the problems for Vehicle to Vehicle communication, caused by the speed of the cars, the obstruction caused by high rise buildings and routing loop problem at the road junction. This causes less throughput and data packet drops for a given network. In order to avoid these problems, we have defined a set of fixed junction points (FJP), any particular vehicles around FJP, is assigned as a transceiver for the data communication. That vehicle, called Virtual junction point (VJP) which has assigned weight to every road, depends on number of cars on that road and the distance between two junctions points along that road. Apart from the concept of VJP, a newly developed method, we call it Center of Mass (CM) method, is used by source vehicle for selecting the next forwarding vehicle. In this method, one minimizes the sum of all the distances of all neighboring vehicles from a given imaginary point, which is the CM point. In this point, physically there may not be any vehicle, but the vehicle close to that point is used for the next forwarding vehicle in our method. Simulation result shows our method performs better than other protocols.
