Traffic Evaluation of Group Communication Mechanism among Vehicles

In recent years, much work has been done on ITS, which is proved to be an effect method to improve transport system. In this paper, we focus on improving the safety of driving vehicles by a novel effective communication system. We consider a consensus formation on vehicle group. We propose WDDP (wireless direct distribution protocol) that has a group communication mechanism among vehicles. After comparing several methods with the proposal of group communication mechanism among vehicles in this paper, we discuss the characteristics of packet traffic and number of group nodes as comparison items. We define a simulation model using the communication network simulator, OPNET Modeler. Then, we analyze network traffic on the simulation model and evaluate basic properties.
