A Study on Improving Performance Of Inter-Vehicle Communication Assisted By Road-Vehicle Communication

This paper reports on a method to improve inter-vehicle communication (IVC) using a communication control scheme based on Carrier Sense Multiple Access (CSMA). The authors explore ways to improve communication using p-persistent CSMA MAC protocol. In p-persistent CSMA, if idle state of the channel is detected, transmission is filled in with the probability of p. The authors maintain that it is possible for p-persistent CSMA to adapt optimally to current packet traffic situation by setting p to an appropriate value. Therefore, improvement of IVC performance is expected if the optimal p value can be set according to real world traffic situations. The authors propose a system in which the traffic monitor on the road side informs the appropriate p value to each vehicle in the area using vehicle-to-roadside communication. They analyze the performance of this system with simulations.
