Abstract :
In this paper, improving DS/SS inter-vehicle communication using p-persistent CSMA MAC protocol is studied. 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 optimal p value can be set according to the traffic of vehicles. In order to perform this, the scheme where the traffic monitor on the road side informs the appropriate p value to each vehicle in the area using road-vehicle communication is proposed and its performance is analyzed by simulations.
