Abstract(in English) Inter-vehicle communication is required to be real-time and to be adaptive to the dynamic network topology changes caused by the movement of vehicles. In this paper, we propose a protocol for inter-vehicle communications that reduces the delay and forms reliable vehicle networks. The proposed scheme extends contention type protocol which forms network dynamically adaptive to vehicle network topology changes. It reduces the delay and increases the number of vehicles that can transmit a flame within maximum transmission interval by controlling carrier sensing interval according to the vehicle density. Finally, simulation evaluates the proposed scheme from the viewpoint of average delay and transmission success rate and clarifies the effectiveness of the proposed scheme.
