An intelligent vehicle safety system can be constructed by exchanging emergency-related information between any unrelated vehicles, such as urgency stop, traffic accident, and obstacles. In the most of vehicle safety communication applications, an emergency message is propagated in the form of broadcasting. However, it causes a lot of problems in terms of efficiency due to the multi-hop propagation and radio collision problems. This paper presents a selective message forwarding method by proposing the stem and branch structure. With benefit of the structure, only one vehicle performs forwarding a received emergency event among the vehicles that are included in the same wireless coverage. Moreover, the proposed scheme improves the efficiency of message transmission with the selective assignment of priority for forwarding message. To analyze its performance, it has been evaluated by network simulator. © Springer-Verlag Berlin Heidelberg 2006.
