Abstract
This paper presents an intelligent vehicle safety system, constructed by exchanging emergency-related information such as urgency stop, traffic accident, and obstacles between vehicles. In the majority of vehicle safety communication applications, an emergency message is propagated in the form of broadcasts. However, this causes numerous problems, such as massive radio collision, multi-hop propagation and fast relay. This paper presents a selective message forwarding method by proposing a stem and branch structure based on prospected positions. The logical structure makes it possible to assign a representative vehicle to relay an emergency message among the different level of wireless radio coverage. The proposed scheme improves the efficiency of message transmission with the selective priority for forwarding messages by distance. The structure also limits the number of broadcasting hops. The proposed method is evaluated using a network simulator.
