Recently, vehicular-based highway safety applications have been paid much attention and are of great interest to governments and management authorities. A vehicular ad hoc network (VANET) uses cars as mobile nodes in a MANET to create a mobile network. A VANET provides a potential and promising solution to vehicular safety. Multi-hop broadcasting schemes are particularly preferred in a VANET to disseminate time-sensitive safety warning information to all potentially influenced nodes. However, broadcasting may lead to frequent contention and serious collisions and cause broadcast storms among adjacent nodes. In order to reduce broadcast storm, this paper proposes an optimal forwarder selection scheme to:(1) minimize the number of rebroadcasting nodes, and (2) guarantee fast and efficient safety warning information dissemination towards potentially influenced nodes. The proposed forwarder selection scheme is based on the analytic hierarchy process. The criteria include inter-vehicular lateral and longitudinal distances, vehicular communication ranges, and traffic density. The AHP-based forwarder selection model is established and the model's validity is verified mathematically in this paper.
