Vehicular ad hoc networks (VANETs) are a special type of mobile ad hoc networks (MANETs), where nodes are moving vehicles that communicate with one another wirelessly. The promising technology of VANETs will enable variety of applications from safety to driver assistance. Routing protocols that work efficiently in MANETs perform poorly in VANETs due to high-speed mobility of nodes, resulting in frequent wireless link breakage. Broadcasting is a critical factor for data dissemination in a multi-hop wireless network such as VANETs. The purpose of this study is to alleviate the broadcast storm problem in VANETs by proposing a novel broadcast scheme. The proposed broadcast scheme extracts certain parameters such as SNR from the received message and using that to locally determine whether to rebroadcast. Simulation results show the ability of the proposed communication scheme is significantly alleviating the broadcast storm problem by up to 80%. The value of this work resides in carrying the Emergency Warning Messages (EWM) to vehicles in a geographical region while reducing number of collisions and delay.
