In this paper we proposed a novel self-organized message dissemination algorithm, namely the Cluster-based Broadcast (CB), for the Emergency Electronic Brake Light (EEBL) application in Vehicular Ad-hoc Networks (VANET). The proposed cluster-based broadcast algorithm converts multihop broadcast message forwarding into multiple of single-hop broadcast clusters, which offers higher reliability, lower channel usage and message propagation delay in comparison with the traditional Directional Flooding (DF). Furthermore, we study the dependence of EEBL application on the market penetration ratio of the VANET wireless communication nodes. An innovative idea of combining the VANET with nomadic devices is proposed in this work to mitigate the slow market penetration rate problem. The results show that the nomadic devices, like portable navigation devices with communication ability, will play an important role when the VANET technology is rolling out in our real life.
