Abstract:In order to ensure traffic safety, the emergency warning message should be transmitted quickly and reliably in vehicular ad hoc networks by multi-hop broadcast. In this article, we propose a traffic flow theory-based dynamic multi-hop broadcast protocol to address the issue of emergency warning message dissemination in vehicular ad hoc networks. The main goal of our protocol is to reduce delay and enhance reliability no matter the traffic density is high or low. First, according to the simulations of the distr… Show more
