Abstract In Vehicular Sensor Networks (VSNs), road safety applications are important to ensure the safety of motorists by broadcasting alert messages in this network. The dissemination process is the use of adaptive broadcasting algorithms that make efficient use of vehicular communications avoiding the problem of broadcast storms. Therefore, an effective warning message broadcast protocol should represent the appropriate transmission node for each message, maximizing the number of vehicles informed by the hazard of the situation, while simultaneously reducing the time needed to inform them and the amount of traffic generated in the wireless channel. In this work, we propose safety messages dissemination protocol based on QoS metrics as delay, link quality and flow for the choice of a reliable, fast and efficient broadcaster. Our experiments proved the efficiency of our proposal compared to other existing solutions in the literature and using the OMNETT ++ simulator. © 2019 IEEE.
