Abstract:
Safety is one of the most important issues in VANETS. It includes collision avoidance systems and alert dissemination applications. In this paper we focus on the second issue because the availability of the traffic road information in time can enlarge the conductorâ€™s visibility. Classical solutions are based on the well known flooding strategy which uses multi-hop broadcast to reach a large number of vehicles. Their main concern is how to decrease the number of relay nodes because this is the key to reduce broadcast storm effects. The majority of existing solutions discards the use of unicast messages. The contribution of this paper consists essentially in using both the unicast and the broadcast modes. Simulation shows that the proposed protocol achieves low latency in delivering alerts.
