Vehicular Ad-hoc Networks (VANET) are considered a promising application in Intelligent Transport Systems (ITS). It is characterized by a high mobility, a high density of nodes, and a very constrained topology that require a more suitable and more reliable routing protocol. Hence, the need to optimize the current routing protocols used in Mobile Ad-hoc Networks (MANET), in order to increase their performance in VANET. Broadcast communication method remains a very important step to adapt the broadcast information to other nodes and to select the routes in better conditions. In this article, we propose a new broadcast approach based on the neighborhood broadcasting methods. Based on this solution, we present an improving Ad-hoc On-Demand Distance Vector Routing (AODV) to reduce the number of dropped packets, and minimize network overhead. The simulation shows encouraging results of our …
