Greedy forwarding mechanism and decomposition areas in urban environment for VANET

Numerous efforts are currently under progress to enhance the safety and efficiency of vehicular traffic through intelligent transportation systems. In addition, the growing demand for access to data and information from human users on the go has created the need for advanced vehicle-to-vehicle and vehicle to roadside communication systems capable of high data rates and amenable to high degrees of node mobility. The importance of inter-vehicle communication is increasing due to its role in organizing road. In this paper we present our proposition witch consisting of a new routing protocol VANET (vehicle AdHoc Network) based on a new mechanism of Greedy Forwarding with a decomposition of zones. This protocol is based on the localization of the node, and also the score assigned to each vehicle and the cost for each junction. We evaluate the performance of our proposition in terms of: End to End Delay, and Delivery Ratio.
