Modeling and simulation of VANET in traffic city

Vehicle-to-vehicle communication is a very actual and challenging topic which attracts a considerable attention from there search community. Vehicles are able to exchange information within these networks without the need of installing any infrastructure along the road side. To evaluate a Vehicular Ad Hoc Networks (VANETs) in traffic city, we present a simple model of simulation based on a Cellular Automaton technique specified by the rules which control communication exchange and the mobility of vehicles. Moreover, in a Cellular Automaton, space and time are divided into discrete cells and steps which can reduces the complexity of the system and cost of deployment. The model used here is based on the cellular automata(CA) model proposed by Biham-Middleton-Levine(BML). It considers two kinds of drivers which obeys the traffic light rules. Each vehicle generates an amount of data and hope to send it to the base station (BS) located in the middle of the network. In this work, we examine the performance of VANET in terms of average throughput. Simulation results show that the traffic patterns have an important impact over data communication at the base station as well as in the whole capacity of the communication network.
