Investigation of Effective Region for Data Dissemination in Road Networks Using Vehicular Ad hoc Network

Dissemination of data related to dynamic and timely traffic / road condition, and any unexpected events can significantly improve the quality of driving with respect to time, distance, and safety. Although extending region of data dissemination in the network constructed among vehicles informs more vehicles on road network, it increases communication cost and imposes delay on the network. The imposed delay has an undesirable impact on vehicle safety applications which require very low message latencies. This research investigates how communication cost and additional travel cost are affected while the region of dissemination is increased. Moreover, this research aims at studying the effective region for data dissemination in an ad-hoc network among vehicles. The simulation results indicate that extending the region of data dissemination increases the communication cost and decreases the additional travel cost. Also, there is an optimal region for data dissemination so that effective propagation of data to a certain area reduces the additional travel cost.
