摘要

Most Vehicular Ad Hoc Networks' (VANET) applications use broadcasting as a main block for safety messages' dissemination. The broadcast range is a critical parameter in the success of any VANET's safety application. Moreover broadcasting in its normal way may lead to a broadcast storm problem. In this paper we present a geometric model to predict the recommended maximum range of a one hop broadcast message. We also introduce a new scheme to alleviate the impact of the broadcast storm problem taking into account the network topology and traffic parameters. Our simulation results show that the proposed scheme provides higher reception rates and lower message travel time compared to the existing solutions.
