Description
Summary:Since IEEE 802.11p has been adopted as Vehicular Ad hoc Networks (VANET) main technology, the research and development of vehicular safety applications has gained momentum. Because broadcasting is the predominant traffic type in VANETs, their safety applications will face a challenge in managing the channel capacity to insure good performance in terms of throughput, delay, fairness and broadcast coverage. In this paper we analyze the performance of the broadcast scheme of IEEE 802.11p standard analytically and verify the model by simulation. We then derive the optimal values of its parameters considering the probability of packets successful reception, throughput, delay and collision probability in a harsh vehicular environment.
