%X <p>Due to the shortages of the analytical model and simulation model, hierarchical stochastic colored Petri net has been proposed to model the media access control layer of IEEE 802.11p, which is used for investigating the broadcast performance of vehicular ad hoc networks. The proposed model has been used to describe the generation, retransmission, backoff and internal collision process. Then, the performance metrics have been simulated and analyzed. The results show that the higher priority access category has the shorter time delay and delay jitter. Moreover, the operation of the IEEE 802.11p can be intuitively understood by using the hierarchical stochastic colored Petri net(HSCPN) model, which is helpful for the protocol improvement, and it can also provide theoretical basis for the deployment of VANETs.</p>
