摘要：
Traffic safety and efficiency are the most important motivations for the rapid development of vehicular ad hoc network (VANET) technology. VANET is considered to provide the unified platform and solutions for the intelligent transportation system (ITS). In this paper, a novel method named spectrum penetration is proposed to improve the throughput of multi-channel MAC for VANET. Meanwhile, it can overcome the drawback of multi-channel hidden terminal problem by performing cross channel data exchange. The proposed spectrum penetration based multi-channel MAC (SPBM) protocol makes full use of the seven channels and idle subcarriers specified in the IEEE 802.11p to ensure the timely safety message broadcast and improve the throughput of non-safety messages. The simulation results demonstrate that our proposed SPBM protocol has a high channel utilization and strong adaptability to different traffic densities.
