摘要：In IEEE802.11p protocol, multiple channels are assigned to Vehicular Ad-hoc network (VANET), the licensed spectrum of 5.850GHz-5.925GHz is divided into one control channel (CCH) and six service channels (SCHs). So that the mechanism of channel access control has great influence on communication efficiency of VANETs. We propose a channel access control mechanism, which integrates channel reservation algorithm with contention based Distributed Coordination Function (DCF) and contention-free Time Division Multiplexing Access (TDMA) to coordinate channels' access between CCH and SCHs. The analysis results show that the proposed mechanism not only can dynamically adapt network load conditions, but gives consideration to communication efficiency both in CCH and SCHs, high throughput can be obtained even in heavy load VANETs.
