  • Abstract The international medium access control (MAC) standard for the vehicular ad hoc network (VANET), IEEE 802.11p, provides two channel access schemes to support quality-of-service (QoS): one is EDCA (enhanced distributed channel access) and the other is HCCA (hybrid controlled channel access). Previous studies have shown that HCCA outperforms EDCA especially for real-time multimedia traffic transmissions. However, HCCA can work only in a wireless environment with access points. To support QoS in a VANET, previous schemes tried to construct clusters and let the cluster-head play the role of an access point. However, such an approach consumes large amount of bandwidth on cluster-related operations, including cluster-head election, cluster-head handover, cluster mergence, and cluster channel switch etc. To overcome these drawbacks, we design a new cluster-based MAC protocol, named RC-MAC, which can mimic the operations of HCCA without consuming bandwidth on maintaining clusters and cluster-heads. Hence it is expectable that the protocol overhead of RC-MAC is low. The simulation results show that, in terms of throughput and delay, RC-MAC significantly outperforms existing cluster-based MAC protocols.
