The Internet of vehicles (IoV) is an emerging networking technology, which can support information sharing and interactions among users, vehicles, and infrastructures. Various applications can be provided by IoVs, and they have very different quality-of-service (QoS) requirements. It is a great challenge to design an efficient MAC protocol to meet the different QoS demands of various applications in IoVs, because of unreliable links and high vehicle mobility. On the other hand, cooperative communication is effective in mitigating wireless channel impairments by utilizing the broadcast nature of wireless channels. In this paper, a multi-channel cooperative clustering-based MAC (MCC-MAC) protocol, under the Dedicated Short Range Communication (DSRC) multi-channel architecture, is presented to improve the transmission reliability of safety messages and provision QoS for different applications in IoVs. Further, we analyze the performance of MCC-MAC, in terms of average transmission delay. In addition, extensive simulations with ns-2 are conducted to demonstrate the performance of the proposed MCC-MAC.
