In vehicular networks, road safety and data-related applications require reliable and efficient communications with minimized transmission collisions, and thus effective medium access control (MAC) protocols are also essential for the VCN system design. However, in vehicular networks, the MAC design is much more challenging due to the high mobility, heterogeneous and frequently changing topology, and versatile QoS requirements. Hence, also following the wireless-vehicle combination perspective, in this chapter, we focus on the effective and efficient MAC designs for VCN. First, by taking the trend (from distributed to centralized) and challenges of the MAC design in VCN into consideration, three essential MAC issues and their corresponding solutions are explored, including distributed congestion control, centralized resource sharing and scheduling, and centralized data dissemination scheduling. Then, regarding the next leap for MAC designs in VCN, NOMA-V2X and data-driven resource management are also discussed.
