A Millimeter-wave Multi-channel MAC with Dynamic Spectrum Access Capability for Mobile Self-organizing Heterogeneous Networks

With the rapid development of wireless network technology and the demand for interconnection of mobile edge computing, the integration of heterogeneous wireless networks is becoming more and more urgent. At the same time, the increasing scarcity of spectrum resources also requires heterogeneous net-works to effectively improve the utilization of spectrum resources without affecting the use of different licensed spectrum resources. This paper proposed a multi-channel millimeter-wave (mmWave) MAC protocol for mobile self-organizing heterogeneous networks. The mmWave Mac uses a bulk access transmission scheme to improve throughput efficiency and reduce latency for heterogeneous networks. In addition, cognitive radio technology is also introduced into the mmWave Mac to enhance the utilization of spectrum resources. Finally, by comparing the simulation results with other protocol, it is verified that the mmWave MAC protocol has good performance in terms of delay, and throughput efficiency.
