Multi-Priority MAC Protocol for Terahertz Wireless Local Area Network

In order to solve the problem that IEEE802.15.3c protocol is designed without considering the characteristics of large traffic network environment in terahertz wireless local area network, a multi priority MAC(MP-MAC) protocol is proposed. The MP-MAC protocol uses a backoff algorithm to determine data priority based on nodes and services, dynamically divides Channel Time Allocation (CTA), and uses a backpack algorithm to allocate time slot resources in a competitive access period (CAP). Simulation results show that under the condition of high load, compared with other protocols, this protocol can reasonably allocate time slot resources, has better network performance, and ensures the quality of service of high priority services.
