Low-Latency Guarantee Protocol Based on Multi-links Scheduling Random Access in the Next Generation WLAN: IEEE 802.11be

With the advent of artificial intelligence and big data era, the demands for wireless networks require increasingly high quality of service (QoS). In the next-generation wireless local area network (WLAN), the Institute of Electrical and Electronics Engineers (IEEE) 802.11 regards low-latency guarantee as one of the main technical goals. Multi-link operation (MLO) technology can effectively guarantee network delay. Based on this, this paper proposes a low-latency guarantee protocol based on multi-link scheduling random access. The specific process of the low-latency guarantee protocol is proposed and designed, and the frame format of the protocol is designed to make it compatible with the 802.11 frame format. The simulation results show that the random access protocol based on multi-link scheduling can effectively improve the QoS of the network compared with the traditional single link. It not only increases the throughput of the network, but also effectively reduces the data transmission delay. The addition of scheduling algorithms can effectively reduce the delay of high-priority services and reduce the packet loss rate of the entire network.
