Wireless Local Area Network Service Quality Assurance Protocol Based on Cross-Cell Target Wake-up Time

Due to the rapid development of wireless network communications, this paper makes certain improvements to the Target Wake-up Time (TWT) mechanism adopted based on the IEEE 820.11ax standard protocol, and proposes a Wireless Local Area Network (WLAN) based on cross-cell TWT Service Quality Assurance Agreement. First, the wireless Access Point (AP) sleep mechanism is introduced, and then through the TWT mechanism, the AP arranges sleep time for the STA and informs the STA of its own sleep time. This mechanism further reduces energy consumption, and then introduces the cooperative APs. This concept ensures that high-priority services generated by the STA during the AP sleep process can be forwarded in time, thereby ensuring service quality. Through relevant simulation verification, the results show that the implementation of this solution effectively ensures the quality of communication services, especially network delay.
