标题： Performance Analysis of IEEE 802.11bn with Coordinated TDMA on Real-Time Applications

摘要： Wi-Fi在连接电子设备和提供日常生活的通信服务中起着至关重要的作用。 最近，对需要低延迟通信的服务的需求不断增加，例如实时应用。 最新的Wi-Fi修订版IEEE 802.11bn正在开发中，以通过多接入点协调（MAPC）等技术满足这些需求。 在本文中，我们证明了协调时分多址（Co-TDMA），MAPC的一种技术，能有效降低传输时间敏感流量的延迟。 特别是，我们关注最坏情况下的延迟和抖动，这些是评估实时应用性能的关键指标。 我们首先介绍一种Co-TDMA调度策略。 然后，我们研究这种调度策略在不同网络拥塞水平和流量体积特性下对延迟的影响。 最后，我们通过系统级仿真验证了我们的发现。 我们的仿真结果表明，Co-TDMA有效缓解了低延迟流量的抖动和最坏情况下的延迟，后者改善了约24%。 显示英文摘要

摘要： Wi-Fi plays a crucial role in connecting electronic devices and providing communication services in everyday life. Recently, there has been a growing demand for services that require low-latency communication, such as real-time applications. The latest amendments to Wi-Fi, IEEE 802.11bn, are being developed to address these demands with technologies such as the multiple access point coordination (MAPC). In this paper, we demonstrate that coordinated TDMA (Co-TDMA), one of the MAPC techniques, effectively reduces the latency of transmitting time-sensitive traffic. In particular, we focus on worst-case latency and jitter, which are key metrics for evaluating the performance of real-time applications. We first introduce a Co-TDMA scheduling strategy. We then investigate how this scheduling strategy impacts latency under varying levels of network congestion and traffic volume characteristics. Finally, we validate our findings through system-level simulations. Our simulation results demonstrate that Co-TDMA effectively mitigates jitter and worst-case latency for low-latency traffic, with the latter exhibiting an improvement of approximately 24%.
