IEEE 802.11ax利用帧聚合和压缩块重传来减少MAC开销并增加有效吞吐量。我们分析了IEEE 802.11ax帧聚合在易出错的环境中,并提出自适应地限制MPDU的大小。这导致MAC帧仍然足够小以具有高传输成功率。使用离散事件模拟器ns-3的性能研究说明了所提出的方法的好处。我们发现,一个高的重传率的结果在低利用率的确认窗口,并讨论其主要的负面影响的有效吞吐量。我们的延迟相关的研究进一步表明,MAC机制,如严格的排序,有助于增加延迟,由于线头阻塞,特别是在高错误率的条件下。我们的结论是,减少延迟,较小的MPDU是有益的。
IEEE 802.11ax utilizes frame aggregation and compressed block acknowledgements to reduce the MAC overhead and to increase the goodput. We analyze IEEE 802.11ax frame aggregation in error-prone environments and propose to adaptively limit the MPDU size. This results in MAC frames that are still small enough to have a high transmission success rate. A performance study using the discrete-event simulator ns-3 illustrates the benefits of the proposed approach. We find that a high retransmission rate results in a low utilization of the acknowledgment window and discuss its major negative impact on the goodput. Our delay-related studies further show that MAC mechanisms like strict ordering contribute disproportionally to increased latency due to head-of-line blocking, especially under high error rate conditions. We conclude that for decreased delays, smaller MPDUs are beneficial.
