这篇论文基于隧道占有时间(简易窄床) 建议一个新隧道存取算法保证公平并且改进 802.11b 多率 WLAN 的总数产量的公平。在算法, COT 被用作公平索引分析 WLAN 的公平而不是在分布式的协作函数(DCF ) 使用的隧道存取概率(帽子) 。标准简易窄床被存取点(AP ) 给并且广播到所有无线车站。在 WLAN 的 AP 和无线车站能由调整他们的包长度完成基于简易窄床的公平,同时送多重紧接的包,或放弃一个机会存取隧道。分析和模拟证明我们的算法能提供简易窄床公平。与基于帽子的算法相比,建议算法在 IEEE 802.11b 多率 WLAN 的总数产量导致改进。
This paper proposes a new channel access algorithm based on channel occupancy time (COT) fairness to guarantee fairness and improve the aggregate throughput of 802.11b multi-rate WLANs. In the algorithm, the COT is used as fairness index to analyze the fairness of WLANs instead of the channel access probability (CAP) used in the distributed coordination function (DCF). The standard COT is given by access point (AP) and broadcasted to all wireless stations. The AP and wireless stations in the WLAN can achieve COT-based fairness by adjusting their packet length, sending the multiple back-to-back packets at one time, or giving up an opportunity to access the channel. Analysis and simulations show that our algorithm can provide COT-fairness. Compared with the CAP-based algorithm, the proposed algorithm leads to improvements in aggregate throughput of IEEE 802. lib multi-rate WLANs.
