Abstract

We consider the simplest IEEE 802.11 WLAN networks for which analytical models are available and seek to provide an experimental validation of these models. Our experiments include the following cases: (i) two nodes with saturated queues, sending fixed-length UDP packets to each other, and (ii) a TCP-controlled transfer between two nodes. Our experiments are based entirely on Aruba AP-70 access points operating under Linux. We report our observations on certain non-standard behavior of the devices. In cases where the devices adhere to the standards, we find that the results from the analytical models estimate the experimental data with a mean error of 3–5%.
IEEE 802.11网络分析性能模型的实验验证
我们考虑了最简单的IEEE 802.11 WLAN网络,其中有可用的分析模型,并试图提供这些模型的实验验证。我们的实验包括以下情况:(i)两个节点具有饱和队列,相互发送固定长度的UDP数据包,以及(ii)两个节点之间的tcp控制传输。我们的实验完全基于在Linux下运行的Aruba AP-70接入点。我们报告了我们对设备某些非标准行为的观察。在设备符合标准的情况下,我们发现分析模型的结果估计实验数据的平均误差为3-5%。
