摘要

近年来，随着许多新兴的无线局域网应用和服务的出现，对高速无线局域网的需求急剧增长。然而，众所周知，IEEE 802.11介质访问控制(MAC)具有很高的开销。为了提高系统的效率，新的IEEE 802.11e MAC引入了Block ACK方案。在本文中，我们从数学上分析了802.11e块ACK方案在考虑块ACK保护方案的噪声信道上的吞吐量和延迟性能。然后，用ns-2模拟对数值结果进行了验证。

Throughput and Delay Analysis of IEEE 802.1le Block ACK with Channel Errors

Recently, along with many emerging applications and services over Wireless LANs (WLANs), the demands for higher-speed WLANs have been growing drastically. However, it is well known that IEEE 802.11 Medium Access Control (MAC) has a high overhead. As a solution to improve the system efficiency, the new IEEE 802.11e MAC introduces Block ACK scheme. In this paper, we mathematically analyze both throughput and delay performances of the 802.11e Block ACK scheme over a noisy channel considering the Block ACK protection scheme. Then, the numerical results are verified with ns-2 simulations.
