摘要

为了提高无线局域网在衰落信道中的性能，基于IEEE 802.11分布式协调函数(DCF)，提出了一种新的分布式协调函数(DCFf)方案。提出了一种考虑帧误差的分析模型来分析DCF和DCFf的饱和吞吐量。我们探讨了在基本接入模式下，帧错误、数据速率和网络大小对两种算法性能的影响。分析结果表明，该算法在无线衰落信道中的性能优于DCF算法

Throughput enhancement of the IEEE 802.11 DCF in fading channel

Based on the IEEE 802.11 distributed coordination function (DCF), a novel scheme named DCFf is proposed to improve the performance of wireless local area network (WLAN) in fading channel. An analytical model considering frame errors is presented to analyze the saturation throughput of DCF and DCFf. We explore the effect of frame errors, data rate and network size on the performance of both algorithms in the basic access mode. The analysis results show that our DCFf performs better than DCF in wireless fading channel
