Throughput enhancement of the IEEE 802.11 DCF in fading channel
Xiaohui Xu, Xiaokang Lin · 2006
Based on the IEEE 802.11 distributed coordination function (DCF), a novel scheme named DCFfis 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 DCFfperforms better than DCF in wireless fading channel
