關鍵字: | DCF; IEEE 802.11 WLAN; Performance analysis | 公開日期: | 2008 | 卷: | 7 | 期: | 11 | 起(迄)頁: | 4425-4431 | 來源出版物: | IEEE Transactions on Wireless Communications | 摘要: | In this paper we investigate the throughput performance of IEEE 802.11 Distributed Coordination Function (DCF) in the presence of physical-layer (PHY) inequality, i.e. varied channel conditions and/or unequal data rates determined by the Link Adaptation (LA) scheme. We present a theoretical model for DCF protocol with the LA scheme of AutoRate Fallback (ARF). The analysis results show that the system throughput of DCF-based WLANs is determined by the lowest data rate used with stations; throughput sharing among stations depends on the variation of link qualities rather than the difference of data rates. The simulation results validate the accuracy of our analytical model. © 2008 IEEE. |
