Analyzing IEEE 802.11 DCF for FU-FB Systems under Multipath Fading Channels Using TUA

摘要

This paper presents the performance analysis of IEEE 802.11 DCF (distributed coordination function) using tagged user analysis (TUA). Performance of IEEE 802.11 DCF has been widely studied, mostly using Markov chains. Markov analysis becomes practically intractable for systems with finite users/stations (STAs) each having a finite buffer capacity. The analysis becomes even complicated under realistic channel models where multipath fading is encountered. This paper uses TUA, an approximate technique, for the analysis of quality of service (QoS) parameters like system throughput, wait delay, response time, packet blocking probability and average queue size. Simulation results show that TUA accurately predicts the performance of IEEE 802.11 DCF.
