Abstract :
In this paper, we propose a new throughput analysis for IEEE 802.11 distributed coordination function (DCF) considering the real channel conditions and capture effects under arbitrary load conditions employing basic access method. The aggregate throughput of a practical wireless local area (WLAN) strongly depends on the channel conditions. In real radio environment, the received signal power at the access point from a station is subjected to deterministic path loss, shadowing and fast multipath fading. We extend the multidimensional Markov chain model initially proposed by Bianchi to characterize the behavior of DCF in order to account both real channel conditions and capture effects, especially in a high interference radio environment.
