PERFORMANCE ANALYSIS OF IEEE 802.11 NETWORKS

Abstract

The article consider a probabilistic models of 802.11 DCF WLANs based on the bidimensional Markov chains. We analyzed the variants of saturated and unsaturated load as well as conditions of frame transmitting. To increase the throughput and noise immunity of WLANs when significant noise intensity, it was proposed to use the fragmentation of data frames.
