Comments on IEEE 802.11 saturation throughput analysis with freezing of backoff counters

Abstract

This letter presents an accurate model for the performance analysis of the IEEE 802.11 saturation throughput with freezing of the backoff counter. The model corrects the existing model presented by Ziouva and Antonakopoulos which assumes that the channel access probability and station collision probability are independent of channel status. Simulation results show the accuracy of the new model. © 2005 IEEE.
