Abstract

This paper provides a simple and accurate analysis using Markov chain modeling to compute IEEE 802.11 DCF performance, in the presence of channel errors. We extend the analytical model of IEEE 802.11 DCF from Bianchi model to study throughput performance under noisy situation, where the node's transmit queue may be at times empty and then extension of his model to a nonsaturated environment and also we develop an expression for the nonsaturation throughput as a function of the number of stations, packet sizes, and raw channel error rates. The derived analysis, which takes into account packet retry limits, is validated by comparison with NS-2 simulation results. Numerical results and simulations are provided to validate the accuracy of our model and is verified by previous work.
