This letter presents a new method for analyzing nonsaturated IEEE 802.11 DCF networks: the behavior of each station in a WLAN is modeled as a Markov renewal process, and the throughput expression is derived from the traffic conservation principle for queueing systems in equilibrium. The Markov renewal process model simplifies the derivation of the closed form solution for the probability that each...
In order to improve the accuracy of analysis, we propose a improved bidimensional Markov chains model for estimating the performance of IEEE802.11 DCF for non-saturated conditions taking into account the impact of channel errors in a non-ideal channel in this paper and then, using the improved model, analyzes the performances of IEEE802.11 DCF Wireless LANs for different channel bit error rate, deriving...
