Executive Summary

The IEEE 802.11 has become ubiquitous and gained widespread popularity as a protocol for wireless networks. As a result, various models have been proposed to analyze and model the parameters of interest. Since the seminal paper by Bianchi, throughput analysis of IEEE 802.11 DCF has come under much scrutiny. In the author evaluates the aggregate system throughput as a function of the number of nodes under saturation, i.e., each user has a packet to transmit at all times. The main feature of the analysis is the 2-dimensional Markov model, which captures the backoff phenomenon of IEEE 802.11, given an attempt rate for each node.
