Performance Modelling of IEEE 802.11g Wireless LAN

Abstract

Fairness of wireless channel access in terms of utilisation and throughput is studied for IEEE 802.11g by using the process algebra PEPA. Three models are presented to describe dif-ferent operating scenarios. Results are derived which demon-strate when and how unfairness might occur, leading to the penalisation of some nodes in a network.
