Abstract—In this paper, we will first demonstrate the effects of unfairness performance of the IEEE 802.11 standard under a pre-computed routing scheme for two network configurations and a fixed traffic patterns. Firstly, we will examine the send rate, a quantity similar to the local throughput, for very simple chain and lattice networks with regular traffic patterns, and then we will investigate the performance of both types of fairness improvement schemes on this rate. The recently developed JEmu network simulator will be used for all simulations [1]. It is intended that the results will illustrate both the impacts of the traffic patterns on the performance of the link-level fairness models and will also highlight the better approach to guaranteeing fairness among subscribers..
