Paper Abstract

Performance anomaly is a serious problem that would affect the throughput in multirate IEEE 802.11 wireless networks. Existing performance anomaly solutions improve the throughput by adjusting one or more MAC parameters. However, they do not consider the frame delay. Thus the frame delay of some stations would be increased due to the MAC parameter adjustments. The increase of frame delay would seriously affect the quality of service (QoS) of multimedia applications such as video communications. In this paper we classify the existing solutions based on the MAC parameters to adjust, and analyze the effect of each type of solution on the frame delay. Numerical results show that the effects on frame delay significantly differ between the various types of solutions. This provides a novel perspective to evaluate the existing performance anomaly solutions.
