Abstract

This paper deals with the problem of performance degradation in wireless local area

networks (WLANs) based on IEEE 802.11n. When a wireless channel is shared by het-

erogeneous stations that have different data rates and packet sizes, each station occupies

a different amount of airtime because the basic channel access mechanism of WLAN was

originally designed to provide fair chance of channel access, regardless of packet size and

data rate. This leads to the degradation of overall network throughput and airtime fair-

ness among stations, which is known as performance anomaly. To resolve this problem,

we firstly formulate an optimization problem for a generalized two-level frame aggregation

whose objective is to maximize the achievable throughput under the constraint of airtime

fairness. Then, we propose a frame size adaptation scheme that controls the number of

packets in an aggregated frame. The proposed scheme is fully compatible with the IEEE

802.11 standard and works in a distributed manner, which neither modifies the channel ac-

cess mechanism nor resorts to a centralized scheduling algorithm. The extensive simulation

results confirm that the proposed scheme tightly regulates the airtime usage of each station

to be almost the same and significantly improves the overall network throughput compared

to other existing schemes.
