It has been pointed out in the past researches that per-flow unfairness in TCP throughput can be found in IEEE 802.11 wireless LAN environment. The main reason for the unfairness is that TCP keeps growing the congestion window size even when the access point is highly congested and numerous TCP ACK packets are discarded. In this report, we first propose a novel performance metric, considering both of per-flow fairness and bandwidth efficiency at network bottleneck. We then evaluate the performance of our proposed method for alleviating TCP unfairness problem through experiments in real wireless LAN environment using the metric. We show that the proposed method can improve TCP fairness up to 180 % regardless of vendor implementations of wireless access points and wireless interface cards. |
