Abstract

In this study, we propose ARF-aware TCP that resolves the performance anomaly in 802.11 WLAN networks. Performance anomaly is a network symptom that fairness among the nodes is broken when multiple nodes in the same channel have different link rates. Recent studies on the performance anomaly focus on QoS mechanism at MAC layer. However, MAC layer approach has drawbacks such as framing overhead or side-effects at transport protocol. ARF-aware TCP successfully provides a fair-share of wireless links in an easier way. By adjusting the congestion window size during a RTT period, we can get high fairness and enhanced throughput. The fairness index in our cases increases from 0.63, 0.74 to 0.99, 0.99 respectively. In addition, it improves the performance of sessions up to 30% by resolving the performance anomaly.
