摘要: SUMMARY The fair allocation of the resources is an important issue in wireless local area network (WLAN) because all nodes compete for same radio channel. When uplink and downlink transmission congestion protocol (TCP) flows coexist WLAN, service biased toward TCP flows, tend to starve. In this article, we investigate special up/down unfairness problem point out that direct cause acknowledgement (ACK) packets occupy most buffer space access point. We thus propose a management algorithm ensure fairness among flows. order limit greedy behavior ACK packets, proposed adjusts maximum size allocated packets. Analysis simulation results show solution not only provides but also achieves 10–20% lower queue delay higher goodput than other solutions. Copyright © 2012 John Wiley & Sons, Ltd.
