Queue Management Strategies to Improve TCP Fairness in IEEE 802.11 Wireless LANs

Tags:
wireless lan

Overview Wireless Local Area Networks (WLANs) based on the IEEE 802.11 technology have become increasingly popular and ubiquitous. The 802.11 standard allows each station in a WLAN equal opportunity to access the wireless channel, which can result in unfair sharing of network bandwidth between upstream and downstream TCP flows at an AP. This paper proposes two different queue management techniques to alleviate the unfairness problem, with one based on Selective Packet Marking (SPM), and the other based on Least Attained Service (LAS) scheduling. It evaluates these proposed solutions using the ns-2 network simulator.
