Temporal fair active queue management algorithm for multi-rate 802.11 WLAN

Abstract

A temporal fair AQM-TFRED（temporal fair RED） on AP（access point） in multi-rate 802.11 WLAN was proposed.Taking into account the transmission rate of each flow,TFRED set different drop probability for each flow go-ing through the AP to guarantee equal channel usage time for each wireless node.Analysis and simulation results show that,compared with throughput fair AQM algorithms,TFRED achieves temporal fairness,per-flow throughput protection,and increase in total throughput.
