摘要

提出一种多速率802.11 WLAN中AP上时间公平的主动队列管理(TFRED)算法。TFRED算法依据各流的数据发送速率

为通过AP的单流设置不同的丢包概率

以保证各无线节点占用相等的无线信道时间。分析和仿真实验表明:TFRED算法能保护单流的吞吐率

在保证时间公平的同时

有效地提高了WLAN的总吞吐率。

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.
