无线局域网中负载均衡的AP主控式切换算法

AP-controlled handoff algorithm of load balance in WLAN

提出一种AP主控的切换式均衡算法,使用STA数目、RSSI和信道忙碌率等因素分配AP负载,并采用接入式算法思想,判断切换的目标AP是否接受超载AP的分流。该方法能正确衡量AP的负载,合理分流一部分超载AP的STA站点,有效地提高了系统的吞吐量。

This paper proposes an AP-controlled load balance algorithm based on the STA number, RSSI, and the channel busy ratio to allocate the AP＇s load. By adopting the idea of associate algorithm, the target of handoff AP can judge whether accept the distribute STA. The algorithm can judge the current AP＇s load correctly, distribute the STAs which associate with overload AP rationally, and improve the system throughput effectively.
