中文摘要: 在无线局域网的快速切换过程中，当存在多个可选的目标接入点(access point,AP)时，为了均衡负载，提出一种结合AP剩余带宽、信号强度以及AP当前负载比的目标AP选择方法。在所有可能的邻接AP中，若AP的剩余带宽小于移动终端所需带宽，则对这些AP不予考虑，否则，利用其邻接AP的负载比和终端接收到的AP的信号强度，计算函数，选择函数值最大的AP进行连接。仿真结果表明，该方法在整体性能上优于其它方法，没有出现某个AP负载超载。

Abstract:In fast handoff process of WLAN，this paper presents a method to choose goals for keeping the load balancing. The method combines the AP size of spare bandwidth, the signal intensity and the current load ratio of the AP. To all possible adjacency APs, if the AP free bandwidth is less than the bandwidth needed by the mobile terminal, the APs should not be considered. Otherwise, the function is calculated and the AP is chosen with the maximal function value to connect by using the load ratio of adjacency AP and RSSI of the terminal. Simulation results show that the method is better than other methods in the overall performance. They don’t present that a certain AP is overloaded.
