摘要
典型的切换延迟是由探测扫描、认证和重联接引起的,为了解决切换延迟和丢包率,文章总结了近几年来无线局域网(WLAN)的主要切换方法和切换策略,并给出了相应的解决方案和建议。综合考虑移动终端的信号强度、信道利用率以及接入用户数,并用层次分析法和切换概率法这两种方法对这些参数进行切换权值计算,选择出最适合的目标AP。
The typical handofflatency is caused by the probe scanning, authentication and reassociation, in order to solve the handover delay and lossing rate of package, the article summarizes the main switching method and strategy of wireless local area network(WLAN) in recent years, and gives the corresponding solutions and Suggestions .To comprehensively consider the signal strength of mobile terminals, channel utilization and access of users, with analytic hierarchy process (AHP) and the switch probability method, the two methods are used to calculate the handoffweights of parameters, and choose the most suitable target AP.
