WL AN中基于查表法的接入式负载均衡技术研究

摘要

WLAN has developed rapidly with more and more airports, railway stations, coffee shops, hotels and other public places deployed WLAN. But there is a load imbalance between APs in WLAN, which greatly reduces the network performance and seriously affects the user's experience. The lfow of people in public places is usually cyclical, For this reason, this paper presents an access-type load balancing method which is based on table-lookingup method in WLAN. And some simulation experiments were done with this method. According to the simulation results, we can see that the method can achieve satisfactory effect of load balancing.%越来越多的机场、车站、咖啡厅、宾馆等公共产所都部署了WLAN，WLAN得到了迅猛发展，但WLAN中AP之间负载的不均衡，大大降低了网络的整体性能，严重影响了用户体验。公共场所的人流量一般都是周期性的，基于这个周期性的特点，文章提出了基于查表法的接入式负载均衡方法，并对该方法进行了实验仿真。分析仿真结果可知，本方法可以达到令人满意的负载均衡效果。
