无线局域网动态频道分配算法设计

Design of WLAN Channel Assignment Algorithm

无线网络已经成为布置局域网络的普遍选择,但在IEEE 802.11基础架构模式(Infrastructure mode)下,使用同一频道的相邻无线基地台可能会发生讯号相互干扰的情形。针对无线局域网讯号不稳定,容易受到各种干扰的问题,提出了能根据无线基地台的使用情况来动态调整工作频道,从而有效提升网络的整体效能的2个中央控制算法,并详细描述了算法的流程,实验结果显示,此方法能有效提升整体网络的效能。

With the rapid evolution of wireless technology,WLAN gradually becomes a common solution of setting up a local area network. While under the IEEE 802.11 infrastructure mode ,there may be interference between the nearby access points if they use the same channel. In this thesis ,we propose two centralized schemes to assign the channels of access points dynamically according to the AP utilizations and describe the process of the calculate way. The results show that this method can improve the efficiency of whole network.
