摘要
为减少互相干扰的接入点数量,降低无线局域网中相邻接入点之间的同频干扰,在研究各类信道分配算法的基础上,以网络总干扰量最小为目标,设计了一种适用于集中式无线局域网的动态信道分配方案,提出了一个综合考虑邻居数目和接受功率的控制算法。结合实例,对算法进行了仿真分析,NS2仿真实验结果表明,该算法简单有效且可行,能够实现无线局域网中各接入点信道的动态调整,并起到良好的信道间负载均衡作用。
To reduce the number of inter-disturb access points and the interference among access points in same channel,with research on interference issus and channel assignment algorithms of wireless local area network,a scheme suitable for centralized wireless local area network was proposed aiming to minimize the total interference among access points,which compre hensively considerated the number of neighbor and the received power.And then the algorithm with cases was simulated and analysed,the result of NS2 simulation indicated that the algorithm was simple,effective and feasible,which could realise dynamic adjustment to the wireless LAN RF channel and had a better load balance effect among non-overlapping channels.
