为了解决密集无线局域网(WLAN)中干扰严重、能耗高、网络性能难以优化等问题,提出了一种分布式接入点功率调整算法.终端周期性扫描获得备用接入点集合,并计算关联到备用接入点的功率等级信息.各接入点收集本地关联终端的上述信息,以降低发射功率为准则独立地计算终端的最优接入点.本算法能够在满足终端吞吐量需求的条件下,自适应地完成接入点功率调整和关联接入点的切换,降低WLAN在非高峰时段的整体能耗.
In order to solve the problems of serious interference, high energy consumption and difficult to optimize network performance in dense wireless local area network (WLAN), a distributed access point power adjustment algorithm is proposed. The terminal periodically scans to obtain a set of spare access points and calculates correlation To the backup access point power level information of each access point to collect the above information related to the local terminal to reduce the transmit power as the criterion to calculate the terminal optimal access point independently.This algorithm can meet the terminal throughput requirements of the conditions , Adaptively adjust the power of the access point and switch the associated access point, so as to reduce the overall energy consumption of the WLAN during off-peak hours.
