Optimization for the Deployment and Transmitting Power of AP Based on Green WLAN

Wireless local networks (WLANs) that contain a high-density of access points (APs) are being deployed rapidly all around the world, where large numbers of idle APs exist. In this paper, a optimization for the deployment and transmitting power of AP is proposed in order to save energy and reduce frequency interference. It includes green AP clustering where Fuzzy K-mean algorithm is used, AP´s second selection which is aimed to use fewer APs to guarantee the whole coverage, and AP´s transmitting power optimization which aims to save more energy and reduce frequency interference better. Then simulation is operated on a virtual WLAN of high-density. The simulation results shows that the optimization for the deployment and transmitting power of AP indeed can save much energy.
