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

摘要

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.
