Energy efficient Fi-Wi LAN with performance optimization

In the IEEE 802.11 standard meager effort has been invested towards devising greener WLAN communication. Especially with the massive deployment of Enterprise WLAN in indoor networks a lot of access points (APs) are densely packed for increasing the capacity offered. But most of the APs deployed are idle for a larger period of time in a day. This paper proposes to use a centralized controlled distributed antenna systems employing Radio over Fiber (RoF) techniques for efficiently managing energy resources in the network. The main contribution of the paper is that we propose power managed load balanced (PMLB) algorithm which minimizes the total power consumption of the overall network while appeasing the user demand and also provides load balancing across the APs for a better network performance.
