Abstract :
The femtocell concept is an emerging technology for deploying the next generation of the wireless networks, aiming at increasing capacity and offloading the overlay macrocell traffic. Energy costs account for as much as half of a mobile operator´s operating expenses. Thus, finding radio networking solutions that can greatly improve energy-efficiency as well as resource-efficiency (Green Communications) is not only benefit for the global environment but also makes commercial sense for telecommunication operators supporting sustainable and profitable business. In this paper, we propose a green and distributed algorithm to dynamically optimize the coverage of a femtocell group by adjusting their transmitting power in an Administrative Domain. The resulting evolved algorithm shows the ability to optimize the coverage well, and consequently the resultant substantial energy consumption.
