Increasing the number of deployed base stations of different range and capabilities creating ultra dense networks is one of the solutions that will be adapted in order to cover the demand. Energy efficiency schemes are needed in order to keep the energy impact of such an approach limited. In this paper we focus on densely deployed femtocells (clusters) evaluating the power savings resulted from a power controlled sleep mode mechanism. The mechanism tries to reduce the number of operating closed access femtocells, by providing perfofmance incentives to the clusters subscribers to coordinate reducing energy consumption without compromising their throughput. Simulations investigate the different levels of power savings depending on the chosen configuration
and the deployment density.1 aBouras, Christos1 aDiles, Georgios1 aMoulias, Theodoros  uhttp://telematics.upatras.gr/telematics/publications/energy-savings-power-control-fro-5g-dense-femtocells
