Heterogeneous networks using a mix of macrocells and small cells are foreseen as one of the solutions to meet the ever increasing mobile traffic demand. Nevertheless, a massive deployment of Small cell Access Points (SAPs) leads also to a considerable increase in energy consumption. Spurred by growing environmental awareness and the high price of energy, it is crucial to design energy efficient wireless systems for both macrocells and small cells. In this paper, the authors evaluate a distributed sleep-mode strategy for cognitive SAPs and they analyze the trade-off between traffic offloading from the macrocell and the energy consumption of the small cells.
