ABSTRACT
Energy use of base stations (BSs) in cellular networks has lately become a vital design consideration, due to increased awareness of environmental and economic issues for wireless network operators. This chapter introduces a range of techniques to reduce energy consumption in BSs, referred to as green cellular networks. In particular, the chapter focuses on presenting details on recent developments from analytical algorithms to practical applications regarding: (i) energy-aware heterogeneous deployment and (ii) joint BS on/off and user association problem. Further, the chapter presents several open problems and other directions including new paradigm and architecture towards green cellular networks.
