- Energy efficiency is an important factor in cellular networks which is facing a major concern mainly because of environmental, economic and quality of service considerations, in addition making these networks “greener”. The main energy consumer in the cellular networks is Base Station; efforts have been made to reduce the energy consumption by dynamically switching off base stations and find ways to improve the energy efficient model for next generation cellular networks. In this survey we present the techniques related to energy efficient hardware components, cell switch on/off components, multiple input and multiple output management, deployment of heterogeneous networks and adoption of renewable energy sources. In addition, this paper discusses about each technique with various facts and figure which highlights the necessity of green communication with particular focus on techniques related to sleep mode in base stations and thereby offer clear insights to researchers about how to choose the best ways to reduce energy consumption in green cellular networks.
