A compendium of optimization techniques for green radio resource management

In recent past, along with other sectors, the telecommunication sector has grown enormously that have significant effects both on power expenditure and environmental hazards. Therefore, this paper presents the comprehensive overview about the energy efficiency and green communication. This paper summarizes the efforts that have been made in attaining green wireless communication in the perspective of radio resource management. The key interest in carrying this survey is to indicate those areas for the research that can be flourished more while attaining our goal of green wireless communication. In this article, basic concepts of energy-efficient communications are first introduced and then existing fundamental works and advanced techniques for energy efficiency are summarized, including information-theoretic analysis, OFDMA networks, MIMO techniques, relay transmission, and wireless resource allocation. Some of the important areas in energy-efficient design are also identified for future research.
