Energy Efficient Cellular Network Base Station: A Survey

Concept of Green communication is emerged from negative impact of wireless communication on the environment. Green communication through green networking can be implemented for making cellular network energy efficient. Green network system can be designed by using energy efficient networking approaches with minimum usage of radio resources. Observations from the recent studies suggest that a base station is the principal contributor of the energy consumption in cellular network. This paper presents a brief survey of different types of base stations and various methods to enhance the energy efficiency of a cellular network base station. Lastly, this paper is focusing on a brief introduction of power saving algorithms.
