A survey on techniques related to base station sleeping in Green communication and CoMP analysis

TLDR: This survey discusses the analysis of coordinated multipoint transmission (CoMP) and its various parameters in BS switching and discusses about various techniques which implements BS switching for green cellular networking.

Abstract: Energy efficiency is an important factor in wireless networks which is facing a major concern mainly because of environmental, economic and quality of service considerations. Energy saving methods can be implemented with the adoption of renewable energy resources or by making hardware more energy efficient, but the major concern in these approaches are cost of purchasing, installing and transportation of equipment's can be an economical burden. So to improve energy efficiency various methods have been proposed and these methods can be referred as green cellular networking. These methods are far less costly, also implementations and testing becomes easy as it need not require any change in current network architecture. In this survey, we at first discuss about various facts and figure which highlights the necessity of green communication and we have discussed about various techniques which implements BS switching for green cellular networking. Generally based on the traffic pattern, some of the slightly loaded BS are switched off for reducing energy consumption. So at the end this review will discuss the analysis of coordinated multipoint transmission (CoMP) and its various parameters in BS switching.
