Survey on Energy Saving Methods for Green Communication Network

Abstract

In recent years telecommunication is playing a vital role in communication field. The power usage has become a major problem since the usage of wireless communication has increased, which has leaded to environmental impact in a drastic manner. The main goal of designing green base stations is for saving energy and reducing power consumption while guaranteeing service and coverage for users and ensuring the capability of base station for evolution. To reduce the energy consumed by base station sleep mode mechanism is adapted. For uplink and downlink communication a joint bandwidth and power allocation method is deployed which promotes energy saving for both network operators and mobile users. Thus, Green networking is to reduce the unnecessary energy consumption keeping environmental factors into consideration. This paper deals with the survey of the problems upon implementation of base station in cellular networks for heterogeneous communication and also compares the various work related to green networking.
