Energy saving techniques in next generation of mobile communication networks

Abstract

Generalized integration of new communication technologies expected to improve human`s life and bring the Sustainable Development Goals achievement closer in the next ten years. People will benefit from rapid exchange of information, high speed of data transfer, high-quality protection of uploaded and transmitted information, greater accessibility to medicine, the development of smart cities and homes, etc. But there are factors that significantly hinder the spread of fifth generation mobile networks. And the most critical of them is a high energy consumption that comes with rapid growing number of devices, machines and mobile subscribers. Most often, base stations always operate at full capacity, but there are statistics that show that the flow of base station clients is not always the same, so the energy consumption may be managed. It was found that cell zooming algorithms that mostly consider clients flow can save from 14 to 80% of the base station power consumption, however, not all studies pay attention to the quality of service. By balancing energy saving and quality of service, base station energy savings of about 15% can be achieved. In modern research, dynamic network scaling algorithms are more often presented and the location management investigation is identified as a solution that can help improve energy saving techniques and keep the quality of service on the optimal level.
