Energy-efficient mechanisms for next-generation green networks

Abstract

Explosion of new technologies and increasing digital dependency of users has led to revolutionary changes in wireless networking. With this, mobility, seamless communication, security, and better service quality have become the prime characteristics of new-generation networks (NGNs). However, achieving desired performance metrics and maintaining cost efficiency in power-constrained networking scenario is quite challenging which further degrade the end-user satisfaction. Apart from socioeconomic concern, ever-increasing power consumption is equally alarming from environmental perspective as well. This has called upon for the need of energy harvesting techniques to make NGNs greener. With the vision, the paper focused on power-constrained networking circumstances, limiting factors, and possible developments to enhance the energy usage in the forthcoming communication technologies.
