Paper Title
Green Communication and Energy Efficiency in 5G

Abstract
In this paper, we have studied various techniques and algorithms for Energy Efficient 5G networks which can lead towards power optimization and subsequently to green communication. The definition of energy efficiency is the number of bits that can be transferred over a unit of power consumption which is denoted by bits per joule. The power needed to transmit data is the major determining factor of energy efficiency in mobile devices. we should adopt the energy efficient architectures for the upcoming next generation networks to meet the increasing demand of quality of service, improved data rate and increased capacity and at the same time to be power efficient.
