A survey on energy efficient 5G green network with a planned multi-tier architecture

The planned multi-tier energy efficient architecture of 5G Green network helps in achieving energy efficiency through various methods. The first method through which the objective of energy efficiency is achieved is by developing and planning the network according to the need of user at low power consumption. The other methods through which the energy of the architecture is efficiently utilized is by providing the hardware solutions by utilizing low power consumption components in the network, by harvesting the energy using wind and solar at multiple levels of the architecture, by Multi-beam carrier method, in which beam cover the area according to the presence of users in the range area of the base station, by cell Zooming, in which the energy efficiency is done by increasing the range of one base station to cover the end point users of other base station and to put the other station in sleep mode for saving the energy, when there is only end point users are present in that very cell. There are certain more methods such as Resource allocation, Spectrum Sharing, Internet of Things, Device to Device, Ultra-dense network and Massive MIMO through the energy of the 5G green network can be efficiently optimized.254
