Reducing power consumption of cellular networks by using various cell types and cell zooming

Nowadays, it is urgent to manage the power consumption in cellular networks due to the increased amounts of CO₂. As a result, this increased amount of CO₂ released leads to severe threats for global warming and to an increase in the energy cost in the base stations. This problem arouse as soon as the evolution of mobile networks emerged especially in the last decades. As a result, we have witnessed a massive growth in the number of base stations all over the world in order to serve these highly increasing demands on cellular traffic. Hence, mobile operators need to meet these new demands in wireless cellular networks, while they have to maintain reasonable costs to keep high benefits and maintain high quality of service at in addition to decreasing energy consumption. This is the concept of Green Communication. In our paper, we propose a new solution that will help in reducing energy consumption. The solution is a centralized algorithm applied in a heterogeneous Long Term Evolution (LTE) network using Macro and Micro base stations, applied with a new Control Server that will be implemented using a newly introduced server in evolved cellular networks.
