The usage of renewable energy has emerged as a promising solution for reducing the grid energy consumption of cellular networks. In this paper, we study the trade-off of users' satisfaction and grid energy consumption considering different types of traffic. Users' satisfaction of each type of traffic is represented by a utility function, as this allows for a better trade-off between energy consumption...
Powering cellular base stations with renewable energy are one of the long-term strategies for achieving green networks and reducing their operational costs. As an energy provider, the power grid is evolving into a smarter one, which allows more energy-efficient cellular networks and enables cooperation and interaction with the smart grid. On one hand, cellular networks can use harvested renewable...
Recently, renewable energy (RE) has been introduced as a promising solution to reduce the "non-green" energy consumption of cellular networks. In this paper, we study the electric bill reduction of a cellular network powered by both RE sources and the power grid in a variable electricity price environment. We decompose the problem of electric bill reduction into three sub-problems: RE allocation,...
In recent years a lot of research work was dedicated to energy efficiency in cellular networks. An emerging field of interest in that direction is the use of renewable energy sources such as wind and solar — a type of energy that is bound to increase and develop. In this paper we survey the existing works and present the fundamental principles and motivations necessary for a thorough understanding...
In this paper, we analyze energy-efficient cellular networks that are based on renewable energy. We focus on hybrid energy base stations that are powered by renewable energy and power grid. This will provide the opportunity of obtaining green communication and integrating the renewable energy in the existing infrastructure at the same time. We propose a classification of the research problems and...
