Energy efficiency in future wireless broadband networks

Abstract

Over the past two decades wireless broadband networks have come to be considered the most convenient and reliable means of communications. This has led to an increased number of cellular base stations (BSs) deployed in both urban and rural areas. An increase in the number of BSs is directly proportional to an increase in energy consumption and carbon dioxide (CO2) emissions. To deal with these challenges, network operators and vendors are embarking on building energy efficient networks to support a greener economy and environment. In this research, we investigate the concept of green radio communications in wireless networks and discuss approaches for energy efficient solutions in wireless broadband network deployments. These solutions include: collaborative networking, cognitive radio (CR) technology, energy harvesting and television white spaces.
