Energy efficient network planning: Issues and prospects in wired/wireless network

Abstract

Energy aware technologies in Information and communications technology (ICT) are becoming one of the most exigent research realms for the sustainable network industry since energy efficiency from silicon-technologies is not enough to overcome an energy consumption trend due to the increase of network traffic. This paper emphasizes a significance of greening ICT researches with rigorous forecasts for future energy consumption estimations in ICT industry. We review the concept of energy proportionality index ( EPI) as a major factor of energy-aware network planning. This paper also introduces fundamental research issues for green wired/wireless networks.
