Recent studies indicate that Information and Communication Technology is responsible for a significant fraction of the world electricity consumption, ranging between 2% and 10%, with the twofold effect of contributing to global warming, through greenhouse gases release, and threatening sustainability of the growth of demand of Internet applications and services. For these reasons, energy efficient and sustainable networking, often simply referred to as Green Networking, has become a hot topic in the last few years. All aspects of Information and Communication Technology are under investigation, from energy saving design of individual devices, to strategies that consider the entire network's energy consumption in the design, planning, and management phases, to new paradigms for long term sustainability of the networks, that includes reformed attitudes of users' as well as smart energy harvesting techniques. The above considerations motivated us to promote this special issue on Green Networking. The specific purpose is to present innovative contributions to the research and development of energy efficient networking solutions and approaches for network sustainability.
