Special Issue on “Energy‐efficient Networking” INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS (Indexed by SCIE ‐ 2013 Impact Factor: 1.106) Editor‐in‐Chief: Mohammad S. Obaidat ISSN: 1074‐5351

Fueled by the increasing popularity of the Internet and evermore bandwidth-hungry services, networking technologies constitute one of the most fast growing areas in the field of the IT industry. This fast growth has led to a point where the energy expenditure of networking infrastructure constitutes a significant portion of the total energy expenditure and moreover, the trend is towards an additional increase. Thus, the development of energy efficient networking technologies for the various segments (backbone and access parts) of today’s Internet has recently emerged as a significant research area. The primary focus of such green technologies, is towards reduction of the energy footprint of the networking infrastructure, thus enabling sustainable development, low operational costs and environmental safety. The objective of this special issue is to report state-of-the art results in energy-efficient networking protocols by welcoming contributions originating from both academic and industrial research. These should be original contributions solicited in relevant areas of energy-efficient networking protocols.
