IEEE Communications Magazine Feature Topic Issue on
"Green Communications" 
The unprecedented expansion of wireline and wireless networks has resulted in increase in energy consumption and left a significant environmental footprint. Recently, it has been reported that energy costs can account for as much as half of a mobile service provider’s annual operating expenses. If the aggregate energy consumption of networking devices would follow the growth trajectories of Internet traffic (i.e., about 60% per year), the environmental and financial consequences will be dire.Thus, making ICT equipment and applications “greener” can not only have a tangible positive impact on environment, but also help operators attain long-term profitability. Moreover, green communications can help the world reduce dependence on fossil fuel, enable demand response and distributed energy resources, and ultimately achieve sustainable prosperity. Accordingly, a myriad of communications and information technologies have already been exploited by the global smart grid initiatives to empower conventional power grid to support two-way energy and information flow.
To meet the green communications challenges, we have to resort to a plethora of paradigm-shifting technologies, including but not limiting to energy-efficient network architecture & protocols,energy-efficient wireless transmission techniques, energy-efficient home networking, energy-aware backbone networks,Smart Grid, and opportunistic spectrum sharing without causing harmful interference pollution (e.g., Green Spectrum).
This IEEECommunications Magazine special issue (feature topic issue) aims to provide a comprehensive overview of the state-of-the-art in technology, regulation and standardization for “Green Communications”, and present a holistic view of research challenges and opportunities in the coming green era. Suggested topics include but not limit to the following:
  • Energy-efficient circuit and device
  • Energy-efficient transmission switching and routing technologies
  • Energy-efficient base station architectures and networking
  • Energy-efficiency in wired and  wireless access networks
  • Energy-efficiency in home and enterprise networking
  • Energy efficiency of data centers and intelligent cloud computing
  • Protocols and protocol extensions to enable energy efficient networks  
  • Network-wide cross-layer optimizations to minimize energy consumption
  • Network load balance and smart information storage in distributed networks
  • Instrumentation for energy consumption measurement
  • Remote power management for wireless terminals and access networks 
  •  Hierarchical and distributed techniques for energy management 
  • Harvesting distributed energy generation
  • Smart Grid
  • Information theory on energy efficiency
  • Cognitive, cooperative and reconfigurable networks
  • Energy evaluation and comparison of different network technologies
  • Novel network concepts and architectures lowering the overall footprint of ICT (e.g., Compressed Sensing for network monitoring)
  • Realistic estimation of the worldwide footprint of communications and future evolution
  • Assessment of the footprint of individual communication devices, including life cycle assessment
  • Regulation and standardization
  • Deployment, trial experience, business models and applications (e.g., green multimedia broadcasting, femtocells)
