uring the period from 23 May to 28 May 2016, the second United Nations Environment Assembly (UNEA-2) was held in Nairobi, Kenya, and was attended by over 2500 delegates from 174 countries, including 123 ministerial-level participants as well as 230 representatives of business and 400 representatives from accredited major groups and stakeholders [1]. With the theme of delivering on the environmental dimension of the 2030 Agenda for Sustainable Development, UNEA-2 concluded with a high level of agreement among environment ministers of the world on the need to strengthen the environmental dimension in the process of implementing the sustainable development goals (SDGs), although there were no concrete proposals agreed on how UNEP can ensure that the environmental dimension is included at the heart of all development policies. The first session of UNEA in June 2014 discussed major issues such as illegal trade in wildlife, air quality, environmental rule of law, financing the green economy, and the SDGs. The establishment of UNEA shows that the environment has recently moved from the margins to the center of the sustainable development agenda of the world. UNEA-2 adopted 24 resolutions addressing diverse topics, such as sustainable consumption and production, biodiversity, illegal wildlife trade, desertification, and marine issues [1]. The scope of the IEEE Technical Committee on Green Communications and Computing (TCGCC) has included environmental sustainability topics since it was the IEEE Technical Sub-Committee on Green Communications and Computing (TSCGCC) in 2011 [2]. In two recent papers published in May 2016, the relevance of environmental sustainability to information and communication technologies has been addressed specifically [3, 4]. This Green Series would like to call for more high-quality submissions addressing more general environmental issues. The fifth, November 2016, issue of the IEEE Series on Green Communications and Computing Networks includes nine articles relevant to green ICT. The article “Green Touchable Nanorobotic Sensor Networks” explores a broader aspect of green communications for nano-robots. The article describes how these robots may

be useful in a wide range of applications, particularly for monitoring the human body and detecting illness. The article “Simultaneous Information and Energy Flow for IoT Relay Systems with Crowd Harvesting” addresses energy-efficient sensor networks for the Internet of Things. The article “LIFETEL: Managing the Energy-Lifetime Trade-off in Telecommunication Networks” discusses the important issue of device lifetime. The article “Dynamic Energy Trading for Wireless Powered Communication Networks” introduces a dynamic energy trading mechanism to improve the energy supply reliability and performance of wireless powered communication networks. The article “Power-Saving Methods for Internet of Things over Converged Fiber-Wireless Access Networks” takes advantage of converged fiber-wireless access networks to design a shared communication infrastructure for supporting both IoT applications and traditional services. The article “Sustainability Information Model for Energy Efficiency Policies” models energy efficiency policies extending the Internet Engineering Task Force (IETF) Policy Core Information Model. The article “Software Defined Networking, Caching, and Computing for Green Wireless Networks” develops a software-defined networking-caching-computing integrated architecture for next generation green wireless networks. The following two articles were independently handled through the Open Call by the Associate Editors-in-Chief, Zoran Zvonar. The article “Green Data Path for TCAM-Based Software-Defined Networks” proposes a green architecture for SDN networks using the dynamic voltage and frequency scaling (DVFS) technique. The DVFS-enabled controller and switch can generate the frequency and voltage configurations according to a certain energy efficiency policy for TCAM chips. The article “Toward the Development of a Techno-Social Smart Grid” proposes a new techno-social framework for smart grids. Knowing that the social aspects, interactions, and behavior of people and their energy usage/demands are intertwined these days, new forms of collecting qualitative information is becoming important.

RangaRao Venkatesha Prasad [SM] ([email protected]) received his Ph.D. from the Indian Institute of Science, Bangalore. During his Ph.D. research, a scalable VoIP conferencing platform was designed. Many new ideas including a conjecture were formulated and tested by developing an application suite based on the research findings. Part of the thesis led to a startup venture, Esqube Communication Solutions. In 2005, he joined the Technical University of Delft (TUDelft). He has worked on personal networks (PNs), IoT, CPS, and energy harvesting networks. His work at TUDelft has resulted in 180+ publications. He is a Senior Member of ACM.
