reen communications and computing (GCC) has been an active and will be a long lasting important field for technological research and development, although, in different stages, GCC may have different focuses and characteristics. In the near future, there will be three different, correlated, and important relevant directions and focuses: green Internet of Things (IoT) [1], green fifth generation (5G) wireless systems, and big data meeting green challenges [2]. The IoT refers to internetwork physical sensors, devices, and entities to enable collecting and exchanging data and signals. There are a number of concepts relevant to green IoT in different contexts, such as green cyber-physical systems, green machine-to-machine communications, and green device-to-device communications. GCC stands for a subset of global green efforts. As two leading global green efforts of the United Nations Environment Programme (UNEP), the 23rd Climate Change Conference (COP23) [3] and the third UN Environment Assembly (UNEA 3) [4] are being held in November and December 2017. COP23 will take place in Bonn, Germany, from 6 to 17 November this year [3]. Under the Presidency of the Republic of Fiji, delegates from 197 countries will negotiate the implementation of the Paris Agreement [5]. More than 20,000 delegates are expected to attend, and more than 830 organizations want to showcase their actions toward climate change [3]. The highest-level world decision-making body on the environment, UNEA 3, with the universal membership of all 193 UN Member States and the full involvement of UN organizations, specialized agencies, inter-governmental organizations, civil society, and the private sector, will be held in Nairobi, Kenya, from 4–6 December 2017 under the clear theme of pollution issues, which are expected to achieve a number of tangible commitments to terminate the pollution of our air, land, waterways, and oceans, and to safely manage our chemicals and waste [4]. All of the above efforts continue to inspire the IEEE Series on Green Communications and Computing Networks to support green efforts. The seventh, November 2017, issue of this Green Series includes relevant articles. There are two articles in this issue related to big data meeting green challenges. The article “Toward Big Data in Green City” first reviews the latest work concerning big data and sensor-cloud, respectively, and then introduces three

types of sensor-cloud for green city. The article “Big Data Analytics for Electric Vehicle Integration in Green Smart Cities” first makes a survey of the data analytics techniques for smart grid and EVs, and provides an overview of the data analytics landscape on the EV integration to green smart cities. There is one article related to wireless power transfer. “Simultaneous Wireless Information and Power Transfer: Technologies, Applications, and Research Challenges” surveys the current architectures and enabling technologies for SWIPT, and illustrates their importance. There are five articles related to advanced techniques in green wireless networks. The article “Green Heterogeneous Cloud Radio Access Networks: Potential Techniques, Performance Trade-offs, and Challenges” first proposes some potential techniques to energy-efficiently operate H-CRANs, and then elaborates on initial ideas of modeling three fundamental trade-offs. “Fully Exploiting Cloud Computing to Achieve a Green and Flexible C-RAN” reviews the recent advances of exploiting cloud computing to form a green and flexible C-RAN. The article “Enhancing Energy Efficiency via Cooperative MIMO in Wireless Sensor Networks: State of the Art and Future Research Directions” surveys several cooperative multiple-input multiple-output (CMIMO) models for different scenarios and discusses the implementations relevant to green communications. “Energy-Sustainable Traffic Steering for 5G Mobile Networks” proposes an energy-sustainable traffic steering framework to match energy distributions in both the spatial and temporal domains. The article “A Software-Defined Green Framework for Hybrid EV-Charging Networks” discusses how to jointly use these two types of charging methods whose advantages are complementary to each other, and then propose a software-defined green framework for hybrid EV-charging networks.
