Special Issue Information

Dear Colleagues,

Over the last decade, interest in energy harvesting has increased due to its environmental friendliness and ability to power appliances without power supplies and electrical wires; extend the battery lifetimes (or eliminate them altogether); reduce maintenance costs; and, especially, reduce the need to replace batteries in sensors that are impossible to reach. With advances in energy-harvesting techniques, it is now feasible to build sustainable sensor networks to support long-term applications. Unlike battery-powered sensor networks, the goal of sustainable sensor networks is to utilize a continuous stream of ambient energy effectively. Instead of pushing the limits of energy conservation, we aim to design energy-synchronized communication and computing schemes that keep energy supplies and demands in balance for future sustainable IT. The Industrial Internet of Things (IIoT) is an emerging computing concept that describes a structure in which physical objects, each provided with unique identifiers, are always connected to the Internet without requiring human interaction. Long-term and self-sustainable operation are key components for the realization of such a complex network and entail energy-aware devices that are potentially capable of harvesting their required energy from ambient sources. Among different energy harvesting methods, such as vibration, light, and thermal energy extraction, Wireless Energy Harvesting (WEH) has proven to be one of the most promising solutions for sustainable IT by virtue of its simplicity, ease of implementation, and availability. This Special Issue focuses on cutting-edge research that develops an effective communication and computing methodology for Sustainable IT. This Special Issue addresses the topic of energy harvesting communication and computing for sustainable IT in its different aspects and invites publications on the following topics:

  • Energy-harvesting base-station
  • Energy-harvesting and energy-efficient IoT
  • Low-power and energy-harvesting wireless sensor network
  • Light (solar), thermal, vibration, RF, motion, wind energy harvesting
  • Energy harvesting, storage, and recycling
  • Sustainable architectures for smart grids
  • Optimization techniques for efficient energy consumption
  • Smart control for eco-friendly buildings and systems
  • Sustainable real-time systems
  • Sustainable computing, communication
  • Security and safety for Sustainable IT
  • Green and cloud computing
  • Sustainable energy generation, transmission, distribution and delivery

A method to secure the generator reactive power reserve by adjusting the transformer tap to improve the power system penetration of renewable energy has been proposed in this study. The tap is adjusted based on the voltage and reactive power sensitivity in the power system network. That is, the transformer tap sensitivity is calculated and analyzed to adjust the tap variation to gain sufficient or the least necessary amount of reactive power reserve. This method can be effective for generators without any margins in the reserves. The optimization problem based on the calculated sensitivities and effectiveness are presented. The optimum solution derived from such a problem provides the minimum control amount necessary to maintain the system voltage and dynamic reactive power reserve at their pre-specified levels to improve the power system acceptability of renewable energy. To demonstrate the effectiveness of the method proposed, a simulation has been performed for an IEEE-25 bus system. The results from simulations prove that the voltage has been well maintained while securing a dynamic reactive power reserve through optimal control based on the sensitivity analysis. Full article

Currently, the exchange cycles of various computers, smartphones, tablets, and others have become shorter, because new high-performance devices continue to roll out rapidly. However, existing legacy devices are not old-fashioned or obsolete to use. From the perspective of sustainable information technology (IT), energy-efficient virtualization can apply a way to increase reusability for special customized devices and enhance the security of existing legacy devices. It means that the virtualization can customize a specially designed purpose using the guest domain from obsolete devices. Thus, this could be a computing scheme that keeps energy supplies and demands in balance for future sustainable IT. Moreover, energy-efficient virtualization can be the long-term and self-sustainable solution such as cloud computing, big data and so forth. By separating the domain of the host device based on virtualization, the guest OS on the segmented domain can be used as a Trusted Execution Environment to perform security features. In this paper, we introduce a secure platform to protect sensitive user data by domain isolation utilizing virtualization. The sensitive user data on our secure platform can protect against the infringement of personal information by malicious attacks. This study is an effective solution in terms of sustainability by recycling them for special purposes or enhancing the security of existing devices. Full article
