With the rapid global deployment of Internet-of-Things Edge Devices (IEDs), Internet of Things (IoT) technology and IEDs are enriching and empowering our daily life with intelligence, efficiency and convenience. However, a tremendous number of IEDs, incurring a huge amount of energy consumption, are exacerbating the electric grid while there does not exist an appropriate approach to conveniently and stably power/charge these devices. Based on the existing research advances in the field, this project aims to leverage green energy to charge them in a far-field, highly efficient, human-safe and wireless fashion. The main research tasks include: 1) we will study and develop a new type of green energy harvesting device model to enable a base station (BS) to optimally schedule the usage of harvested green energy to wirelessly charge IEDs; 2) in order to improve the energy efficiency of far-field wireless charging, this project focuses on the following optimization issues, i.e., model design of IEDs, directional energy beam scheduling strategy, and energy beams phase-matching strategy for multi-energy BS joint charging; 3) we will study and develop the optimal multi-energy BS electromagnetic radiation control strategy and IED electromagnetic radiation feedback strategy to protect people from excessive radiation. The research outcomes are expected to help us achieve the green, efficient and convenient charging of IEDs, while ensuring the radiation safety for human beings in the wireless charging environments. This project presents a significant academic theoretical and application value in advancing the research and development of green IoT for our country.
