英文摘要： Due to the unique features of Electro-magnetic energy, wireless Rechargeable Internet of Things is expected to be a highly promising technology which is able to tackle the energy supply limitation, one the most critical hurdles, in the large-scale applications of Internet of Things. However, because of the temporal and spatial dynamics and differences, state estimation in wireless rechargeable internet of things has been one of the most challenging projects in the area of information technology. By considering the dynamics of wireless charging, communication as well as the plant, the project aims to improve the state estimation performance for the dynamic systems with wireless rechargeable internet of things. Based on both the theoretical analysis and experimental verification, the project first investigates the node localization in wireless rechargeable internet of things by moving the energy sources in a participatory manner which also establishes the temporal and spatial dynamic model of wireless charging. With the established models and obtained node location information, the project focuses on the transmission power control and routing energy optimization which largely improve the system state estimation performance. Based on graph theory, optimal estimation, convex optimization, and etc, this project establishes a complete set methods for codesign across the energy, communication and state estimation application layers for state estimation in wireless rechargeable internet of things. The theoretical results will also be evaluated through both simulations and mobile robots tracking testbed with wireless rechargeable internet of things.
