射频能量捕获网络信息与能量集成传输理论与方法

The nodes in Radio Frequency Energy Harvesting Network (RF-EHN) are able to harvest energy from radio frequency to support computing, communications, storage, etc. Currently, RF-EHN has become a hot topic in the research community. RF-EHN faces a serious challenge resulting from weak harvested energy, frequent sleeping, and often disconnection of communication link. This project investigates the theory and method on Integration of Information Transmission and Energy Transfer (IITET). The main contents include: (1) deployment of energy source and power supply mechanism that support high-effective energy harvesting, which enable the nodes to have longer runtime; (2) strategy of cooperation relaying IITET, which improves the efficiency of information transmission and energy transfer; (3) low-power, high-throughput, and reliable data delivery with IITET, which supports energy-efficient and effective data delivery and sharing; and (4) IITET oriented resource scheduling and optimization, which extremely takes advantage of network source and enhances network performance. This project is significant for the research and application of the Internet of Things in China.
