The special session at the conference focused on "Electromagnetic Energy Transmission and Harvesting for IoT Applications," chaired by Dr Hao Zhang from Northwestern Polytechnical University, Dr Wenzhang Zhang and Dr Bintao Hu from Xi'an Jiaotong-Liverpool University (XJTLU). This topic concentrated on the energy supply issues for IoT devices, exploring the application prospects of electromagnetic energy transmission and harvesting technologies in the field of the Internet of Things.
特别会议亮点
物联网学院的博士生Medhav Kumar Goonjur提交的论文“Federated Learning-Empowered Resource Allocation Optimisation for E-Health IoT System”作为特邀论文在会议上进行了展示。该论文提出了一种创新的联邦学习资源分配优化框架，旨在为电子健康物联网系统提供更高效的资源管理策略。通过三级传输架构的优化，该研究在本地训练、无线传输和全局训练级别上实现了延迟和能耗的最小化，为电子健康物联网系统的发展提供了新的思路。
Medhav Kumar Goonjur, a Ph.D. student from the School of Internet of Things, presented his paper "Federated Learning-Empowered Resource Allocation Optimisation for E-Health IoT System" as an invited paper at the conference. The paper introduced an innovative federated learning resource allocation optimization framework aimed at providing more efficient resource management strategies for electronic health IoT systems. By optimizing the three-tier transmission architecture, the study achieved the minimization of latency and energy consumption at the local training, wireless transmission, and global training levels, offering new insights for the development of electronic health IoT systems.
物联网学院本科生祁妙的论文“Compact IoT Wireless Charging System with Impedance Matching Elimination”同样在会议上引起了广泛关注。祁妙同学设计了一种无需复杂阻抗匹配网络的双频段超表面结构天线，该天线能够在2.1 GHz和2.45 GHz两个频段上工作，且在这两个频段上均实现了超过60%的峰值RF-DC转换效率。这一设计不仅简化了无线充电系统的结构，还提高了系统的性能和经济性，为物联网设备的无线充电技术提供了新的可能性。
Another paper that garnered significant attention at the conference was "Compact IoT Wireless Charging System with Impedance Matching Elimination" by Miao Qi, an undergraduate student from the School of Internet of Things. Miao designed a dual-band metasurface structure antenna that operates without the need for a complex impedance matching network. The antenna is capable of exciting both the fundamental TM10 mode and the higher-order TM20 mode, operating at frequencies of 2.1 GHz and 2.45 GHz, respectively. Integrated with a rectifying circuit, the rectenna achieved peak RF-DC conversion efficiencies of 60.1% and 60% at 2.1 GHz and 2.45 GHz, respectively. The main contribution lies in exploring how metasurface antenna parameters affect the real and imaginary parts of impedance matching. This design not only simplifies the structure of the wireless charging system but also enhances its performance and cost-effectiveness, providing new possibilities for wireless charging technology in IoT devices.
