RIS-Assisted SWIPT for IoT Networks: A Survey of Architectures, Optimization, and Future Directions
The fusion of Simultaneous Wireless Information and Power Transfer (SWIPT) with Reconfigurable Intelligent Surfaces (RISs), i.e., RIS-aided SWIPT, is emerging as a promising paradigm for sustainable, energy-efficient, and intelligent sixth-generation (6G) Internet of Things (IoT) networks. By jointly enabling programma...
