摘要

The integration of simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS) with thermal energy harvesting represents a cutting-edge advancement in wireless communication technologies. STAR-RIS is an innovative framework that enhances wireless network efficiency by simultaneously transmitting and reflecting signals, thus optimizing both coverage and capacity. This paper presents a review of STAR-RIS communications with thermal energy harvesting at the source, discussing its operational principles and potential impact on throughput efficiency and sustainability in wireless networks. By examining recent research and developments, we highlight the transformative potential of this technology in advancing green communication solutions and improving network performance. We also study underlay cognitive radio networks (CRNs) using STAR-RIS with power adaptation and thermal energy harvesting at the secondary source.
