内容提要：
Energy harvesting (EH) is regarded as a promising technology to significantly extend the lifetime of battery-powered devices. Simultaneous wireless information and power transfer (SWIPT) is proposed to harvest part of the energy carried by the wireless communication signals and store it for future use. Currently, SWIPT has been successfully applied to energy-constrained relays that are mainly or exclusively powered by the energy harvested from the received signals. These relays are known as EH relays, which attract significant attention in both the academia and the industry. In this talk, we will first introduce the characteristics and performance of half-duplex and full-duplex EH relay networks. Then, we will discuss the power-splitting (PS) factor optimization in PS-based EH relay networks and present the impact of the residual self-interference at full-duplex EH relays. Furthermore, we will focus on the relay selection (RS) problem in EH relay networks. Both single relay selection (SRS) and general relay selection (GRS) without the limit on the number of cooperating relays are investigated and the corresponding RS methods are proposed. We will show that our proposed heuristic GRS methods outperform the SRS methods and achieve very similar performance compared with the optimal RS method achieved by exhaustive search but with dramatically reduced complexity.
