Wireless Powered Communication Systems: Overview, Recent Results, and Challenges: Although wireless power transfer (WPT) has been first proposed by Nikola Tesla more than one hundred years ago, the application of this concept as a means to facilitate perpetual energy supply for wireless communication systems has emerged only recently. In fact, WPT and simultaneous wireless information and power transfer (SWIPT) are now seen by many as promising new technologies that may make the distributed nodes of short range wireless networks independent of external energy sources. In this talk, we will first discuss the benefits, limitations, and possible applications of WPT/SWIPT systems. In the main part of the talk, we will investigate the implications of WPT/SWIPT on the design of communication systems. In particular, we will discuss the impact of SWIPT on relay selection and secure communication. We will also study the performance of WPT systems with energy storage capability at the energy harvesting node. In the last part of the talk, we will elaborate on the challenges that have to be overcome to make WPT/SWIPT practical and suggest some topics for future research.
