Abstract In Internet of Things (IoT) systems with security demands, there is often a need to
distribute sensitive information (such as encryption keys, digital signatures, or login …

We analyze a secure dual-hop mixed radio frequency-free space optical (RF-FSO) downlink
simultaneous wireless information and power transfer system. The FSO link and all RF links …

Internet of Things (IoT) is becoming an emerging paradigm to achieve ubiquitous
connectivity, via massive deployment of physical objects, such as sensors, controllers, and …

This paper studies the secrecy communication in an orthogonal frequency division
multiplexing system, where a source sends confidential information to a destination in the …

Wireless communication is one of the key technologies that actualize the Internet of Things
(IoT) concept into the real world. Understanding the security performance of wireless …

In this letter, we consider a multi-antenna downlink network where a secure user (SU)
coexists with a passive eavesdropper. There are two design requirements for such a …

This paper focuses on the secure transmission of wireless-powered full-duplex (FD) relay
systems, where a multiantenna source communicates with a single-antenna destination with …

In this article, a simultaneous wireless information and power transfer (SWIPT) system with
full-duplex (FD) Internet of Things (IoT) nodes is considered and investigated. We induce the …

In this work, we analyze the secrecy outage performance of a dual-hop relay system
composed of multiple-input-multiple-output radio-frequency (RF) links and a free-space …

In this paper, we investigate the power allocation of primary base station (PBS) and
cognitive base station (CBS) across different orthogonal frequency division multiplexing …
