Artificial noise, energy harvesting, and overlay communications can assure design metrics of
modern wireless networks such as data security, energy efficiency, and spectrum utilization …

Abstract EHONs (Energy Harvesting Overlay Networks) satisfy stringent design
requirements such as high energy-and-spectrum utilization efficiencies. However, due to …

Energy scavenging overlay networks with artificial noise (ESONwAN) integrate three
emerging (energy harvesting, cognitive radio, physical layer security) technologies to boost …

In cognitive radio networks, direct communications between a primary sender–recipient pair
may be blocked due to uncertainties such as deep fading. Therefore, this paper studies …

In this paper, physical-layer security (PLS) of an underlay cognitive radio network (CRN)
operating over cascaded Rayleigh fading channels is examined. In this scenario, a …

The fifth-generation (5G) communications and beyond are expected to serve a huge number
of devices and services. However, due to the fixed spectrum allocation policies, the need for …

This paper investigates the physical-layer security (PLS) for an overlay cognitive radio
network (CRN). Due to the unreliability of direct communication between the primary users …

This work investigates the secrecy capability of energy harvesting based overlay cognitive
networks (EHOCNs). To this end, we assume that a message by a licensed transmitter is …

In this correspondence paper, we investigate the security and efficiency of data transmission
for overlay cognitive radio networks, which consist of a pair of primary users, multiple pairs of …

Physical-layer security (PLS) for an underlay cognitive radio network (CRN)-based
simultaneous wireless information and power transfer (SWIPT) over cascaded κ-µ fading …
