In overlay networks, the cognitive sender (CS) assists the primary transmitter (PT) by
broadcasting the superposed signal composed of both cognitive and primary information …

This paper investigates a nonlinear energy scavenging overlay network (NLESON) wherein
a primary source (PS) communicates with a primary destination (PD) probably under aid of a …

Improper Gaussian signaling (IGS) scheme has been recently shown to provide
performance improvements in interference-limited networks as opposed to the conventional …

Cognitive radio networks (CRNs) are acknowledged for their ability to tackle the issue of
spectrum under-utilization. In the realm of CRNs, this paper investigates the energy …

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 …

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 …

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

In this paper, we propose an energy harvesting-based spectrum access model in overlay
cognitive radio (CR). In the proposed scheme, one of potential secondary transmitters (STs) …

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

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 …
