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 …

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

We aim to improve both the energy harvesting efficiency and communication reliability of
overlay networks powered by harvested energy. To this end, multiple antennas are …

In this article, we investigate the performance of a piece-wise linear model of energy
harvesting-based multiuser overlay spectrum sharing system. Herein, an energy …

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 …

This paper studies an overlay network with non-orthogonal multiple access (NOMA) wherein
the far-licensed NOMA user is assisted by either the near-licensed NOMA user or the …

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

In this paper, the authors consider an underlay multi‐hop cognitive radio network with
energy harvesting secondary nodes, where there is a cluster of secondary decode‐and …

In this paper, the energy harvesting in a decode‐and‐forward (DF) relaying system with
beamforming and hardware impairments that is based on a realistic nonlinear model is …

Energy harvesting multihop networks allow for perpetual operation of low cost limited range
wireless devices. Compared with their battery-operated counterparts, the coupling of energy …
