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 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 …

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

Physical-layer security (PLS) is examined in this paper for an underlay cognitive radio
network (CRN). Two secondary users (SUs) interact through a relay that is equipped with …

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

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 paper, we examine the physical (PHY) layer security in terms of secrecy outage of an
energy harvesting (EH) relay based underlay cognitive radio network (CRN) in the presence …

In this paper, the secrecy outage performance is studied for optimal relay selection (ORS)
schemes with energy harvesting system deployed at the secondary transmitter to improve …

In this paper, the secrecy outage probability (SOP) of an energy harvesting aided underlay
single input multiple output cognitive radio network under the multiple eavesdroppers is …

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 …
