In this paper, we present a method of utilizing channel diversity to improve the secrecy
outage probability and the intercept probability in a cognitive radio (CR) network. With the …

This letter addresses the physical layer security for an underlay cognitive radio sensor
network over α-μ fading channels, where α and μ denote the nonlinearity and clustering of …

In this letter, we consider a single-input multiple-output cognitive wiretap system over
generalized-K channels, where the eavesdropper overhears the transmission from the …

This paper investigates the secrecy performance of an underlay cognitive radio network
(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …

This paper investigates the secrecy performance of an underlay cooperative cognitive
relaying network, wherein a secondary source vehicle communicates with a fixed secondary …

With fast growth of wireless services, secrecy has become an increasingly important issue
for wireless networks. In this paper, we investigate the secrecy capacity of the primary …

We consider a cognitive radio (CR) network with simultaneous wireless information and
power transfer (SWIPT) system having one base station (BS) with multiple antennas that acts …
