This paper studies the physical layer security in cognitive relay network (CRN) with multiple
antennas in the presence of multiple eavesdroppers. Under spectrum sharing scenario and …

This paper analyzes the physical layer security for cognitive relay networks under the peak
interference power constraint of the primary user receiver. In particular, a secondary user …

In this paper, we investigate physical layer security for multiple decode-and-forward (DF)
relaying underlay cognitive radio networks (CRNs) with fixed transmit power at the …

We study the secrecy outage performance of a dual-hop multiple relay decode-and-forward
(DF) cognitive relay network under the interference constraints in this paper, where all relays …

In this letter, we analyze the physical layer secrecy performance of a two-hop cooperative
cognitive underlay relay network with a decode and forward relay and a passive …

We study the physical-layer security of multi-hop secondary network under spectrum sharing
constraint caused by the primary, which consists of many simultaneously independent direct …

We study the multiple relay cognitive relay network under the interference constraints of
primary user in this paper, and the secrecy performance of the secondary network with the …

In this paper, we consider cognitive relay networks with N th best relay and beamforming
schemes under the joint impact of imperfect spectrum sensing and outdated channel …

In this paper, we propose and analyze an underlay cooperative cognitive network with
Physical Layer Security where a best relay is selected based on maximizing end-to-end …

In this paper, we investigate the secrecy outage performance of the decode-and-forward
cognitive relay network with the existence of the co-channel interference, where all nodes …
