This paper applies the reinforcement learning in the joint relay selection and power
allocation in the secure cognitive radio (CR) relay network, where the data buffers and full …

In this paper, we investigate a Deep Reinforcement Learning based delay-constrained relay
selection for secure buffer aided Cognitive Relay Networks (CRNs). We model the relay …

In this paper, the physical layer security of underlay cognitive decode-and-forward (DF) relay
networks is investigated, wherein one secondary transmitter (ST) exchanges confidential …

In this paper, we investigate cooperative secure communications in a four-node cognitive
radio network where the secondary receiver is treated as a potential eavesdropper with …

In this, we propose a generalized partial relay selection (PRS) protocol to enhance the
secrecy performance for cooperative cognitive radio networks (CRNs) in terms of the …

In this study, the physical layer security for cognitive radio network (CRN) will be
investigated in which a secondary user transmitter (SU-Tx) sends confidential information to …

In this paper, we study the secrecy performance of a half-duplex cognitive relay network in
the presence of multiple eavesdroppers and multiple primary users. In particular, generic K …

Physical layer wireless communications are more and more essential, and are vulnerable to
malicious users owing to the nature of broadcast channels. Herein, we consider a …

This letter proposes several relay selection policies for secure communication in cognitive
decode-and-forward relay networks, where a pair of cognitive relays is opportunistically …

In this paper, we investigate beamforming design for cooperative secure transmission in
cognitive two-way relay networks, where the cognitive transmitter (CT) with multiple …
