Cooperative communication utilizes node cooperation for enhancing the diversity gains
during secure communication against eavesdropping and jamming which are the common …

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

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

In practice, full-duplex (FD) transmission achieves better system outage performance than
that of half-duplex (HD) transmission but suffers from strong self-interference (SI). In this …

The increasing use of network-connected devices places a higher risk on security and
privacy of data. The characteristics of the wireless channel can be employed to provide …

In this paper, we investigate the secrecy performance of dual-hop decode-and-forward
cognitive relay networks taking into account the channel correlation between the main and …

In the spectrum sharing mode, the transmitting power of the secondary user (SU) is optimally
controlled, such that no additional interference occurs at the primary user (PU). In this paper …

In cooperative cognitive radio networks (CCRNs), there has been growing demand of
transmitting secondary user (SU) source information secretly to the corresponding SU …

An unlicensed relay is located between an unlicensed sender and an unlicensed recipient
for securing the sender's message against a wire-tapper in underlay cognitive networks …
