Cooperative communication can improve the performance of communication system under
multi‐path fading conditions by relaying. If there is an eavesdropper in communication …

In this letter, a generalized multi-relay selection scheme is proposed to improve the security
in a cooperative relay network. Assuming that only the statistical channel state information of …

Physical layer security is a promising technique to realize secure wireless communications
without relying on conventional cryptographic methods. In cooperative networks with …

In this study, the authors evaluate secrecy performance of cooperative protocols with relay
selection methods under impact of co‐channel interference. In particular, the authors …

In this paper, we investigate the physical-layer security of cooperative communications
relying on multiple two-way relays using the decode-and-forward (DF) protocol in the …

This paper studies the problem of secure transmission in dual-hop cooperative networks
with untrusted relays, where each relay acts as both a potential helper and an …

This paper presents different relay and jammer selection schemes for one-way cooperative
networks to increase the security against malicious eavesdroppers. We consider a single …

For cooperative systems, in which an eavesdropper overhears source information through
relays' transmission, an optimal relay selection (ORS) scheme has recently been proposed …

In this paper, we present a comprehensive investigation on the secrecy performance of
opportunistic relay selection systems employing the decode-and-forward protocol over …

This paper is concerned with the relay and jammers selection in two-way cooperative
networks to improve their physical layer security. Three different categories of selection …
