Relay selection is considered to enhance the secrecy of a dual-hop regenerative multi-relay
system with an eavesdropper. Without assuming perfect decoding at the relays, the secrecy …

We have considered a dual‐hop wireless network consisting of a decode‐and‐forward (DF)
relay in presence of an eavesdropper. Relay can correctly decode and retransmit only if the …

The achievable secrecy rate of a dual-hop amplify-and-forward relaying system, in the
presence of an eavesdropper, is investigated based on the different values of the wireless …

This paper proposes relay selection to increase the physical layer security in multiuser
cooperative relay networks with multiple amplify-and-forward relays, in the presence of …

In this paper, we study the impact of correlated fading on the secrecy performance of
multiple decode-and-forward (DF) relaying with outdated relay selection. It is assumed that …

This paper investigates the physical-layer security of the modify-and-forward (MF) protocol in
multi-relay and multieavesdropper networks. Three relay selection critera are developed …

Physical layer security has recently attracted considerable attention in the context of
information‐theoretic point of view. In this paper, we investigate relay selection schemes for …

In this paper, we study a downlink multiuser network in which one base station sends its
message to one of multiple users, assisted by one of multiple intermediate decode-and …

In this paper, relay selection is considered to enhance security of a cooperative system with
multiple threshold-selection decode-and-forward (DF) relays. Threshold-selection DF relays …

In this study, secrecy outage performance is studied for partial relay selection (PRS)
schemes in cooperative systems over Rayleigh fading channels. In the considered systems …
