This paper evaluates the secrecy performance for the amplify‐and‐forward (AF) protocol
with partial relay selection (PRS) schemes in the scenario of multiple independent but not …

This paper investigates the secrecy outage probability (SOP) and intercept behavior for the
amplify‐and‐forward network over Nakagami‐m fading channels. Relay selection schemes …

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 …

In this paper, the security aspect of an amplify-and-forward relaying network with untrusted
relay nodes is considered. The untrusted nodes can help to forward the received signal and …

We evaluate the upper bound, lower bound and an approximate expression for secrecy
outage probability of a dual hop Amplify-and-forward (AF) relay system when the 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 consider an active eavesdropping scenario in a cooperative system
consisting of a source, a destination, and an active eavesdropper with multiple decode-and …

This paper considers secrecy of a three node cooperative wireless system in the presence of
a passive eavesdropper. The threshold-selection decode-and-forward relay is considered …

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

Cooperative communication in wireless relay systems can improve the physical layer
security, and the relay selection has great impacts on the security performances. In this …
