Optimal relay selection is investigated for secure cooperative communications against an
adaptive eavesdropper that can perform eavesdropping if the eavesdropping link has good …

This letter addresses the problem of secure communication in a cooperative network
operating in the presence of an eavesdropper as well as co-channel interference. Two …

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 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multiple decode-and-forward (DF) relaying with outdated relay selection.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 studies the cooperative transmission for securing a decode-and-forward (DF) two-
hop network where multiple cooperative nodes coexist with a potential eavesdropper. Under …

In this paper, we study opportunistic relay selection in cooperative networks with secrecy
constraints, where a number of eavesdropper nodes may overhear the source message. To …

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

In this paper, the impact of multiple active eavesdroppers on cooperative single carrier
systems with multiple relays and multiple destinations is examined. To achieve 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 …

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 …
