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 …

This study deals with opportunistic relay selection in cooperative networks with secrecy
constraints, where an eavesdropper node tries to overhead the source message. Previously …

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 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 …

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 …

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 …

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 …

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multiple decode-and-forward (DF) relaying with outdated relay selection.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 …

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

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