In this paper, we study the role of cooperative relays to provide and improve secure
communication rates through decode-and-forward (DF) strategies in a full-duplex multiple …

In this paper, we provide a comprehensive study of secrecy transmission in decode-and-
forward (DF) relay networks subjected to slow fading. With only channel distribution …

In this paper, we consider a cooperative relay network consisting of a source, a destination
and multiple decode‐and‐forward relays in the presence of multiple eavesdroppers, which …

This paper studies the effect of outdated channel state information on relay selection for a
secure amplify‐and‐forward relay network. In the considered system, one of the multiple …

For full-duplex (FD) relay networks, secure communication is an important issue. In this
letter, considering decode-and-forward scheme, we investigate the optimal power allocation …

This letter considers improving end-to-end secrecy capacity of a multihop decode-and-
forward relaying system. First, a secrecy rate maximization problem without transmitting …

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 …

Physical layer security offers an efficient means to decrease the risk of confidential
information leakage through wiretap links. In this paper, we address the physical-layer …

This paper quantifies the impact of correlated fading on secure communication of multiple
amplify-and-forward (AF) relaying networks. In such a network, the base station (BS) is …

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 …
