In this paper, we investigate the physical layer security performance of untrusted decode-
and-forward (DF) relay networks allowing intra-link errors with cooperative jamming …

In this letter, we investigate the potential benefits of adopting improper Gaussian signaling
(IGS) in a two-hop alternate relaying (AR) system. Given the known benefits of using IGS in …

We consider the problem of misbehavior detection in wireless networks. A commonly
adopted approach is to exploit the broadcast nature of the wireless medium, where nodes …

This paper introduces a simple combining technique for cooperative relay scheme which is
based on a Detect-and-Forward (DEF) relay protocol. Cooperative relay schemes have …

The performance of Selection cooperation in the presence of a malicious relay is analyzed.
The malicious relay introduces a new form of Denial of Service (DoS) attack at the physical …

This paper focuses on Byzantine attack detection for Gaussian two-hop one-way relay
network, where an amplify-and-forward relay may conduct Byzantine attacks by forwarding …

This paper investigates a disintegrated channel estimation technique required to accomplish
the spatial diversity supported by cooperative relays. The relaying strategy considered …

We apply the concept of artificial and controlled interference in a two-hop relay network with
an untrusted relay, aiming at enhancing the wireless communication secrecy between the …

This paper investigates pilot-aided channel estimation for two-way relay networks (TWRNs)
in the presence of synchronization errors between the two sources. The unpredictable …

In this paper, we analyze the impact of the detection error at the relay node to the
performance of the decode-and-forward cooperation system. We apply a simple detector …
