In this article, we consider an energy-harvesting (EH) relay system consisting of a source, a
destination, and multiple EH decode-and-forward (DF) relays that can harvest the energy …

In this paper, a destination-assisted-jamming-based secure transmission is devised for an
untrusted and energy harvesting relay network. In the proposed scheme, both source and …

Relay assisted communication helps to extend the transmission coverage area. In more
realistic scenarios, the available relays are untrusted, which try to decode the confidential …

Limited power and computational resources make the employment of complex classical
encryption schemes unrealistic in resource-limited networks, eg, the Internet of Things (IoT) …

This letter studies the problem of secure communication for a dual-hop energy harvesting
(EH) relay network in the presence of multiple eavesdroppers. An adaptive cooperative …

In this paper, a joint beamforming alignment and suboptimal power allocation (Sub-OPA) for
a two-way untrusted relay network is presented. Considering the link between users is …

This paper considers a wireless-powered massive multi-input multioutput aided multiway
amplify-and-forward relay network, where a relay equipped with massive antennas charges …

The security performance in an amplify-and-forward dual-hop untrusted relay network is
considered. It is assumed that the source and multiple destinations are equipped with …

This paper studies the transmit antenna selection based on machine learning (ML) schemes
in untrusted relay networks. First, the exhaustive search antenna selection scheme is stated …

Security of confidential data at the physical layer has been analysed in a network where the
source sends the confidential data to the destination via multiple energy harvesting decode …
