Joint Relay Selection and Power Allocation in Large-Scale MIMO Systems with Untrusted Relays and Passive Eavesdroppers
Ali Kuhestani, Abbas Mohammadi, Mohammadali Mohammadi
In this paper, a joint relay selection and power allocation (JRP) scheme is proposed to enhance the physical layer security of a cooperative network, where a multiple antennas sour…
Optimal Power Allocation by Imperfect Hardware Analysis in Untrusted Relaying Networks
Ali Kuhestani, Abbas Mohammadi, Kai-Kit Wong +3
By taking a variety of realistic hardware imperfections into consideration, we propose an optimal power allocation (OPA) strategy to maximize the instantaneous secrecy rate of a co…
Optimal Power Allocation and Secrecy Sum Rate in Two-Way Untrusted Relaying
Ali Kuhestani, Phee Lep Yeoh, Abbas Mohammadi
In this paper, we examine the secrecy performance of two-way relaying between a multiple antenna base station (BS) and a single antenna mobile user (MU) in the presence of a multip…
Secure two-way communication via a wireless powered untrusted relay and friendly jammer
Milad Tatar Mamaghani, Abbas Mohammadi, Phee Lep Yeoh +1
In this paper, we propose a self-dependent two-way secure communication where two sources exchange confidential messages via a wireless powered untrusted amplify-and-forward (AF) r…
Secure Two-Way Transmission via Wireless-Powered Untrusted Relay and External Jammer
Milad Tatar Mamaghani, Ali Kuhestani, Kai-Kit Wong
In this paper, we propose a two-way secure communication scheme where two transceivers exchange confidential messages via a wireless powered untrusted amplify-and-forward (AF) rela…
