Cooperative Jamming with AF Relay in Power Monitoring and Communication Systems for Mining

Abstract

In underground mines, physical layer security (PLS) technology is a promising method for the effective and secure communication to monitor the mining process. Therefore, in this paper, we investigate the PLS of an amplify-and-forward relay-aided system in power monitoring and communication systems for mining, with the consideration of multiple eavesdroppers. Explicitly, we propose a PLS scheme of cooperative jamming and precoding for a full-duplex system considering imperfect channel state information. To maximize the secrecy rate of the communications, an effective block coordinate descent algorithm is used to design the precoding and jamming matrix at both the source and the relay. Furthermore, the effectiveness and convergence of the proposed scheme with high channel state information uncertainty have been proven.

Learning-Based IRS-Assisted Secure Transmission for Mine IoTs

“…However, these methods have limitations, such as extra power consumption for AN, computing resource requirements for PLA, and limited security guarantees for beamforming. For mining scenario, the authors in [ 15 ] investigate PLS in an underground mine environment using an amplify-and-forward relay-aided system with multiple eavesdroppers. The authors employ a block coordinate descent algorithm to design the precoding and jamming matrix at both the source and the relay, similar to other traditional PLS techniques, rather than during the propagation process.…”
