We investigate the secrecy transmission of uplink non-orthogonal multiple access (NOMA)
with the aid of energy harvesting (EH) jammers. During each time frame, communication is …

We investigate physical layer security of an uplink NOMA system consisting of one base
station, multiple users and one eavesdropper. During each uplink transmission, two users …

Relay and friendly interference collaboration are effective technologies within the physical-
layer security (PLS) domain for countering eavesdroppers in wireless transmissions …

Internet of Things (IoT) is rapidly spreading and reaching a multitude of different domains,
since the fifth generation (5G) wireless technologies are the key enablers of many IoT …

This article investigates the physical layer security for a cooperative cognitive radio (CCR)
system with energy-harvesting (EH) technique, which consists of a cognitive source (CS) …

In this paper, we investigate the security and reliability trade-off (SRT) for a wireless sensor
network (WSN) which consists of one cluster head (CH), multiple users, and one …

This paper proposes a new scheme to enhance the secrecy performance of non-orthogonal
multiple access (NOMA)-based coordinated direct relay transmission (CDRT) systems with …

This paper focuses on wireless-powered communication systems, which are increasingly
relevant in the Internet of Things (IoT) due to their ability to extend the operational lifetime of …

This paper investigates the physical layer security for a distributed antenna system, where a
base station (BS) equipped with multiple distributed antennas transmits signals to a …

In this paper, we study the physical-layer security of a hybrid satellite-terrestrial network
composed of a satellite, multiple terrestrial decode-and-forward (DF) relays and users in the …
