Due to the malicious attacks in wireless networks, physical layer security has attracted
increasing concerns from both academia and industry. The research on physical layer …

Internet of Things (IoT) is becoming an emerging paradigm to achieve ubiquitous
connectivity, via massive deployment of physical objects, such as sensors, controllers, and …

This correspondence studies a new secrecy beamforming (SBF) scheme for multiple-input
single-output non-orthogonal multiple access (MISO-NOMA) systems. In particular, the …

Unmanned aerial vehicle (UAV) wireless communication has recently been recognized to
be inevitable and prevalent in the fifth-generation (5G) wireless networks. In this paper, we …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same resource block to improve the spectral efficiency. Whereas due to the resource …

With the exponential increase of interconnected communicating devices which make up the
Internet of Things (IoT), securing the network transmission and the fifth generation (5G) …

This paper studies the secrecy rate maximization problem of a secure wireless
communication system in the presence of multiple eavesdroppers. The security of the …

This paper, for the first time, examines the impact of transmitter-side correlation on the
artificial-noise (AN)-aided secure transmission, based on which a new power allocation …

We study the cooperative secure transmissions in (multiple-input signal-output) MISO
vehicular relay networks where the infrastructure node with multiple antennas sends two …

We propose two cooperative secure transmission schemes to protect a two-hop buffer-aided
network assisted by an energy harvesting relay. In the first scheme, we assume that the …
