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 …

In this paper, we enhance physical layer security for downlink heterogeneous networks by
using friendly jammers and full-duplex users. The jammers are selected to transmit jamming …

Due to the inherent characteristics of system extensibility and implementation flexibility,
unmanned aerial vehicle (UAV)-assisted data aggregations will play an essential role in …

This paper proposes a new joint cooperative beamforming and jamming (JCBJ) scheme for
improving the physical layer security of decode-and-forward wireless networks where a …

This paper considers the secrecy communication of a wirelessly powered network, where an
energy-constrained legitimate transmitter (Alice) sends message to a legitimate receiver …

To understand the spatial deployment of base stations (BSs) is the first step to analyze the
performance of cellular networks and further design efficient networking protocols. Poisson …

In this paper, we investigate the physical layer security (PLS) of cooperative wireless-
powered networks where a source transmits confidential information to a destination with the …

This letter investigates the secrecy outage probability in the downlink with ordered user
equipment (UE) based on two ordering metrics. UEs and independently acting …

In this paper, we investigate secure communication over cellular uplinks in device-to-device
(D2D)-enabled cellular networks. We consider a more general scenario, in which multiple …

In this paper, we investigate wireless networks consisting of a legitimate transmitter (Alice), a
legitimate receiver (Bob), eavesdroppers (Eves), and friendly jammers. Two network …
