As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

One of the significant challenges that smart grid networks face is cyber-security. Several
studies have been conducted to highlight those security challenges. However, the majority …

The rapid development of the Unmanned Aerial Vehicle (UAV) brings much convenience to
our life. However, security and privacy problems caused by UAVs are gradually exposed …

In this paper, we study resource allocation for multiuser multiple-input-single-output
secondary communication systems with multiple system design objectives. We consider …

In this paper, we investigate secure device-to-device (D2D) communication in energy
harvesting large-scale cognitive cellular networks. The energy constrained D2D transmitter …

Abstract Industrial Internet-of-Things (IIoT) refers to the next stage in the evolution of
