Unmanned aerial vehicles (UAVs) have been undergoing fast development for providing
broader signal coverage and more extensive surveillance capabilities in military and civilian …

With increase in the use of social networks, we also need the increase in the security of
those networks. Making the connection secure is critical and the priority now a day so that …

Wireless communication environments comprise passive objects that cause performance
degradation and eavesdropping concerns due to anomalous scattering. This paper …

Abstract Unmanned Aerial Systems (UAS) have a wide variety of applications, and their
development in terms of capabilities is continuously evolving. Many missions performed by …

The goal of physical layer security (PLS) is to make use of the properties of the physical
layer—including the wireless communication medium and/or the transceiver hardware—to …

This paper investigates the maximal secret communication rate over a wiretap channel
subject to reliability and secrecy constraints at a given blocklength. New achievability and …

The Internet of Things (IoT) paradigm allows the connection and exchange of information
between millions of smart devices. This paradigm grows and develops exponentially as do …

Since the breakthrough of Shannon's seminal paper, researchers and engineers have
worked on codes and techniques that approach the fundamental limits of message …

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 …
