Dynamic spectrum sharing and cognitive radio networks were proposed to enhance the
Radio Frequency (RF) spectrum utilization. However, there are several challenges to realize …

To legitimately eavesdrop communications of suspicious users such as criminals, proactive
eavesdropping has been proposed as an effective approach. Current works considered that …

This paper considers the transmission of confidential messages over noisy wireless ad hoc
networks, where both background noise and interference from concurrent transmitters affect …

This paper studies the performance of short packet communications in the presence of
multiple eavesdroppers. We start our investigation by examining the fading wiretap channel …

Secure wireless communication has always been a hot research topic due to the
vulnerabilities associated with wireless channel. Physical layer aspects to secure wireless …

In the area of physical-layer security for wireless communications, jamming is one of the
methods that a malicious agent uses to actively attack legitimate nodes. The jammers make …

Wireless channels are increasingly being used to transmit highly sensitive information in the
Internet of Things. However, traditional cryptography methods cannot solve all security …

Wireless sensor networks (WSNs) play an important role in Cyber Physical Social Sensing
(CPSS) systems. An eavesdropping attack is one of the most serious threats to WSNs since …

We show that the problem of analyzing the outage probability (OP) in cellular systems
affected by cochannel interference (CCI) and background noise (BN) is mathematically …

In this paper, we investigate security issues in a collaborative wireless network in the
presence of eavesdropping attacks, where multiple amplify-and-forward (AF) relays are …
