Covert communication is crucial to ensure the safety of wireless communications in Internet
of Things (IoT) systems. In this article, a multiantenna relay is employed to enhance the …

In this work, we investigate a novel covert communication system, where the legitimate
transmitter attempts to communicate with a covert user in the presence of a warden and the …

Wireless connectivity in smart cities relies on widely deployed Internet of Things (IoT)
systems. However, the broadcast and open nature of wireless channels in such systems …

In this letter, a reconfigurable intelligent surface (RIS)-based passive covert communication
scheme is proposed, where source node Alice covertly transmits information to receiver Bob …

This article investigates the intelligent reflecting surface (IRS)-aided multi-antenna covert
communications. In particular, with the help of an IRS, a favorable communication …
