In this paper, we investigate the feasibility and performance of the covert communication
with a spectrum sharing relay in the finite blocklength regime. Specifically, the relay …

Covert communication is crucial to preventing the warder's detection of wireless
transmission. In general, small transmit power is required to satisfy the covertness …

This article investigates the covertness and secrecy of wireless communications in an
untrusted relay-assisted device-to-device (D2D) network consisting of a full-duplex base …

Device-to-device (D2D) communications underlaid cellular networks have emerged as a
promising network architecture to provide extended coverage and high data rate for various …

In this work, we investigate the status packet covert communication with time uncertainty in
time-critical wireless networks. We model the packet generation as a Poisson process that …

Covert communication, also known as communication with low probability of detection, aims
to provide reliable communication for legal users and prevent any other user from detecting …
