Cooperative Covert Communication With Transceiver Hardware Impairments
IEEE Open Journal of the Communications SocietyThis study investigates covert communication in the presence of a half-duplex amplify-and-forward (AF) relay, while accounting for transceiver hardware impairments. A cooperative jamming strategy and channel uncertainty are employed to achieve covertness.

A novel secure relay selection strategy for energy-harvesting-enabled Internet of things
EURASIP Journal on Wireless Communications and Networking, 2018 In this article, we focus on the problem of relay selection for the cooperative cognitive radio-based Internet of things. In such systems, a pair of primary user devices (PUs) can only communicate with each other through a relay.

International Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.Exploiting privacy‐aware user task offloading in a multi‐UAV–assisted edge computing system offers a new approach to reduce and balance energy consumption and latency. However, the complexity and variability of operating scenarios can make privacy‐aware user task offloading strategies challenging. This paper examines a system with multiple ground users,

Software: Practice and Experience, Volume 55, Issue 11, Page 1749-1772, November 2025.ABSTRACT Introduction The popularization of blockchain‐based applications made evident a critical challenge, namely the inherent isolation of these decentralized systems, akin to the disconnected and technologically diverse local area networks of the 1970s. This lack of interoperability limits the potential for widespread adoption and innovation in the
