Successive relaying secure transmission scheme based on inter-relay interference cancellation
Tongxin xuebao, 2017 A secure scheme based on inter-relay interference cancellation was proposed to solve untrusted relay eavesdropping problem in successive relaying systems.First inter-relay interference between trusted relay and untrusted relay was exploited as artificial

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.
