Security–reliability tradeoff analysis of untrusted energy harvesting relay networks
International Journal of Distributed Sensor Networks, 2018 We investigate secure communications in untrusted energy harvesting relay networks, where the amplify-and-forward relay is an energy constrained node powered by the received radio frequency signals, and try to unauthorizedly decode the confidential ...

Outage probability of selective decode and forward relaying with secrecy constraints
CoRR, 2011 We study the outage probability of opportunistic relay selection in decode-and-forward relaying with secrecy constraints. We derive the closed-form expression for the outage probability. Based on the analytical result, the asymptotic performance is then investigated. The accuracy of our performance analysis is verified by the simulation results.
