Cooperative Secure Transmission in the Presence of Untrusted Relay
International Journal of Distributed Sensor Networks, 2016 Considering a nonregenerative untrusted relay network, we investigate three different secure transmission strategies, for example, noncooperative strategy, conventional amplify-and-forward (AF) strategy, and cooperative jamming (CJ) strategy.
