Joint Relay and Jammer Selection Improves the Physical Layer Security in the Face of CSI Feedback Delays

We enhance the physical layer security (PLS) of amplify-and-forward (AF) relaying networks with the aid of joint relay and jammer selection (JRJS), despite the deleterious effect of channel state information (CSI) feedback delays. Furthermore, we conceive a new outage-based characterization approach for the JRJS scheme. The traditional best relay selection (TBRS) is also considered as a benchmark....
