Covert Communication With Relay Selection [PDF]
IEEE Wireless Communications Letters, 2021 In this letter, we investigate covert communication in relay networks with relay selection. We consider the scenario that while forwarding the source’s message, the selected relay opportunistically transmits its own message to the destination covertly. We derive the probability of detection error (PDE) and the average covert rate (ACR) in a closed form,

Heterogeneous Relay Selection [PDF]
IEEE Transactions on Wireless Communications, 2013 Relay selection, a simple and efficient method of operating multi-relay networks, has in the past been considered only when all relays follow the same protocol. This work studies relay selection in heterogeneous relay networks where relays with different protocols can co-exist.
