Covert Communication With Relay Selection [PDF]

open access: yesIEEE 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,

Optimal Relay Selection Scheme with Multiantenna Power Beacon for Wireless-Powered Cooperation Communication Networks [PDF]

open access: yesSensors, 2020
Unlike the fixed power grid cooperative networks, which are mainly based on the reception reliability parameter while choosing the best relay, the wireless-powered cooperative communication network (WPCCN) and in addition to the reception reliability the

Relay Selection for Security Enhancement in Cognitive Relay Networks [PDF]

open access: yesIEEE Wireless Communications Letters, 2015
This letter proposes several relay selection policies for secure communication in cognitive decode-and-forward relay networks, where a pair of cognitive relays is opportunistically selected for security protection against eavesdropping. The first relay transmits the secrecy information to the destination, and the second relay, as a friendly jammer ...

On relay selection for decode-and-forward relaying [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2009
In this letter, we consider a multi-relay network operating in decode-and-forward mode. We propose a novel relay selection method with a low implementation complexity. Unlike the competing schemes, it requires neither error detection methods at relay nodes nor feedback information at the source.

Heterogeneous Relay Selection [PDF]

open access: yesIEEE 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.
