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 ...

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,

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.

Data-Driven-Based Relay Selection and Cooperative Beamforming for Non-Regenerative Multi-Antenna Relay Networks

open access: yesIEEE Access, 2021
In this paper, an attempt to exploit the benefits of data-driven methods in solving joint relay selection and beamforming for non-regenerative relay networks has been made.

Secure 5G Wireless Communications: A Joint Relay Selection and Wireless Power Transfer Approach

open access: yesIEEE Access, 2016
In this paper, we investigate the secrecy performance of an energy harvesting relay system, where a legitimate source communicates with a legitimate destination via the assistance of multiple trusted relays.

Incremental Relaying with Partial Relay Selection

open access: yesIEICE Transactions on Communications, 2010
We propose an incremental relaying protocol in conjunction with partial relay selection with the aim of making efficient use of the degrees of freedom of the channels as well as improving the performance of dual hop relaying with partial relay selection (DRPRS).

Power Consumption Scheme Oriented to Full-duplex Multi-relay Cooperative SWIPT Networks [PDF]

open access: yesJisuanji kexue, 2022
In full-duplex multi-relay cooperative simultaneous wireless information and power transfer (SWIPT) networks,traditional relay selection algorithms have not taken into account the idle utilization of unselected relays.As a result,the performance waste of
