Energy Efficient Secure Communication Model against Cooperative Eavesdropper

Applied Sciences, 2021
In a wiretap channel system model, the jammer node adopts the energy-harvesting signal as artificial noise (jamming signal) against the cooperative eavesdroppers.

Comment on "Relay Selection for Secure Cooperative Networks with Jamming" [PDF]

IEEE Transactions on Wireless Communications, 2012
It is the purpose of the note to point out that the Cumulative Distribution Function (CDF) (Eq. (23)) in Appendix A in the paper "Relay Selection for Secure Cooperative Networks with Jamming" by Krikidis et al. (IEEE Trans. Wireless Commun., vol. 8, no. 10, pp. 5003-5011, Oct. 2009) is not the exact expression but an approximation. We provide the exact

Secure Wireless Powered and Cooperative Jamming D2D Communications [PDF]

IEEE Transactions on Green Communications and Networking, 2018
This paper investigates a secure wireless-powered device-to-device (D2D) communication network in the presence of multiple eavesdroppers, where a hybrid base station (BS) in a cellular network not only provides power wirelessly for the D2D transmitter to guarantee power efficiency for the D2D network, but also serves as a cooperative jammer (CJ) to ...
