Cooperative jamming for secrecy in decentralized wireless networks

2012 IEEE International Conference on Communications (ICC), 2012
Cooperative jamming as a physical layer security enhancement has recently drawn considerable attention. While most existing works focus on communication systems with a small number of nodes, we investigate the use of cooperative jamming for providing secrecy in large-scale decentralized networks consisting of randomly distributed legitimate users and ...

Cooperative jamming for secure communications in MIMO Cooperative Cognitive Radio Networks

2015 IEEE International Conference on Communications (ICC), 2015
Multiple-Input Multiple-Output Cooperative Cognitive Radio Networks (MIMO-CCRNs) have been proposed recently to further improve the spectrum efficiency. In MIMO-CCRNs, secondary users (SUs) equipped with multiple antennas can cooperatively relay the primary signals for the primary users (PUs) while concurrently accessing the same spectrum to send the ...

Safeguarding RSMA Networks With Cooperative Jamming and Relaying

IEEE Transactions on Vehicular Technology
Cooperative rate-splitting multiple access (C-RSMA) has emerged as a promising solution for increasing spectral efficiency over conventional RSMA. On the other hand, the presence of eavesdroppers seriously compromises secure communications due to the open nature of the wireless channel.

On cooperative jamming in wireless networks with eavesdroppers at arbitrary locations

2016 IEEE International Conference on Communications (ICC), 2016
This paper investigates cooperative jamming for secure connection in wireless networks. A cooperative jamming strategy is proposed to thwart eavesdroppers anywhere in the network, even if they are located close to the source or the destination.

Cooperative/distributed localization and characterization of GNSS jamming interference

2013 International Conference on Localization and GNSS (ICL-GNSS), 2013
Interference is the major threat to integrity of navigation systems. In this paper, we provide new approaches to localization and characterization operations of GNSS jamming signals in both cooperative and distributed architectures. As for localization, Differential Received Signal Strength (DRSS) and an Extended Kalman Filter (EKF) are exploited. With

Cooperative Jamming for Secure Communication With Finite Alphabet Inputs

IEEE Communications Letters, 2017
This letter considers cooperative jamming to secure communication in the presence of multiple eavesdroppers with finite alphabet inputs. Considering the global constraint, the joint design of artificial noise covariance matrices and power allocation between the source and the relays is studied.

Proactive Eavesdropping With Full-Duplex Relay and Cooperative Jamming

IEEE Transactions on Wireless Communications, 2018
In this paper, we consider a proactive eavesdropping scenario, where a central monitor tries to intercept the information exchanged between a pair of suspicious entities through amplify-and-forward full-duplex relays and a cooperative jammer. Specifically, the eavesdropping relays simultaneously listen to the suspicious transmitter and forward the ...

Relaying via Cooperative Jamming in Covert Wireless Communications

2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS), 2018
In this work, a covert communication scheme under block-fading channels is proposed where the relay, apart from forwarding source's information to the destination, also acts as a cooperative jammer. Stating precisely, the relay amplifies source's signal when required to relay the signal to the destination, otherwise it transmits artificial noise with ...
