Enhancing wireless security via optimal cooperative jamming [PDF]
, 2012 In this work, we analyze the secrecy rate in a cooperative network, where a source node is assisted by relay nodes via cooperative jamming for delivering a secret message to the destination in the presence of an eavesdropper node.

Wireless secure enhancement with cooperative jamming
Tongxin xuebao, 2017 Secrecy capacity of intrinsically secure communication graph (iS-Graph) can be increased by reducing the signal quality of eavesdroppers with adding controlled interferences.The transmission of secret messages over wireless channels in which the ...

Cooperative Jamming Technique: Proposal, Survey and Future
Dianxin kexue, 2013 In the research of physical layer security, cooperative jamming is a special and novel research area. The artificial jamming signal is introduced into the wire-tap system to interfere the eavesdroppers and decrease their signal-to-interference-plus-noise

Cooperative jamming via spectrum leasing [PDF]
2011 International Symposium of Modeling and Optimization of Mobile, Ad Hoc, and Wireless Networks, 2011 Secure communication rates can be facilitated or enhanced via deployment of cooperative jammers in a multi-terminal environment. Such an approach typically assumes dedicated and/or altruistic jamming nodes, investing their resources for the good of the whole system.

Cooperative jamming for wireless physical layer security [PDF]
2009 IEEE/SP 15th Workshop on Statistical Signal Processing, 2009 Cooperative jamming is an approach that has been recently proposed for improving physical layer based security for wireless networks in the presence of an eavesdropper. While the source transmits its message to its destination, a relay node transmits a jamming signal to create interference at the eavesdropper.

Outage constrained secrecy rate maximization using cooperative jamming [PDF]
2012 IEEE Statistical Signal Processing Workshop (SSP), 2012 We consider a Gaussian MISO wiretap channel, where a multi-antenna source communicates with a single-antenna destination in the presence of a single-antenna eavesdropper. The communication is assisted by multi-antenna helpers that act as jammers to the eavesdropper.

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 ...

Cooperative Anti-Deception Jamming in a Distributed Multiple-Radar System under Registration Errors
Sensors, 2022 A distributed multiple-radar system has natural advantages in anti-deception jamming. However, most of the anti-jamming methods are proposed in full spatial registration. In practice, the registration error is difficult to eliminate, which will seriously
