Cooperative jamming for secure communications in MIMO Cooperative Cognitive Radio Networks
2015 IEEE International Conference on Communications (ICC), 2015Multiple-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 ...

Secure wireless communications via cooperative relaying and jamming
2011 IEEE GLOBECOM Workshops (GC Wkshps), 2011We consider secure wireless communications between a source and a destination aided by a multi-antenna relay, in the presence of an eavesdropper. In particular, two cooperation schemes of the relay are explored: cooperative relaying (CR) and cooperative jamming (CJ).

IIGA based algorithm for cooperative jamming resource allocation
2009 Asia Pacific Conference on Postgraduate Research in Microelectronics & Electronics (PrimeAsia), 2009This paper addresses a cooperative jamming resource allocation problem in electronic warfare and presents a resource allocation model of cooperative jamming (CJRA). Besides the capabilities and number of available jamming resources, the model also takes many constrains into account. Then an improved immune genetic algorithm (IIGA) is presented to solve

Friendly cooperation jamming for secrecy in LOS channel
2012 International Conference on Wireless Communications and Signal Processing (WCSP), 2012A multiple nodes wireless communication network in LOS channel is considered, consisting of a sender (Alice), a receiver (Bob), several friendly helpers, and a passive eavesdropper (Eve), each equipped with an omnidirectional antenna. The helpers work cooperatively to jam Eve.

Secure full-duplex relay network using cooperative jamming
2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017In this work, we propose a full-duplex relay (FDR) network for secure communication in the presence of an eavesdropper. We consider both the destination and the amplify-and-forward relay has a full-duplex capability for a higher rate and/or a stronger secrecy performance.

Relaying via Cooperative Jamming in Covert Wireless Communications
2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS), 2018In 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 ...

Improving Implantable Medical Device Security Through Cooperative Jamming
2023Implantable medical devices (IMDs) are medically necessary devices embedded in a human body that monitor chronic disorders or automatically deliver therapies, such as insulin pumps or pacemakers. Typically, they are small form-factor devices with limited battery and processing power.
