Cooperative Jamming for Secure Communications in MIMO Relay Networks [PDF]
, 2011 Secure communications can be impeded by eavesdroppers in conventional relay systems. This paper proposes cooperative jamming strategies for two-hop relay networks where the eavesdropper can wiretap the relay channels in both hops.

Strongly Secure Communications Over the Two-Way Wiretap Channel [PDF]
, 2011 We consider the problem of secure communications over the two-way wiretap channel under a strong secrecy criterion. We improve existing results by developing an achievable region based on strategies that exploit both the interference at the eavesdropper ...

Cooperative Jamming in MIMO ad-hoc networks [PDF]
2009 Conference Record of the Forty-Third Asilomar Conference on Signals, Systems and Computers, 2009 In this work, we investigate cooperative jamming schemes for the transmission of confidential messages in ad-hoc networks. By letting mobile units (the helpers) in the vicinity of a legitimate receiver send out jamming signals while a transmitter communicates with the receiver, an environment that is hostile to any eavesdroppers can be established ...

Cooperative Awareness in Cognitive Wireless Networks for Jamming Control
2023 IEEE 9th World Forum on Internet of Things (WF-IoT), 2023 In cognitive wireless networks, opportunistic network devices can be programmed to take advantage of licence holders' idle times and dynamically adjust their operating parameters to improve transmissions. For this to be successful, these idle periods must be reliably detected.
