Cooperative Jamming for Secure Communications in MIMO Relay Networks [PDF]

open access: yes, 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.

Cooperative Jamming in MIMO ad-hoc networks [PDF]

open access: yes2009 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

open access: yes2023 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.

Secure Degrees of Freedom for the MIMO Wire-tap Channel with a Multi-antenna Cooperative Jammer [PDF]

open access: yes, 2014
In this paper, a multiple antenna wire-tap channel in the presence of a multi-antenna cooperative jammer is studied. In particular, the secure degrees of freedom (s.d.o.f.) of this channel is established, with $N_t$ antennas at the transmitter, $N_r ...
