Cooperative jamming and power allocation in three-phase two-way relaying wiretap systems
, 2013 The security of the three-phase two-way relaying system with an eavesdropper is investigated in this paper. A cooperative jamming and power allocation scheme is proposed to enhance the system secrecy capacity. When a source node transmits user signals to

Cooperative jamming in MIMO ad hoc networks [PDF]
, 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 ...

Cooperative radar jamming for groups of unmanned air vehicles [PDF]
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004 We consider a scenario where a group of unmanned air vehicles flies in a close formation and cooperates in their use of jamming resources to prevent being tracked by surface-to-air missile (SAM) tracking radars. We consider threats posed by a single or multiple SAM and investigate their impact on minimum-risk path planning.
