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 …

Wireless networks are increasingly being employed to transfer highly sensitive information.
Due to the broadcast nature of wireless channels, security issues have been taken as a …

This paper deals with the use of jamming transmission for physical layer security in wireless
networks with power constraints. An approach that incorporates a dirty-paper coding (DPC) …

Cooperative jamming (CJ) can effectively improve the security of wireless communication
system in the physical layer, but such improvement is conditional on effective CJ …

A cooperative jamming system is investigated to enhance security of wireless
communications in the presence of eavesdroppers. Different from traditional wireless …

In this work, we investigate cooperative jamming schemes for the transmission of
