This paper investigates cooperative jamming for secure connection in wireless networks. A
cooperative jamming strategy is proposed to thwart eavesdroppers anywhere in the network …

This paper explores cooperative jamming for security in wireless networks. No location data
of eavesdropper is available, meanwhile no constraint on the figures of eavesdroppers is …

Security has always played a critical role in wireless cooperative communication systems
design. Eavesdropping and jamming are two common threats to the information security in …

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 …

Two-hop relay wireless network serves as an important network model for the performance
study of general wireless networks, while cooperative jamming has been a promising …

The wireless transmission environment opens up opportunities for an eavesdropper to
intercept a secret message from the source to the legitimate destination, particularly in the …

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

A 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 …

Cooperative jamming as a physical layer security enhancement has recently drawn
considerable attention. While most existing works focus on communication systems with a …

A cooperative jamming protocol is studied in this paper and its ability to protect the
communications of a pair of users in the presence of an eavesdropper. Communication of …
