In the area of physical-layer security for wireless communications, jamming is one of the
methods that a malicious agent uses to actively attack legitimate nodes. The jammers make …

In this article, we investigate the physical layer security for a wireless communication system
consisting of a base station (BS) and a user (U) in the face of an eavesdropper (E). A friendly …

Active attacking in physical-layer security has not been significantly studied while potentially
causing serious consequences for the legitimate networks. In this paper, we propose a novel …

This paper deals with the use of jamming transmission for secure amplify‐and‐forward‐
based relay networks with total power constraints. An approach that the source and the relay …

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 …

Signal interference and packet collisions are typically viewed as negative factors that hinder
wireless communication networks. When security is the primary concern, signal interference …

This paper proposes to employ multiple cooperative jammers to reduce the secrecy loss due
to the correlation between main and wiretap channels. We consider slow-fading multiple …

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 …

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

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 …
