We consider a wireless network scenario in which the communicating nodes are assisted by
a number of jammers. The goal of the jammers is to obstruct potential eavesdroppers while …

We present a collision-free jammer selection policy for enhanced wireless secrecy.
Jammers, selected from the neighbors of a source, are friendly in the sense that they are …

We present a jamming protocol for secrecy-enhanced wireless networks in which otherwise
silent devices are selected as jammers to cause interference to potential eavesdroppers …

Jamming emits white Gaussian noise that causes interference to both the legitimate receiver
and eavesdropper. It has been an effective method for improving physical-layer security in …

This paper proposes a novel anti-eavesdropping scheme by introducing artificial noise
caused by friendly jammers deployed in wireless networks. In particular, we propose an …

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

In this paper, we consider deceptive friendly jammers in a half-duplex random wireless
network against a group of adaptive eavesdroppers. The destinations, eavesdroppers and …

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 investigates studies how cooperative jamming helps improve the secrecy
throughput of large decentralized networks where the locations and channel state …

To protect confidential communications from eavesdropping attacks in wireless networks, we
propose a novel anti-eavesdropping scheme named AE-Shelter. In our proposed scheme …
