Learning-Based Multi-Domain Anti-Jamming Communication with Unknown Information [PDF]

open access: goldElectronics, 2023
Due to the open nature of the wireless channel, wireless networks are vulnerable to jamming attacks. In this paper, we try to solve the anti-jamming problem caused by smart jammers, which can adaptively adjust the jamming channel and the jamming power ...

Compromise-resilient anti-jamming communication in wireless sensor networks [PDF]

open access: yesWireless Networks, 2011
Jamming is a kind of Denial-of-Service attack in which an adversary purposefully emits radio frequency signals to corrupt the wireless transmissions among normal nodes. Although some research has been conducted on countering jamming attacks, few works consider jamming attacks launched by insiders, where an attacker first compromises some legitimate ...

Survey on cognitive anti‐jamming communications [PDF]

open access: yesIET Communications, 2020
In this study, the authors review various jamming and anti‐jamming strategies in the context of cognitive radios (CRs). The study explores different jamming models and classifies them according to their functionality. Furthermore, a study of jamming detection techniques is provided to enable a CR to identify different jamming signals.

Heterogeneous Spectral-Spatial Network With 3D Attention and MLP for Hyperspectral Image Classification Using Limited Training Samples

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Methods based on convolutional neural networks (CNNs) have become a vital offshoot for hyperspectral image (HSI) classification. In recent years, the 3-D CNN (3-DCNN) has become dominant due to its excellent capability of extracting features.
