TS-MUWSN: Time synchronization for mobile underwater sensor networks [PDF]
, 2016 Time synchronization is an important, yet challenging, problem in underwater sensor networks (UWSNs). This challenge can be attributed to: 1) messaging timestamping; 2) node mobility; and 3) Doppler scale effect. To mitigate these problems, we present an

The Influence of MAC Protocol on a Non-Synchronous Localization Scheme in Large-Scale UWSNs
IEEE Access, 2018 Localization plays a more and more important role in underwater wireless sensor networks (UWSNs). But in the large-scale UWSNs, the localization algorithm can’t be realized for the continuous packet collision.

Underwater acoustic multiplexing communication by pentamode metasurface [PDF]
Journal of Physics D: Applied Physics, 2021 Abstract As the dominant information carrier in water, the acoustic wave is widely used for underwater detection, communication and imaging. Even though underwater acoustic communication has been greatly improved in the past decades, it still suffers from slow transmission speeds and low information capacity.

Resonance-Based Time-Frequency Manifold for Feature Extraction of Ship-Radiated Noise
Sensors, 2018 In this paper, a novel time-frequency signature using resonance-based sparse signal decomposition (RSSD), phase space reconstruction (PSR), time-frequency distribution (TFD) and manifold learning is proposed for feature extraction of ship-radiated noise,
