Routing for low latency underwater acoustic network-communication is investigated. The application is monitoring of ice-threats to offshore operations in the Arctic - to provide warnings that enable operators to react to such threats. The scenario produces relatively high traffic load, and the netwo...

Underwater networks that are designed to carry high-priority data at a relatively high traffic load should employ network protocols that emphasize low delay and adequate reliability at the expense of energy. ICRP (Information-Carrying based Routing Protocol), originally proposed by Wei Liang et al. ...

The SEATONOMY methodology provides a structured approach for design, development and validation of mobile autonomous maritime operations and systems. The goal is to achieve this by providing system developers of autonomous systems with suitable guidelines, principles, best practices and tools. The m...

OSS is a real-time supervising concept for marine operations and management based on data assimilation and integrated measurements and models. OSS is composed of an underwater sensor network, communication links to computers running ocean models, computer ocean models and a data assimilation tool wh...

The use of hydrodynamic modeling to optimize the placement of sensor nodes with respect to reduction of uncertainty in sea current modeling is demonstrated. This is done under the additional constraint that the nodes should constitute a connected underwater acoustic communication network. For the co...

Prediction of acoustic connectivity is the key to successful deployment of underwater acoustic communication systems, and in particular to deployment of multi-node networks. The connectivity is given mainly by the local sound propagation characteristics, which in turn are given by the spatial and te...
