A scalable algorithm for tracking an unknown number of targets using multiple sensors
(CMRE, 2019/06)
We propose an algorithm for tracking an unknown number of targets based on measurements provided by multiple sensors. Our algorithm achieves low computational complexity and excellent scalability by running belief propagation ...
Deployment of a persistent underwater acoustic sensor network: the CommsNet17 experience
(CMRE, 2019/05)
This paper presents the experimental activities performed by the NATO STO Centre for Maritime Research and Experimentation (CMRE) during the CommsNet17 trial where a persistent Underwater Acoustic Sensor Network (UASN) was ...
Cooperative robotic networks for underwater surveillance: an overview
(CMRE, 2019/06)
Underwater surveillance has traditionally been carried out by means of surface and undersea manned vessels equipped with advanced sensor systems. This approach is often costly and manpower intensive. Marine robotics is an ...
Tracking an unknown number of targets using multiple sensors: a belief propagation method
(CMRE, 2019/06)
We propose a multisensor method for tracking an unknown number of targets. Low computational complexity and very good scalability in the number of targets, number of sensors, and number of measurements per sensor are ...
Real-time clock synchronisation in underwater acoustic networks
(CMRE, 2019/06)
This paper proposes an algorithm for real-time clock synchronisation in underwater acoustic networks. The algorithm models modem clocks as linear functions and embeds the data necessary for the clock synchronisation procedure ...
Distributed underwater glider network with consensus Kalman filter for environmental field estimation
(CMRE, 2019/06)
A distributed coordinated dynamic sensor network for optimal environmental field estimation is proposed and tested on simulated and real data. The architecture is used to distribute the estimation of 3D timevarying fields ...
Distributed information fusion in multistatic sensor networks for underwater surveillance
(CMRE, 2019/06)
Surveillance in antisubmarine warfare has traditionally been carried out by means of submarines or frigates with towed arrays. These techniques are manpower intensive. Alternative approaches have recently been suggested ...
Bandwidth efficient concurrent localisation and communication in underwater acoustic networks
(CMRE, 2019/05)
Localisation is essential for an Autonomous Underwater Vehicle (AUV) to perform its mission and to georeference any data acquired during the dive. When the AUV is part of a heterogeneous underwater acoustic network (UAN), ...
An adaptive cross-layer routing protocol for underwater acoustic networks
(2019/05)
This short paper presents an adaptive cross-layer routing protocol for Underwater Acoustic Networks (UANs). The proposed solution, termed NADIR for Network Aware aDaptIve Routing, is fully distributed and self-adaptive. ...
Dynamic underwater glider for environmental field estimation
(CMRE, 2019/06)
A coordinated dynamic sensor network of autonomous underwater gliders to estimate three-dimensional time-varying environmental fields is proposed and tested. Integration with a network of surface relay nodes and asynchronous ...
