JANUS-based services for operationally relevant underwater applications
(CMRE, 2017/11)
This paper presents the design, test, and experimentation at sea of four JANUS-based services for operationally relevant underwater applications: 1) first contact and language switching; 2) transmission of automatic ...
A paradigm shift of interoperable submarine rescue operations: the usage of JANUS during the Dynamic Monarch 2017 exercise
(CMRE, 2019/05)
The NATO Centre for Maritime Research and Experimentation (CMRE) participated for the first time in the Dynamic Monarch submarine rescue exercise, bringing to the operational players a new interoperable digital underwater ...
Experimental evaluation of Net-LBL: an acoustic network-based navigation system
(CMRE, 2019/06)
This paper describes the use and in-field evaluation of a Networked-Long Base Line system (Net-LBL) where a network of underwater nodes cooperate to support the localisation and navigation of mobile vehicles. To avoid the ...
A distributed ID assignment and topology discovery protocol for underwater acoustic networks
(CMRE, 2017/11)
This paper presents a new protocol to self assign node IDs in an Underwater Acoustic Network (UAN). The proposed solution, termed DIVE for Distributed Id assignment and topology discoVEry, is fully distributed and ...
Toward the development of secure underwater acoustic networks
(CMRE, 2019/05)
Underwater acoustic networks (UANs) have been recognized as an enabling technology for various applications in the maritime domain. The wireless nature of the acoustic medium makes UANs vulnerable to various malicious ...
Secure underwater acoustic networks: current and future research directions
(CMRE, 2019/06)
Underwater Acoustic Networks (UANs) are widely used in various applications such as climate change monitoring, pollution control and tracking, tactical surveillance and offshore exploration. However, limited consideration ...
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 ...
Collaborative hybrid ARQ for CDMA-based reliable underwater acoustic communications
(CMRE, 2019/05)
Achieving high throughput and reliability in underwater acoustic networks is a challenging task due to the bandwidth-limited and unpredictable nature of the channel. In a multi-node structure, such as in the Internet of ...
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 ...
Performance evaluation of underwater medium access control protocols: at-sea experiments
(CMRE, 2019/06)
In this paper, we investigate the performance of three medium access control (MAC) protocols (CSMA, TLohi, and DACAP) representing simple, intermediate, and fully negotiated protocols, to access the underwater acoustic ...
