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 ...
A modem design for underwater acoustic networking in the High North
(CMRE, 2019/05)
We design a software modem for long range underwater acoustic communications in ice-covered oceans. The modem is equipped with three coded modulation schemes achieving 1.8, 21.4 and 96.2 bps, respectively. In addition, we ...
On adaptive modulation for low SNR underwater acoustic communications
(CMRE, 2019/05)
This paper deals with adaptive underwater acoustic (UWA) communications where the receiver must operate at low signal-to-noise ratios (SNRs). The proposed modem is equipped with a set of direct sequence spread spectrum ...
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 ...
Underwater communications research and development at CMRE
(CMRE, 2019/06)
A key to developing autonomous maritime systems for NATO is communication among data gathering platforms below and above the water. However, unlike the mature technologies that are used for terrestrial networks, underwater ...
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 ...
Collaborative multistatic ASW using AUVs: demonstrating necessary technologies
(NURC, 2009/12)
Many research laboratories and several nations are showing an interest in the 'underwater networked battlespace' in which a combination of stationary and mobile underwater platforms communicate wholly or partially by the ...
