Bandwidth efficient concurrent localisation and communication in underwater acoustic networks
Sliwka, Jan; Munafò, Andrea; Petroccia, Roberto (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), ... -
Collaborative hybrid ARQ for CDMA-based reliable underwater acoustic communications
Rahmati, Mehdi; Pompili, Dario; Petroccia, Roberto (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 ... -
Cooperation and networking in an underwater network composed by heterogeneous assets
Braga, José; Martins, Ricardo; Petrioli, Chiara; Petroccia, Roberto; Picari, Luigi (CMRE, 2019/06)Underwater communication and robot technologies have grown rapidly in the last decade. Systems made of underwater unmanned vehicles have moved from single vehicle deployments to systems comprising teams of assets. As of ... -
Cooperative robotic networks for underwater surveillance: an overview
Ferri, Gabriele; Munafò, Andrea; Tesei, Alessandra; Braca, Paolo; Meyer, Florian; Pelekanakis, Konstantinos; Petroccia, Roberto; Alves, João; Strode, Christopher; LePage, Kevin D. (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 ... -
Deployment of a persistent underwater acoustic sensor network: the CommsNet17 experience
Petroccia, Roberto; Sliwka, Jan; Grati, Alberto; Grandi, Vittorio; Guerrini, Piero; Munafò, Andrea; Stipanov, Marin; Alves, João; Been, Robert (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 ... -
Development of a software-defined and cognitive communications architecture at CMRE
Petroccia, Roberto; Zappa, Giovanni; Furfaro, Thomas C.; Alves, João; D'Amaro, Luigi (2019/05)This paper presents an overview of the functionalities of the Cognitive Communications Architecture (CCA) that is currently under development at the NATO Science and Technology Organisation (STO) Centre for Maritime Research ... -
Experimental evaluation of Net-LBL: an acoustic network-based navigation system
Sliwka, Jan; Petroccia, Roberto; Munafò, Andrea; Djapic, Vladimir (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 ... -
Fostering the use of JANUS in operationally-relevant underwater applications
Petroccia, Roberto; Alves, João; Zappa, Giovanni (CMRE, 2017/11)This paper presents the use of JANUS in operationally-relevant underwater applications. JANUS is an open, simple and robust digital coding technology currently in process to become a NATO standard. Two underwater scenarios ... -
Increasing the operational safety of autonomous underwater vehicles using the JANUS communication standard
Ferreira, Fausto; Petroccia, Roberto; Alves, João (CMRE, 2019/05)Increasing the operational safety of Autonomous Underwater Vehicles (AUVs) is necessary to fully explore their potential. Currently, AUV operations are limited by several constrains including the need to guarantee no ... -
JANUS-based services for operationally relevant underwater applications
Petroccia, Roberto; Alves, João; Zappa, Giovanni (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 ... -
Localisation using undersea wireless networks
Munafò, Andrea; Sliwka, Jan; Petroccia, Roberto (CMRE, 2019/05)Underwater navigation for Autonomous Underwater Vehicles (AUVs) is a challenging task, requiring a trade-off between performance, costs and operational time. The project Network Long Base Line (Net- LBL) proposes a system ... -
Moving JANUS forward: a look into the future of underwater communications interoperability
Alves, João; Furfaro, Thomas C.; LePage, Kevin D.; Pelekanakis, Konstantinos; Petroccia, Roberto; Zappa, Giovanni (CMRE, 2017/11)In the past 8 years, the Centre for Maritime Research and Experimentation (CMRE) has developed, tested and promoted JANUS - a robust and simple modulation and coding scheme to be used as the first standard to support ... -
