Fibre optic sensing is a key technology for a variety of underwater sensing and monitoring applications. Fibre optic acoustic sensors are mainly based on interferometric detection approach where the acoustic pressure-induced phase shift of light has been used as sensing principle. Recently, fibre optic acoustic sensors based on speciality fibres like Photonic Crystal Fibre (PCF) were reported. However,...
Design of simple and efficient routing protocols for underwater acoustic sensor networks is a difficult subject because they have to cope with the challenging and variable characteristics of the water medium. With the participation of autonomous underwater vehicles in underwater networks, mobility has become a more important matter to deal with in protocol design. Adding to that, it is also not common...
This article describes the initial planning and outcomes of validation and demonstration efforts for oceanographic sensors in the EU-funded project NeXOS. The project has developed novel, multi-functional optical and acoustic sensors for environmental monitoring and mapping. These sensors are subject to validation and demonstration in real sea conditions. Procedures for validations are described,...
