Acoustic communication is the most common technique to communicate with an autonomous underwater vehicle (AUV) during its mission. Furthermore, this communication channel is often used for ranging, to support the navigation of the vehicle and localize it in world coordinates, whereas the vehicles dead reckoning only gives a relative position to a starting point. Due to the severe multipath propagation...
In passive acoustic monitoring, source localization using multipath propagation can be challenging whenever the source-receiver configuration leads to overlapping multipath arrival patterns. We propose a single-hydrophone model-based method with matched-impulse response (IR) processing that exploits unresolved multipath arrival patterns to locate the source in 3D, making the best use of the bathymetric...
The development of new cost-effective and compact multifunctional sensor systems for a sustainable and integrated approach to ocean monitoring is the main objective of the NeXOS project. Within this context, the company SMID Technology manufactured two passive acoustic sensor systems, A1 and A2, as a new type of small dimension, low power and innovative digital hydrophone systems. A1 is a standalone...
The cooperation and networking in heterogeneous underwater networks composed of vehicles running different control software and multi-vendor modems are a key issue due to the lack of standard. Since the interaction between different and multiple assets is of paramount importance for several application scenarios, in this paper we first present the new SUNSET Software Defined Communication Stack (SDCS)...
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...
