p>The attenuation of global positioning system (GPS) in water medium makes localization of autonomous uderwater vehicles (AUVs) particularly challenging. The long baseline (LBL) positioning system can extend GPS using beacons as references. This work aims at building an acoustic LBL-based system able to localize AUVs operating in swarms thanks to a...

The Autonomous Underwater Vehicles (AUVs) in-dustry is still awaiting its Henry Ford to bring to the market solutions that are well adapted to the challenge of underwater exploration. This will certainly be done by the advent of small connected drones equipped with small sensors and embedded devices, allowing AUVs to operate in a coordinated swarm,...

Underwater Acoustic Sensor Networks (UWASNs) consist of a variable number of autonomous sensors or vehicles that are deployed over a given area to perform smart sensing and collaborative monitoring tasks. In UWASNs, sensor localization plays a critical role. Motivated by the advent of embedded systems and their widespread adoption in localization,...

Our ultimate objective is to develop an underwater embedded system implementing image processing capabilities, that can be integrated to Autonomous Underwater Vehicles and diving Sonars. In this scope, this paper aims at presenting a technical study of a set of image processing techniques and their applications in underwater environment. It gives a...

Many embedded systems have been developed for terrestrial sensor localization, however, they are not applied directly to underwater sensor localization because of attenuation of GPS and RF signals underwater, making localization underwater particularly challenging. This paper presents the design, implementation and performance measurement of a digi...

This paper presents an embedded wireless Internet of Things architecture, integrating real time embedded systems that communicate underwater through acoustic signals. The proposed architecture is based on an ultra-low-power Flash Micro-controller that manages communications with sensors, and synchronization between the whole system through wireless...

This paper showed the challenge of embedded systems and Internet of Things in underwater environment. We presented solutions to improve IoT communication underwater by means of high performance algorithms and software, embedded in digital real-time platforms. The design, simulations and experimental measurements at sea were presented.

This work proposes the design and realization of an embedded system that implements astronomic equations in order control the movement of a photovoltaic solar tracker in the direction of the maximum sunshine along the day.
