This work describes a system for acoustic‐based navigation that relies on the addition of localization services to underwater networks. The localization capability has been added on top of an existing network, without imposing constraints on its structure/operation. The approach is based on the inclusion of timing information within acoustic messages through which it is possible to know the time of an acoustic transmission in relation to its reception. Exploiting such information at the network application level makes it possible to create an interrogation scheme similar to that of a long baseline. The advantage is that the nodes/autonomous underwater vehicles (AUVs) themselves become the transponders of a network baseline, and hence there is no need for dedicated instrumentation. The paper reports at sea results obtained from the COLLAB–NGAS14 experimental campaign. During the sea trial, the approach was implemented within an operational network in different configurations to support the navigation of the two Centre for Maritime Research and Experimentation Ocean Explorer (CMRE OEX) vehicles. The obtained results demonstrate that it is possible to support AUV navigation without constraining the network design and with a minimum communication overhead. Alternative solutions (e.g., synchronized clocks or two‐way‐travel‐time interrogations) might provide higher precision or accuracy, but they come at the cost of impacting on the network design and/or on the interrogation strategies. Results are discussed, and the performance achieved at sea demonstrates the viability to use the system in real, large‐scale operations involving multiple AUVs. These results represent a step toward location‐aware underwater networks that are able to provide node localization as a service.

“…Regarding software development, one of the simplest approaches is to run mature software suites, such as TCP/IP [8], or terrestrial sensor network protocols [9], on top of acoustic modems. Although this approach requires less development time, efficiency of protocols or algorithms is usually compromised because they are designed under a different set of assumptions.…”

Advancement in acoustic modem technology has gradually brought underwater network into real life. Despite high cost of sea testing, there have been initial realization effort, such as Sea-Web, Aqua-Net, SUNSET, etc. As the main developers of Aqua-Net, through extensive testing experiences at different scales, we have recognized shortcomings of AquaNet and decided to design and implement the next generation of it. In this paper, we introduce SeaLinx as a new protocol stack architecture for underwater networking which (i) enables users to exploit their hardware more efficiently by allowing applications to run simultaneously on a modem, and (ii) provide better support for cross-layer communication.

“…Toso et al then launched an experiment using SUNSET for dynamic source routing with 6 nodes [30] in a recent lake test. In the same year, Caiti et al reported experiment results from their 2011's sea trial in Trondheim, Norway [31] which ran the TCPIIP stack on top of acoustic modems.…”

Underwater Wireless Networks (UWNs) have gained significant attention in recent years given their ability to expand underwater monitoring and detection applications. In this paper, we share our experience from a recent field experiment in the Atlantic Ocean, in which we have deployed an 11 node UWN. We discuss the system architecture, both hardware and software, and evaluate two new network protocols and one existing network protocol for real-world performance. Additionally, we provide insight on how the physical environment and surroundings impact the performance of the networked system. This work will share our practical issues in real systems and inspire new advances in the area of UWN research.
