Popis: | This paper concerns the design and implementation of a novel system for diving operations based on an efficient underwater acoustic network. The proposed system is composed of both static underwater nodes and divers that are equipped with acoustic modems and underwater tablets. The SUNSET Software Defined Communication Stack (S-SDCS) has been used to provide multi-hop networking capabilities. Novel image compression and transmission modules have been designed and implemented in S-SDCS. In addition, the localization module has been enhanced to increase the safety of the divers whose positions can be locally and remotely monitored. These modules interact with an innovative mobile application running on the underwater tablet thus enabling divers communication and remote position estimation and monitoring. In addition, divers can acquire and share pictures with other operators in real-time. The user interface of the application has been designed according to diver needs and feedback thus making it perfectly suitable for several diving scenarios. The system has been tested in several at-sea campaigns considering different application scenarios. The achieved results confirm that the proposed system is suitable for several diving experiences, enabling novel application scenarios while increasing divers safety. |
