UWASNs consist of sensor nodes and vehicles which operate by exchanging configuration, location and movement information, and relaying monitored data to an onshore station.
IEC and ISO Joint Technical Committee (JTC 1) develops International Standards for information technology. JTC 1 Subcommittee 41, covers the internet of things and related technologies. It has developed the ISO/IEC 30140 series of Standards for UWASNs, which aims to provide general requirements, guidance and facilitate designers and developers of UWASNs for different applications and services.
Two new Parts were published recently: ISO/IEC 30140-3: 2018, describing UWASN interfaces between different physical and functional entities, and ISO/IEC 30140-4:2018, which specifies interoperability between the selected physical entities of UWASNs.
These Standards also contain entity models and high-level interface guidelines supporting interoperability among UWASNs, in order to provide the essential construction information that will help guide architects, developers and implementers of UWASNs. They also provide high-level functional models related to underwater sensor nodes, and relationships among the nodes for constructing an architectural perspective of UWASNs.
