Overview - ISO/IEC 30140-3:2018 (UWASN Entities and Interfaces)
ISO/IEC 30140-3:2018 is Part 3 of the ISO/IEC 30140 series that defines high-level entities and interfaces for Underwater Acoustic Sensor Networks (UWASN). The standard provides a reference architecture view that distinguishes physical entities (e.g., underwater acoustic sensor nodes, gateways, relay nodes) and functional entities (layered functions such as UWA‑PHY, UWA‑DL, UWA‑NWK, UWA‑BUN, UWA‑APS and cross‑layer management). Its objective is to support interoperability, common vocabulary and high‑level interface guidelines for architects, developers and implementers of UWASNs.
Key topics and technical scope
- Entity models: Definitions and categorizations of UWASN physical entities (domain, network, application) and functional entities that realize data, control and management tasks.
- Interfaces: Descriptions of interfaces between physical entities (Interface 1–5: e.g., User ⇄ UWA‑GW, UWA‑GW ⇄ relay, relay ⇄ sensor node, node ⇄ node) and between functional layers (UWA‑PHY ↔ UWA‑DL, UWA‑DL ↔ UWA‑NWK, UWA‑NWK ↔ UWA‑BUN, UWA‑BUN ↔ UWA‑APS, and UWA‑CLM to others).
- Service access points (SAPs): High‑level SAP definitions enabling modular service access across layers.
- Cross‑layer management: Functional entity (UWA‑CLM) guidance for information sharing across PHY, DL, NWK, BUN and APS.
- Interoperability focus: High‑level models and interface specifications to guide consistent implementations without prescribing specific acoustic waveforms or frequencies.
Note: the standard is application‑agnostic and deliberately does not mandate physical layer waveforms or operating frequencies. It advises implementers to observe regional noise and marine acoustic regulations (including provisions for known submarine emergency bands where applicable).
Practical applications and users
- Who uses it: system architects, network designers, marine researchers, OEMs of underwater sensors, integrators of UUV/USV platforms, and standards/compliance engineers.
- Use cases:
- Designing interoperable UWASN deployments for environmental monitoring, pollution detection, pipeline leak detection, marine biology studies, surveillance and asset monitoring.
- Specifying modular software/hardware interfaces for sensor nodes, gateways and gateways-to-backhaul links.
- Creating test plans and conformance frameworks for multi‑vendor UWASN components.
- Benefits: promotes modular design, simplifies integration of heterogeneous nodes, and clarifies layer responsibilities to speed development and improve robustness.
