Overview - What ISO/IEC 30140-1:2018 covers
ISO/IEC 30140-1:2018 defines an overview and requirements for underwater acoustic sensor networks (UWASN). As Part 1 of the ISO/IEC 30140 series, it summarizes the main characteristics of UWASN, analyzes how underwater acoustic propagation differs from terrestrial networks, and derives specific and general requirements for reliable underwater sensing and communications. The standard targets the unique physical, protocol and deployment aspects of underwater communication driven by acoustic channels.
Key technical topics and requirements
ISO/IEC 30140-1 focuses on the practical technical constraints and design considerations for UWASN, including:
- Propagation variability and channel effects: attenuation, high propagation delay, multipath, Doppler spread and ambient noise that affect acoustic links.
- Comparison with terrestrial networks: differences in physical media (acoustic vs radio/optical), transducer behavior (omni-directional vs directional), housing and cost implications.
- Network architectures and scales: cluster, ad-hoc and gateway-based topologies; 2D and 3D UWASN deployment models and node placement.
- Device and protocol requirements: underwater acoustic modem features, cross-layer design, time synchronization, energy-saving modes (active/sleep scheduling) and routing strategies adapted to high-latency, high-loss channels.
- Advanced techniques: recommendations on network coding, data compression, delay- and disruption-tolerant networking (DTN) and considerations for localization and 3D relay nodes.
- Operational constraints and system requirements: deployment depth considerations, energy harvesting options, physical housing and environmental robustness.
These topics inform practical requirements for hardware, firmware and network protocols to increase reliability, efficiency and interoperability in UWASN deployments.
Applications - who uses this standard and why
ISO/IEC 30140-1 is relevant to organizations and professionals involved in:
- Marine researchers and oceanographers deploying sensor arrays for environmental monitoring and biological studies.
- Offshore and oil & gas operators monitoring pipeline leakages and subsea infrastructure.
- Aquaculture and fish farming companies using sensors for health and water quality monitoring.
- Port and harbour security, defense and coastal surveillance integrators.
- Manufacturers of underwater acoustic modems, transducers, and sensor platforms.
- System integrators, standards bodies and IoT architects designing interoperable underwater solutions.
By following the standard, users can design UWASN systems that address acoustic channel challenges, support expected use cases, and meet recommended operational requirements.
