Overview
ISO/IEC 29182-4:2013 - part of the Sensor Network Reference Architecture (SNRA) series - defines high-level entity models for sensor networks. The standard describes how physical entities (for example, sensor nodes, gateways, service providers and users) and functional entities (for example, data acquisition, communications, data processing, device management) are modeled and related within the SNRA. Its goal is to facilitate sensor network design, improve interoperability, and support plug-and-play composition of sensor network components.
Note: the ISO/IEC 29182 series provides guidance rather than mandatory compliance; users must ensure local or application-specific requirements are met.
Key topics
- Physical entity models
- Sensor nodes and their subcomponents (sensors, actuators, power, memory, processor, communications module)
- Gateways, access/backbone networks, service providers and users
- Functional entity models
- Layered functional view: hardware layer, basic functions layer, service layer, application layer, and cross-layer management
- Functional services such as data acquisition, actuation, data communications, storage, device/sensor identification, time synchronization, group management/clustering, and collaborative information processing
- Interrelationships
- Mapping between physical and functional entities (which functions can run on which physical devices)
- Taxonomies and input–output characterizations for sensors (analog/digital), and example functions like self-localization and service discovery
- Supporting concerns
- Device management, resource and service management, security management, QoS, privacy and safety management, and system monitoring
- Reference linkage to other SNRA parts: vocabulary (Part 2), architecture views (Part 3), interfaces (Part 5), interoperability guidelines (Part 7), with Part 6 (applications) under preparation.
Applications
ISO/IEC 29182-4 is practical for projects that need a reusable architectural model for sensor networks and interoperable components:
- Designing and documenting sensor network architectures for IoT, environmental monitoring, smart cities, industrial automation and other sensor-rich systems
- Specifying functional responsibilities (e.g., where to implement data processing, localization, security)
- Defining plug-and-play component expectations for vendors and integrators
- Informing interface and profile development (used with Parts 5 and 7 for interoperability)
Who should use this standard
- Sensor network designers and architects
- Software and firmware developers for sensor nodes, gateways and services
- System integrators and solution providers aiming for interoperable, modular sensor systems
- Standards developers and testers creating conformance profiles or interface specifications
