Full title and description

ISO/IEC 30165:2021 — Internet of Things (IoT) — Real-time IoT framework. This international standard specifies a framework for real-time IoT (RT‑IoT) systems, defining a conceptual model based on the domain-based IoT reference architecture and describing how real-time parameters affect system design across time, communication, control and computation viewpoints.

Abstract

ISO/IEC 30165:2021 defines the RT‑IoT system conceptual model (building on ISO/IEC 30141) and explains the impacts of real‑time constraints. It organizes considerations into four viewpoints — time, communication, control and computation — and provides a lightweight framework to guide architects and implementers when designing IoT systems with real‑time requirements.

Scope

This document specifies the framework of a real‑time IoT (RT‑IoT) system. It provides a conceptual model for RT‑IoT based on the domain‑based IoT reference model (ISO/IEC 30141) and discusses how time‑related parameters influence design and operation across four viewpoints: time (temporal requirements and synchronization), communication (latency, jitter and QoS), control (closed‑loop behaviour and stability) and computation (scheduling, resource constraints and real‑time processing). The standard is intended to guide architects, designers and system integrators in identifying and documenting real‑time concerns within IoT solutions.

Key topics and requirements

• RT‑IoT conceptual model mapped to the domain‑based IoT reference architecture (ISO/IEC 30141).
• Definition and classification of real‑time parameters relevant to IoT deployments (latency, jitter, deadlines, synchronization).
• Four‑viewpoint analysis: time, communication, control and computation—how each viewpoint affects design and verification.
• Guidance on expressing real‑time requirements and constraints for sensors, edge devices, gateways and cloud components.
• Considerations for QoS, network performance, time synchronization, control‑loop stability and computational scheduling.
• Emphasis on system‑level thinking to balance real‑time needs with scalability, interoperability and maintainability.

Typical use and users

ISO/IEC 30165:2021 is used by IoT system architects, platform designers, embedded/firmware engineers, edge computing teams, systems integrators and researchers who need to design or evaluate IoT solutions with real‑time constraints. It is useful when specifying requirements, performing architectural tradeoffs, or aligning implementations to a common conceptual framework that highlights time‑sensitive behaviours across distributed IoT components.
