IoT Internet of Things

ISO/IEC 20922:2016 is a Client Server publish/subscribe messaging transport protocol. It is light weight, open, simple, and designed so as to be easy to implement. These characteristics make it ideal for use in many situations, including constrained environments such as for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts where a small code footprint is required and/or network bandwidth is at a premium.

Cellular IoT support and evoluation for the 5G system (SP-18118) is a 3GPP completed work item (WID) for Release 16 as part of the stage 2 work (5G phase 2).

The OASIS COEL specification provides a privacy-by-design framework for the collection and processing of behavioural data. It is uniquely suited to the transparent use of dynamic data for personalised digital services, IoT applications where devices are collecting information about identifiable individuals and the coding of behavioural data in identity solutions. The specification pseudonymises personal data at source and maintains a separation of different data types with clearly defined roles & responsibilities for all actors. All behavioural data are defined as event-based packets. Every packet is connected directly to an individual and can contain a summary of the consent they provided for the processing of the data.

SG20 develops international standards to enable the coordinated development of IoT technologies, including machine-to-machine communications and ubiquitous sensor networks. A central part of this study is the standardization of end-to-end architectures for IoT, and mechanisms for the interoperability of IoT applications and datasets employed by various vertically oriented industry sectors.

This document provides a standardized IoT Reference Architecture using a common vocabulary, reusable designs and industry best practices. It uses a top down approach, beginning with collecting the most important characteristics of IoT, abstracting those into a generic IoT Conceptual Model, deriving a high level system based reference with subsequent dissection of that model into five architecture views from different perspectives.

In addition to interoperability and security that are two recognized key enablers to the development of large IoT systems, a new one is emerging as another key condition of success: virtualization. The deployment of IoT systems will occur not just within closed and secure administrative domains but also over architectures that support the dynamic usage of resources that are provided by virtualization techniques over cloud back-ends.

The present document is addressing the issues related to the introduction of AI into IoT systems and, as first priority, into the oneM2M architecture. The following points are discussed:

The purpose of this Group Specification is the (preliminary) definition of a standard API for Context Information Management (CIM-API) enabling close to real-time access to information coming from many different sources (not only IoT). The document shall define how such an API enables applications to perform updates on context, register context providers which can be queried to get updates on context, query information on current and historic context information and subscribe for receiving notifications on context changes. The criteria for choice of the API characteristics shall be based on results in WI UC and WI GAP.

This document specifies the framework of a real-time IoT (RT-IoT) system, including:

The standard utilizes the advanced capabilities of the XMPP protocol, such as providing globally authenticated identities, authorization, presence, life cycle management, interoperable communication, IoT discovery and provisioning. Descriptive meta-data about devices and operations will provide sufficient information for infrastructural components, services and end-users to dynamically adapt to a changing environment. Key components and needs of a successful Smart City infrastructure will be identified and addressed. This standard does not develop Application Programming Interfaces (APIs) for existing IoT or legacy protocols.

This document specifies network models for IIoT connectivity and general compatibility requirements for devices and networks within IIoT systems in terms of:
