Summary

In Internet of things (IoT) environments, constrained devices, equipped with various low-power wireless interfaces, have connection capability to locally available networks for the purpose of interacting with the real world. Constrained devices have many different characteristics. Recommendation ITU-T Y.4451 specifies the framework of constrained device networking in the Internet of things (IoT) environments. This Recommendation therefore describes the concept and features of constrained device networking as well as network architectures of constrained device networking including functional requirements, such as fragmentation, reassembly, header compression, address configuration, network management, multi-hop routing protocol and higher layer considerations.

This Recommendation specifies the framework of constrained device networking in the Internet of things (IoT) environments with respect to IoT device communications. This Recommendation describes the concept of constrained device networking in the IoT environments and the communication of constrained devices. This Recommendation also describes network architecture and mechanisms of constrained device networking.
