INTERNET OF THINGS DEVICE HIERARCHIES

摘要

In embodiments, Internet of Things (IoT) devices may be organized according to an IoT device hierarchy, which may include parent and/or child associations between resources associated with IoT devices and/or with groupings of IoT devices. IoT devices wishing to support an IoT device hierarchy may utilize an extended IoT device resource model which provides for IoT device hierarchy information and interfaces to be provided by supporting IoT devices. A supporting resource may have one or more parent properties and/or child properties which may identify, respectively, parent or child resources which are associated with the resource. In various embodiments, these parent properties and/or child properties may include uniform resource identifiers (URI). A supporting resource may also identify an interface type for a hierarchical access interface, through which one or more descendant resources may be accessed through a single command. Other embodiments may be descried and/or claimed.

主权项

1. An Internet of Things (IoT) device, comprising:
a resource; and an actuator coupled with the resource to set one or more attributes of the resource; wherein:
the resource is associated with a unique resource identifier (URI) and a plurality of properties;the URI uniquely identifies the resource among a plurality of resources disposed among IoT devices of an IoT device hierarchy; andthe plurality of properties includes a hierarchical interface property that indicates the resource is accessible in a hierarchical manner, wherein the hierarchical interface property is at least one of a parent URI property or a child URI property;the parent URI property, when included, has a property value that identifies a parent URI of a parent resource of the plurality of resources which has a parent resource relationship to the resource in the IoT device hierarchy; andthe child URI property, when included, has a property value that identifies a child URI of a child resource of the plurality of resources which has a child resource relationship to the resource.
