Abstract

Various examples are disclosed for performing dynamic chains of action for Internet-of-Things (IoT) devices. In some aspects, IoT event data is received from an IoT device. An IoT dependency graph is identified based on an initial IoT event specified by the IoT dependency graph. An IoT event subsequent to the initial IoT event is identified according to the IoT dependency graph. A command is transmitted to an IoT device to perform the IoT event.

First claim

What is claimed is:

1. A system, comprising:
at least one computing device; and
program instructions stored in at least one memory of the at least one computing device, wherein the instructions, when executed by at least one processor, cause the at least one computing device to at least:

identify an IoT dependency graph that is identified based on an initial IoT event specified by the IoT dependency graph corresponding to the IoT event data;
identify at least one IoT event subsequent to the initial IoT event in the IoT dependency graph;
determine, by a server-layer device of a computing environment comprising a server layer and an edge layer, that the IoT dependency graph is evaluable at the edge layer based on the IoT dependency graph specifying a single edge device as an edge device through which a respective one of a plurality of IoT devices in the IoT dependency graph perform network communications; and
transmit, by the server-layer device to the single edge device, the IoT dependency graph to the single edge device, wherein the single edge device transmits, to at least one IoT device, at least one command for the at least one IoT device to perform the at least one IoT event.
