Transmission of subscription-based messages to Internet of Things (IoT) devices

A method for sending subscription-based messages to devices, the method comprising:

• receiving a message associated with a defined topic;
• identifying a first subset of devices that subscribe to the defined topic;
• providing, to a message queue, a first subset of messages for transmission to devices indicated in the first subset of devices;
• identifying a second subset of devices subscribed to the defined topic;
• and
• providing, to the message queue, a second subset of messages for transmission to devices indicated in the second subset of devices, wherein the second subset of messages includes an increased subset size as compared to the first subset of messages, and the subset size is increased at a rate to enable sending the message to a plurality of devices subscribed to the defined topic within a defined time period.

A system for sending subscription-based messages to Internet of Things (IoT) devices, the system device comprising:

• a processor;
• a memory device including a data store to store a plurality of data and instructions that, when executed by the processor, cause the processor to:
• receive a message associated with a defined topic;
• identify a first page of IoT devices from a plurality of IoT devices that subscribe to the defined topic;
• provide a first page of messages to a message queue for transmission to IoT devices indicated in the first page of IoT devices, the first page of messages including copies of the message associated with the defined topic;
• identify a second page of IoT devices from the plurality of IoT devices that subscribe to the defined topic;
• and
• provide a second page of messages to the message queue for transmission to IoT devices indicated in the second page of IoT devices, the second page of messages including copies of the message associated with the defined topic, wherein the second page of messages includes an increased number of messages as compared to the first page of messages, and the increased number of messages is defined in part by a page size increase function which increases at a rate to enable sending the messages to the plurality of IoT devices subscribed to the defined topic within a defined time period.
