Abstract:
Multiple geo-replicated and independent IoT (Internet of Things) hubs configured as servers with storage capacities are utilized and span across various regions in the world, to each of which IoT devices can connect and transmit telemetry data. The IoT devices, configured with sensors to generate telemetry data (e.g., temperature, pressure, etc.), can fail over to another geo-replicated IoT hub (the “target geo-replicated IoT hub”) when one IoT hub experiences technical failures or the IoT device changes location to a region which is covered by the target IoT hub. Upon receiving a connection request from the IoT device, the target geo-replicated IoT hub submits a proposal to available geo-replicated IoT hubs for ownership over the IoT device, that is, receive data from and transmit messages to the IoT device. A quorum is sought so that all IoT hubs are in agreement as to a current owner of the IoT device.
