Abstract

Connecting an IoT device enabling a new function of another IoT device. An IoT hub scans a network segment for presence of an IoT device. Upon detecting the IoT device, a device response pattern is received. The device response pattern is compared with stored response patterns. A matching stored response pattern is selected which has a similarity to the device response pattern. A pattern difference is derived. Related device information is transformed into a device signature for the IoT device. The device signature is transferred to a discovery engine. The device signature is compared to stored signatures and protocol information. A matching stored signature and protocol information is transferred to the IoT hub. The IoT hub compares the new function with functions of other connected IoT devices. Upon finding a matching other IoT device, the other IoT device is offered a usage of the new function and protocol information.
