Abstract

The techniques disclosed herein provide improvements over existing systems by dynamically controlling communication connections between two or more computing devices based on the detection of specific events. Instead of requiring a device, such as an IoT device, to be continually connected to a network or a remote device, the techniques disclosed herein enable the device to remain offline until a specific event is detected. The disclosed technologies can avoid always-on network configurations while providing a desired functionality for an IoT device. For instance, some devices only connect with other computing devices or at network in response to detection of an event, then disconnect after an exchange of specific information. Such technologies can significantly reduce the power consumption of a device by only invoking connections at appropriate times.
