Abstract: Various embodiments provide methods implemented by a requesting device and a responding device for collectively identifying one or more clusters of nearby computing devices by collaborating and sharing information. In various embodiments, the requesting device may send a distance threshold to responding devices, along with a request for grouping information about computing devices that are within the distance threshold of the responding devices. In response to receiving the request and distance threshold, each responding device may identify a number of other computing devices that are within the distance threshold and may send such information to the requesting device. The requesting device may identify one or more clusters of computing devices based on the received grouping information. By configuring responding devices to detect other computing devices within a modifiable distance threshold, the requesting device may dynamically adjust the size of identified clusters of computing devices.
