Abstract
A server device may receive from a first computing device current location information associated with the first computing device. The server device may estimate a travel radius of a second computing device based at least in part on location information previously received from the second computing device, and may determine that the travel radius of the second computing device overlaps a proximity radius of the first computing device. The server device may query the second computing device for updated location information. The server device may receive the updated location information for the second computing device, and may determine that the second computing device is physically located substantially within the proximity radius of the first computing device based at least in part on the updated location information. In response, the server device may send to the first computing device an identification of the second computing device.
