Abstract
A mobile device indexing system includes a plurality of edge nodes in communication with each other across a communication network and a plurality of mobile devices configured to communicate with the edge nodes. Each mobile device has both computing and communication functionalities. A separate mobile device index is maintained at each one of the plurality of edge nodes. Each mobile device index is a geographical spatio-temporal index having entries for a unique set of mobile devices derived from the plurality of mobile devices. Each unique set contains only mobile devices registered to the edge node associated with that mobile device index.
