Abstract
Devices and methods are provided for determining the proximity of client nodes within a wireless-enabled communication environment. A first client node comprises a database containing identification data associated with a plurality of wireless network access nodes and fingerprint data associated with the client node and a plurality of second client nodes. As the fingerprint information is updated, it is processed by the first client node to identify second client nodes that have matching, or similar, fingerprint information. Those that do are determined to be within a viable device-to-device (D2D) communication range.
