1. A client node, comprising:
- a database comprising 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, the fingerprint data including signal strength data of a plurality of mobile or physical wireless access points measured by each of the client node and the plurality of second client nodes; and
processing logic configured to process the signal fingerprint data to determine a proximity between the client device and an individual second client node of said plurality of second client nodes and to identify an individual second client node of said plurality of second client nodes within a viable device-to-device (D2D) communication range, the viable D2D communication range determined to exist in response to a match between a first fingerprint of the client node and a second fingerprint of the individual second client node, the matching first and second fingerprints indicating that a same set of mobile or physical wireless access points measured by the client node and the second client node have about equal signal strengths,wherein said processing logic is further operable to initiate a D2D communications session with said individual second client node that is within said viable D2D communication range.

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.

12. A method for using a client node to initiate a device-to-device (D2D) communications session, comprising:
-
using a database comprising identification data associated with a plurality of wireless network access nodes and signal fingerprint data associated with the client node and a plurality of second client nodes, the fingerprint data including signal strength data of a plurality of mobile or physical wireless access points measured by each of the client node and the plurality of second client nodes; and using processing logic to determine a proximity between the client device and an individual second client node of said plurality of second client nodes, to process the signal fingerprint data to determine whether a match between a first fingerprint of the client node and a second fingerprint of the individual second client node exists, the matching first and second fingerprints indicating that a same set of mobile or physical wireless access points measured by the client node and the second client node have about equal signal strength, and to identify the individual second client node of said plurality of second client nodes is within a viable D2D communication range when the first fingerprint matches the second fingerprint, wherein said processing logic is further used to initiate a D2D communications session with said individual second client node that is within said viable D2D communication range. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
