1. A client node, comprising:
- a database comprising identification data associated with a plurality of wireless network nodes, the identification data comprising a node identifier and signal strength information associated with the client node and a plurality of second client nodes, the signal strength data having been measured by each of the client node and the plurality of second client nodes; and
processing logic configured to process the identification data to determine a proximity between the client node and an individual second client node of the plurality of second client nodes and to identify the individual second client node of the 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 identification data of the client node and a second identification data of the individual second client node, the matching first and second identification data indicating that a same set of mobile or physical wireless access points measured by the client node and the individual second client node have about equal signal strengths.

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.

11. A method of a client node, comprising:
-
using a database comprising identification data associated with a plurality of wireless network access nodes, the identification data comprising a node identifier and signal strength information associated with the client node and a plurality of second client nodes, the signal strength data 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 node and an individual second client node of the plurality of second client nodes, to process the identification data to determine whether a match between a first identification data of the client node and a second identification data of the individual second client node exists, the matching first and second identification data indicating that a same set of mobile or physical wireless nodes measured by the client node and the individual second client node have about equal signal strength, and to identify the individual second client node of the plurality of second client nodes is within a viable device-to-device (D2D) communication range when the first identification data matches the second identification data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
