Method for estimating the location of a wireless device in a communication network
First Claim
1. A method of estimating a location of a blindfolded node in a wireless network having a plurality of reference nodes, the method comprising:
- combining the plurality of reference nodes into reference pairs;
obtaining a plurality of probable regions for the blindfolded node based on the reference pairs;
overlapping the plurality of probable regions; and
estimating the location of the blindfolded node as a geometric center of the overlapped plurality of probable regions.

Abstract
A method for estimating the location of a blindfolded node (235) in a wireless network having reference nodes (225, 230) is provided. The reference nodes (225, 230) are combined into pairs (301) and each pair is checked to determine if the reference nodes are within each other'"'"'s communication rage (304). A plurality of probable regions (315) for the blindfolded node are obtained (313, 315). These probable regions are overlapped (320), and the blindfolded node'"'"'s estimated location is estimated to be the geometric center of the overlapped regions (325).

9. A method of determining a location of a blindfolded node using a plurality of reference nodes in a wireless network, the method comprising:
-
determining a plurality of reference node proximities for each reference node, the plurality of reference node proximities comprising a proximity of the reference node to each other reference node in the plurality of reference nodes based on a predetermined parameter;
determining a blindfolded node proximity between each reference node and the blindfolded node based on the predetermined parameter;
performing a comparison between the blindfolded node proximity and the plurality of reference nodes for each reference node to obtain a plurality of probable locations of the blindfolded node; and
identifying the location of the blindfolded node using the plurality of probable locations. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method of locating a blindfolded node in a wireless network, the method comprising:
-
providing a single reference node within the wireless network; and
determining a probable location of the blindfolded node to be within a geometric region, the geometric region being determined by the location of the single reference node and the maximum communication range of the single reference node. - View Dependent Claims (19, 20)
