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).

Abstract: A method and location determination module is provided for determining a location of one of a plurality of units (16A, 16B, 16C, 12, 14) using neighbor lists (212). Each unit is communicatively coupled to at least some of the other plurality of units (16A, 16B, 16C, 12, 14), where at least some of the plurality of units (16A, 16B, 16C, 12, 14) are reference units, whose locations are known. The units communicate with other (16A, 16B, 16C, 12, 14) nearby units within communication range, to establish neighbor lists (212). A unit to be located then identifies an aggregate value corresponding to the number of occurrences of the reference units in the neighbor list (212) of the unit to be located and the neighbor lists (212) of each of a group of associated units. The location of the unit to be located is then determined, based upon the known locations of the reference units and the number of identified occurrences of the reference units in the corresponding neighbor lists (212).

Abstract: A location technique is utilized where channel-model parameters are originally estimated prior to location taking place. Location then takes place using a first set of known-located nodes, and the channel-model parameters are updated based on the distances resulting from the location estimate. Once the channel-model parameters have been updated, location again takes place using a second set of known-located nodes, node distances are calculated based on the produced locations and the channel-model parameters are again updated. This process continues until no significant change is observed between the previous and the newly estimated location, or until a maximum number of iterations is reached.

Abstract translation: 在位置发生之前，最初估计信道模型参数的位置技术被使用。 然后使用第一组已知定位的节点进行位置，并且基于由位置估计导致的距离来更新频道模型参数。 一旦信道模型参数被更新，再次使用第二组已知定位的节点进行位置，则基于所产生的位置来计算节点距离，并再次更新信道模型参数。 该过程继续进行，直到在先前和新估计的位置之间没有观察到显着变化，或直到达到最大次数。

Abstract: A method and apparatus for locating a remote unit (or node) is provided herein. During operation, location-finding equipment (106) will determine a gross location of non-located nodes (104) by determining distances of the nodes (104) to reference nodes (105). Additionally an error estimate in the location for each node is determined. A first subset of nodes having relatively lower error estimates are "promoted" to reference nodes, and a second subset of nodes having higher error estimates are again located based on a distance to the newly-promoted reference nodes.
