    Abstract: Location related information is collected for a network of communication devices that each is operable in a coordinating mode and in a non-coordinating mode. While in the coordinating mode, each communication device collects and stores location determining information (410, 420). Using the location determining information collected by one or more of the communication devices over multiple instances of operation in the coordinating mode, location information is calculated or updated for selected devices within the network (510, 520, 530, 540). In one embodiment, each device operates to mediate communication activities among others devices of the network while in the coordinating mode.

    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: 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.

    Abstract: A method, wireless controller, and information processing system are provided to dynamically allocate spectrum sensing resources. A first input (804) including available sensing session time for performing spectrum sensing with respect to one or more primary systems (102) is received. A second input (806) including a set of communication channels to be monitored in the spectrum sensing session is received. A third input (808) including detection constraints associated with a plurality of available sensing nodes (114) in a secondary network (104) for performing the spectrum sensing is received. Spectrum sensing resources are dynamically allocated (814) among a set of the plurality of available sensing nodes (114) based on the first (804), second (806), and third inputs (808).

    Abstract: A method and system is provided for determining a location for each of a plurality of units, which is selected from one of multiple sets of locations, which are each estimated based upon different initial location estimates. The selected set of locations includes the set which has the minimum error value, where the error value is based on the aggregate of the differences between the range determined from the estimated locations and the measured range. By using different sets of initial location estimates, there is a greater chance that at least one of the sets of initial location estimates will avoid any local minimums and produce a more accurate estimate of unit locations.

    Abstract: The present invention provides a multimode receiver design for mitigation of frequency offset by selective demodulation of an input modulated signal. The receiver (103) comprises a plurality of demodulators (207). Each of the plurality of demodulators (207) has the same functionality but different receiver sensitivity versus frequency-offset mitigation characteristics. Each of these demodulators incorporates a different demodulation technique. A suitable demodulator is selected to demodulate the received signal. The choice of a suitable demodulator is based on the value of the frequency offset (305, 307).
