| 20090010258 | PACKET PRIORITIZATION IN AD HOC NETWORKS - A wireless communication device operable as a node in an ad hoc network ( | 01-08-2009 |
| 20090022090 | SWITCHING ALLOCATION IN AD HOC NETWORK - A method in a wireless communication device ( | 01-22-2009 |
| 20090061889 | METHOD AND DEVICE FOR FREQUENCY ALLOCATION MANAGEMENT IN AN AD HOC NETWORK - Disclosed is a method for frequency allocation management in an ad hoc network that includes a plurality of cognitive radio devices. The method comprises dynamically selecting a cognitive radio device from the plurality of cognitive radio devices based on a communication device criteria, assigning a role of a central resource manager to the selected cognitive radio device to assume responsibility of allocating frequency to other of the cognitive radio devices within the ad hoc network, selecting a backup cognitive radio device from other one of the cognitive radio devices within the ad hoc network by the central resource manager, and transferring the role of the central resource manager to the backup cognitive radio based on a second criteria by the central resource manager. | 03-05-2009 |
| 20090141662 | METHOD AND APPARATUS FOR OPERATING A NODE WITHIN A MOBILE AD HOC COGNITIVE RADIO NETWORK - A method and apparatus for operation of a node within a mobile ad hoc cognitive radio network is provided. The method includes sensing at least one assigned communications channel. Sensing at least one assigned communications channel includes measuring a value of at least one parameter corresponding to the communications channel. The method further includes comparing the measured value of the at least one parameter with a set of stored values of the at least one parameter to determine a change in the measured values. Finally a sleep mode of the node is activated for a time period, wherein the time period is determined using the change in the measured values. | 06-04-2009 |
| 20090245119 | COMMUNICATIONS SYSTEM FOR EXCHANGING SPECTRUM SENSING MEASUREMENTS THROUGH A DROP BOX AND METHOD OF USING SAME - A communications system and method for exchanging spectrum usage information through a drop box ( | 10-01-2009 |
| 20100027517 | METHOD FOR MULTI-BAND COMMUNICATION ROUTING WITHIN A WIRELESS COMMUNICATION SYSTEM - A method of operation of a node for multi-band communication routing within a wireless communication system comprises communicating a communication session on a default route within an identified quality of service objective on a first frequency band; broadcasting, on a second frequency band, one or more route discovery messages at each of a plurality of sets of transmission variables; storing one or more alternate route table entries in a route table, wherein each of the one or more alternate route table entries are indexed by each of the plurality of sets of transmission variables that are at least within the quality of service objective; selecting a stored alternate route that is at least within the quality of service objective of the communication session on the second frequency band; and switching the communication session to operate using the transmission variables related to the selected alternate route. | 02-04-2010 |
