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: An architecture for over the air management of software on a wireless device includes a software architecture supporting software patches, including secure downloading of software from a data network and robust installation of the same on the wireless device. Using this architecture, a network operator can notify a mobile device user about the software upgrade and send the upgrade to the mobile device over the air. Remote management of DSP software on mobile phones in GSM or GPRS networks uses an efficient installation algorithm with an error recovery mechanism. A digital signature is used for checking authenticity and integrity of the downloaded DSP software patch.
