    摘要: A system (400), apparatus (300), and method (100) are provided to synchronize distributed (otherwise uncoordinated) networks (400) of independent nodes (401i). Such synchronization can be used in a number of different ways. In the context of cognitive radios, such synchronization can be used to synchronize quiet periods. Quiet periods are times when all cognitive radios (that are otherwise uncoordinated) become quiet so that incumbent users can be detected reliably. The technique of the present invention converges quickly and scales well.

    摘要: In a distributed-control cognitive radio network, each secondary user (200) in a network broadcasts parameters (125) that indicate the minimum quiet-period sensing demand for regular quiet-periods that the device requires for reliable detection of a primary user (290). Each device (200) in the network adjusts its quiet-period sensing rate to accommodate the highest minimum sensing demand (155, 160), thereby providing optimal efficiency relative to quiet-period support while assuring that all devices (200) in the network are provided at least their minimum quiet-period sensing demand (150). Both the interval between regular quiet-periods and the duration of these quiet-periods are negotiated among the devices on the network (155). A quiet-period index (140) is used to synchronize all of the devices to a common time base. Techniques are also provided for efficient coordination of on-demand quiet-period requests, and for supporting different quiet-period schedules for multiple classes of primary users.
