    摘要: The present invention is a system (1200), base station (1100)/customer premise equipment (1150) apparatus, and method (400 450) for a two-stage quiet-period management mechanism that provides the required protection to incumbents (primary spectrum users) while supporting the desired QoS of secondary users participating in a cognitive radio network. In the first stage, a simple fast sensing (301) is done (e.g., energy detection) by all devices in the network. Depending on the result of the fast sensing, the second and possibly longer stage, herein termed fine sensing (302), is performed.

    摘要: A medium access control (MAC) duty cycling is carried out in a body area network (BAN). The duty cycling includes sending a wake-up (WUP) message from a sender node to one or more target receiver nodes when a wireless medium of the BAN is free (S510); determining if at least one target receiver node responded with a READY message during a sniff time interval of the sender node (S520); determining if a number of WUP messages transmitted by the sender node exceeds a predefined threshold when the READY message was not received (S540); and setting the sender node to operate in a TURN mode when the number of WUP messages exceeded the predefined threshold (S550).

    摘要: The system (500), apparatus (400), and method of the present invention provide three architectures for logically organizing multiple channels: a parallel multi-channel superframe (PMS) (100), a sequential multi-channel superframe (SMS) (200), and a non-overlapping multi-channel superframe (NMS) (300). Each of these architectures arises from different trade-offs and is applicable to any multi-channel MAC protocol that is based on the concept of a superframe, e.g., IEEE 802.11 superframe.

    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.
