  • Publication number: 20150223047
    Abstract: A method includes transmitting, from an electronic device in a neighbor awareness network (NAN) via a first wireless protocol, a wake up message indicating discovery information associated with a second wireless protocol. The method further includes communicating information via the NAN using the second wireless protocol after transmitting the wake up message.

  • Patent number: 8948744
    Abstract: A spatio-temporal random voting scheme is provided that incorporates location distribution, spatial randomness, and temporal randomness in the collection of information from a plurality of sensing devices within the cognitive network. The region is divided into a plurality of sectors, where each sector is a portion of the region. A subset of sectors is selected from the plurality of sectors in the region to provide spatial randomness. A device is randomly selected from each sector in the subset of sectors to provide additional spatial randomness to the information collection process. Temporal randomness may be introduced by randomly selecting a timeslot within a sensing window period in which devices are to scan a frequency spectrum band to determine if a signal energy above a threshold is detected. Sensing reports are then collected from the selected sensing devices and used to determine whether the frequency spectrum band is available or in use.

  • Publication number: 20140199070
    Abstract: In a method of scheduling frames, a first channel of a plurality of channels is selected for a first frame. The first frame is sent across a media-independent interface to a physical-layer device for transmission on the first channel. A data rate of the media-independent interface is greater than a data rate of the physical-layer device for the first channel. After the first frame is sent across the media-independent interface, subsequent sending of frames for the first channel across the media-independent interface is disabled for a period of time that is based at least in part on rate adaption from the data rate of the media-independent interface to the data rate of the physical-layer device for the first channel.
