Abstract: A wireless device including a selection module configured to select a discovery window from a plurality of discovery windows in which to transmit a discovery frame, and a transmit module configured to transmit on average one discovery frame every predetermined number of discovery windows to reduce probability of collision in response to the one or more wireless devices competing for access to a channel. A discovery window is a time period in which (i) the wireless device and (ii) one or more wireless devices in a network are configured to transmit discovery frames to discover a service in the network prior to associating with each other. The discovery frame includes (i) a publish message to make information about capabilities and services of the wireless device available to other devices or (ii) a subscribe message to gather information about capabilities and services of other devices.

Abstract: A first wireless device including a timing module and a scheduling module. The timing module is configured to determine a timing of a plurality of discovery windows in a network. A discovery window is a time period in which (i) the first wireless device and (ii) one or more second wireless devices in the network are configured to attempt discovery of a service in the network prior to associating with each other. The scheduling module is configured to generate a schedule including a subset of the plurality of discovery windows in which to allow (i) the first wireless device and (ii) the one or more second wireless devices in the network to attempt discovery of the service. The subset includes fewer discovery windows than the plurality of discovery windows.

Abstract: A wireless device including a selection module to select a first discovery window in which to transmit a discovery frame. A transmit module attempts to transmit the discovery frame in the first discovery window. If the discovery frame is not transmitted in the first discovery window, a back off module backs off for one or more discovery windows subsequent to the first discovery window; and the transmit module attempts to transmit the discovery frame in a second discovery window following the backing off, and includes in the discovery frame a count representing a number of the one or more of the plurality of discovery windows to indicate a level of congestion in the network. On receiving the discovery frame, one or more wireless devices adjust respective back off times based on the count to reduce the level of congestion in the network.

Abstract: Systems and techniques relating to management of membership in mobile, wireless ad hoc networks are described. A described technique includes transmitting, by a device that is not a member of an ad hoc network, a request to join the ad hoc network to a given device of the ad hoc network. The method also includes receiving from the given device information including a set of addresses of devices of the ad hoc network that is locally stored at the given device. In addition, the method includes obtaining an address for the requesting device to be different from any address of the received set of addresses.

Abstract: A method of performing service discovery is implemented in a first communication device. In the method, a service discovery request is generated that contains a first identifier associated with a requested service and does not contain a second identifier associated with the requested service. The first communication device is caused to transmit the service discovery request. A service discovery response, received by the first communication device from a second communication device, is processed. The service discovery response contains the second identifier and does not contain the first identifier. At least the second identifier is utilized to determine that the second communication device provides the requested service.

Abstract: The present disclosure describes methods and apparatus for synchronizing devices in a wireless data communication system. A wireless transceiver device of the wireless data communication system transmits a beacon at various intervals that includes both a timestamp indicating a current time and date of the transmitting wireless transceiver device, and a time quality indication indicating a quality of the time source of the transmitting wireless transceiver device. A wireless transceiver device receiving the beacon evaluates the time quality indication included in the beacon. If the time quality indication included in the beacon indicates the transmitting wireless transceiver device has a higher quality time source than the receiving wireless transceiver device, then the receiving wireless transceiver device adjusts its clock based on the timestamp in the beacon, otherwise the receiving wireless transceiver device need not adjust its clock based on the timestamp in the beacon.

Abstract: In a method of performing discovery, at least a plurality of identifiers associated with a plurality of respective communication devices is processed, using a first hash function, to generate a first bit string. The first bit string is indicative of whether each of the plurality of identifiers is included in a group. An indication that a new hash function should be used is detected, and, in response to detecting the indication that a new hash function should be used, at least the plurality of identifiers is processed, using a second hash function different than the first hash function, to generate a second bit string. The second bit string is indicative of whether each of the plurality of identifiers is included in the group.

Abstract: A system including an association module to associate a client station with an access point via a first or a second channel based on a distance of the client station from the access point. The first channel is a television white space channel. The second channel is in 2.4 GHz or 5 GHz band. A channel selection module switches a connection of the client station to the access point between the first and second channels based on the distance of the client station from the access point, a state of the connection of the client station to the access point, and a quality of service requirement of the client station. A routing module routes first and second types of data from the client station to the access point respectively via the first and second channels. A combining module combines data received by the client station via the first and second channels.
