Abstract:
Apparatus and methods for, among other things, a grouped based reactive service discovery protocol are discussed. In an example, a method can include broadcasting a first group beacon at a group interval using a first station belonging to a first group of stations and broadcasting a service request to the second group during a query interval of the second group. In an example, the first group beacon can include a service update alert configured to alert other members of the first group of an anticipated service request and response event to learn services available from a second group.
Abstract:
Embodiments of a system and method for secure discovery and identification of devices via a wireless network are generally described herein. In some embodiments a wireless device may transmit an anonymous ephemeral identifier that may be utilized by a second device to determine, by accessing a provider or social network, whether the private identity masked by the ephemeral identifier is known to the user of the second device. In some embodiments a provider may receive user or device registrations; maintain a record of private identifiers, ephemeral identifiers, and known user data for a plurality of users; and access one or more social networks to acquire known user data. The ephemeral identifiers may be periodically updated by the provider. In some embodiments a discovery module in a plurality of devices may automatically establish a communication connection between devices in response to a previously established relationship between users of the respective devices.
Abstract:
Logic may decide which service advertisement information to transmit in a service advertisement frame based on link margin information of each service advertisement received. Logic may filter the service advertisement information to avoid advertising service information for service providers that cannot be reached. A first station may receive a service advertisement from a second station and determine whether to include the service advertisement with a transmission of the first station's service advertisement based upon perceived proximity of the second station. A station may generate a Leaving Message if a user terminates service advertisements of the station or the station appears to be moving away from a service advertisement group. In response to receiving a Leaving Message from a neighboring station, a station may remove the neighboring station from a list of service providers maintained by the station.
Abstract:
Apparatus and methods for, among other things, a hybrid service discovery protocol are discussed. In an example, a method for hybrid service discovery can include transmitting a first one or more reactive publishing beacons for a first group of stations, counting a quantity of service requests during query windows following the reactive group beacon transmissions, and publishing a first proactive publishing beacon for the first group of stations if the quantity of service requests meet or exceed a proactive service discovery threshold.
Abstract:
Apparatus and methods for, among other things, a group-based reactive service discovery protocol are discussed. In an example, a method can include broadcasting a first group beacon at a group interval using a first station belonging to a first group of stations and broadcasting a service request to the second group during a query interval of the second group. In an example, the first group beacon can include a service update alert configured to alert other members of the first group of an anticipated service request and response event to learn services available from a second group. In an example, the service update alert can include a beginning time for the anticipated service request and response event.
