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.
Claims21
A method for group-based reactive service discovery, the method comprising:
- receiving a first short publishing beacon at a first station belonging to a first group of stations;
- listening for a join request from a second station during a join request interval following receipt of the first short publishing beacon, the second station not belonging to the first group of stations when the first short publishing beacon is received;
- and
- wherein the first station is configured to communicate with the other stations of the first group of stations using single-hop communications.
A wireless communication device for group-based reactive service discovery, the wireless communication device comprising:
- a IEEE 802.11 compatible wireless transceiver configured
- to receive a first short publishing beacon of a first group of stations, wherein the first group of stations includes the wireless communication device, and
- to listen for a join request from a second station during a join request interval following the receiving of the first short publishing beacon, the second station not belonging to the first group of stations when the first short publishing beacon is received;
A wireless communication device configured for group-based reactive service discovery, the wireless communication device comprising:
- a processor;
- memory coupled to the processor;
- an antenna;
- and
- an IEEE 802.11 compatible wireless transceiver configured
- to provide wireless communications of information to be store into and retrieved from the memory using the antenna;
- to wake from a sleep mode at or near an immediately up-chain beacon time,
- to receive a first short publishing beacon from an immediately up-chain station, wherein the immediately up-chain station and the wireless communication module belong to a first group of stations,
- to enter the sleep mode after receiving the first short publishing beacon;
- to wake from the sleep mode at or near an immediately down-chain beacon time,
- to receive a third short publishing beacon from an immediately down-chain device;
- and
- to enter the sleep mode after receiving the third short publishing beacon.
