Abstract

Systems, methods, and devices are disclosed for managing possible mergers between neighbor-aware or social Wi-Fi network clusters in a wireless network. In one aspect, a method includes identifying, at a device of a group supported by a first wireless network cluster, a neighboring wireless network cluster. The method further includes joining the neighboring wireless network cluster while remaining in the first wireless network cluster. The method further includes determining whether to stay with either the neighboring wireless network cluster or the first wireless network cluster based on information from the neighboring wireless network cluster or the first wireless network cluster. The method further includes announcing a decision to leave the first wireless network cluster or the neighboring wireless network cluster.

3. The method of claim 2, wherein advertising the countdown timer comprises advertising the countdown timer during one or more of a discovery window and a data link time block of the first wireless network cluster or the neighboring wireless network cluster.

4. The method of claim 2, further comprising selectively merging the device with the first wireless network cluster or the neighboring wireless network cluster and leaving the other wireless network cluster at an end of the countdown timer.

5. The method of claim 1, wherein the information comprises one or more of a cluster age, a cluster size, a number of available services in the first wireless network cluster or the neighboring wireless network cluster, and a timing schedule of the first wireless network cluster or the neighboring wireless network cluster.

6. The method of claim 1, wherein joining the neighboring wireless network cluster is based on a cluster grade of the neighboring wireless network cluster.

7. The method of claim 1, further comprising merging the device from the first wireless network cluster to the neighboring wireless network cluster in response to an expiry of a validity time duration of the group supported by the first wireless network cluster.

8. The method of claim 7, wherein the validity time duration is a property of a neighbor aware network (NAN) data link (NDL) logical channel or the group supported by the first wireless network cluster.

9. The method of claim 7, wherein the validity time duration comprises a time period after which the group supported by the first wireless network cluster ceases to exist unless a provider in the group supported by the first wireless network cluster extends the validity time duration.

10. A wireless communication device in a group supported by a first wireless network cluster, comprising:

a processor configured to;

identify a neighboring wireless network cluster;

join the neighboring wireless network cluster while remaining in the first wireless network cluster for a time period;
