Abstract

A communication device configured to form a cluster with one or more other communication devices in its vicinity, monitor the presence, in the cluster, of those other communication devices and provide information about the presence, in the cluster, of the other communication devices to another device.

First claim

What is claimed is:

1. A communication device comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, causes the communication device to:
form a cluster with other communication devices based on a proximity of the other communication devices to the communication device;
establish a mesh network with at least one of the other communication devices;
monitor a presence, in the cluster, of the other communication devices based at least in part on communications received via the mesh network; and
communicate information about the presence, in the cluster, of the other communication devices to a remote device that is not part of the cluster.

2. The communication device of claim 1 , wherein the other communication devices include at least one device that is not configured to communicate via the mesh network.

3. The communication device of claim 1 , wherein execution of the instructions to monitor the presence of the other communication devices causes the communication device to:
transmit query messages to the other communication devices; and
listen for responses from the other communication devices.

4. The communication device of claim 1 , wherein execution of the instructions to monitor the presence of the other communication devices causes the communication device to:
receive periodic presence updates from the other communication devices; and
determine that a particular communication device has left the cluster if no presence update is received from the particular communication device.

5. The communication device of claim 1 , wherein execution of the instructions further causes the communication device to:
configure an identity associated with one or more of the other communication devices; and
communicate the identity to the remote device.

6. The communication device of claim 1 , wherein execution of the instructions further causes the communication device to:
receive, from one or more of the other communication devices in the cluster, information relevant to a condition of the cluster; and
communicate the information to the remote device.

7. The communication device of claim 6 , wherein the information is relevant to the cluster as a whole.

8. The communication device of claim 6 , wherein the information includes different types of information from different ones of the other communication devices.

9. A communication device comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, causes the communication device to:
monitor a presence of the communication device in a cluster with other communication devices based at least in part on communications received via a mesh network formed with at least one of the other communication devices; and
communicate information about the presence of the communication device in the cluster to a remote device that is not part of the cluster.

10. The communication device of claim 9 , wherein execution of the instructions to communicate information about the presence of the communication device further causes the communication device to:
transmit an alert to the remote device when the communication device joins or leaves the cluster.

11. The communication device of claim 9 , wherein execution of the instructions further causes the communication device to:
identify the cluster based at least in part on communications received via the mesh network; and
select a network key to be used for communicating with the other communication devices based on the identified cluster.

12. The communication device of claim 9 , wherein execution of the instructions further causes the communication device to:
determine a location of the communication device; and
communicate information about the location to the remote device.

13. The communication device of claim 9 , wherein the communication device uses a different communications protocol to communicate with the remote device than with the other communication devices in the cluster.

14. A method for tracking a plurality of communication devices, the method being performed by a first communication device of the plurality of communication devices and comprising:
forming a cluster with others of the plurality of communication devices in its vicinity by based at least in part on a proximity of the other communication devices to the first communication device;
establishing a mesh network with at least one of the other communication devices;
monitoring a presence, in the cluster, of the other communication devices based at least in part on communications received via the mesh network; and
communicating information about the presence of the other communication devices in the cluster to a remote device that is not part of the cluster.

15. The method of claim 14 , wherein the information about the presence of the other communication devices includes a notification that a particular communication device is leaving or joining the cluster.

16. The method of claim 14 , further comprising:
communicating information about the first communication device leaving or joining the cluster.

17. The method of claim 14 , further comprising:
establishing a network with communication devices belonging to one or more other clusters.

18. The method of claim 17 , further comprising:
determining a status of the one or more other clusters from the remote device.

19. The method of claim 18 , wherein the remote device forms part of the network with the communication devices belonging to the one or more other clusters.
