Abstract

In a wireless communication system comprising a plurality of mesh points (MPs), a method for determining a level of involvement of MPs within the system includes a first MP transmitting a network status request signal to a second MP. The second MP responds to the first MP with network status information. The first MP receives the network status information from the second MP, and determines a level of involvement in the wireless system based on the network status information.

Claims

1. A method implemented in a mesh point (MP) of a mesh network for use in wireless communication, the method comprising:

the MP receiving information about a status of the mesh network from a neighbor mesh point (MP), wherein the information about the status of the mesh network includes an identification of the neighbor MP, a number of available MPs comprising the mesh network, and a level of involvement of the neighbor MP in the mesh network including at least one of bandwidth availability information, external network availability information, or an indication of an availability to transmit to other MPs of the mesh network; and

the MP setting a level of involvement of the MP in the mesh network based on the information about the status of the mesh network.

2. The method of claim 1, wherein the information about the status of the mesh network indicates that the neighbor MP does not provide routing to the other MPs of the mesh network.

3. The method of claim 1, wherein the information about the status of the mesh network indicates that the neighbor MP provides limited routing.

4. The method of claim 1, wherein the information about the status of the mesh network indicates that the neighbor MP provides emergency routing.

5. The method of claim 1, wherein the information about the status of the mesh network indicates that the neighbor MP does not transmit path selection protocol messages and does not respond to path selection protocol messages.

6. A mesh point (MP) configured to operate in a mesh network, the MP comprising:

a receiver configured to receive information about a status of the mesh network from a neighbor MP, wherein the information about the status of the mesh network includes a neighbor MP identification, a number of available MPs comprising the mesh network, and a level of involvement of the neighbor MP in the mesh network including at least one of bandwidth availability information, external network availability information, or an indication of an availability to transmit to other MPs of the mesh network; and

a processor configured to set a level of involvement of the MP in the mesh network based on the information about the status of the mesh network.

7. The MP of claim 6, wherein the information about the status of the mesh network indicates that the neighbor MP does not provide routing to the other MPs of the mesh network.

8. The MP of claim 6, wherein the information about the status of the mesh network indicates that the neighbor MP provides limited routing.

9. The MP of claim 6, wherein the information about the status of the mesh network indicates that the neighbor MP provides emergency routing.

10. The MP of claim 6, wherein the information about the status of the mesh network indicates that the neighbor MP does not transmit path selection protocol messages and does not respond to path selection protocol messages.
