Abstract

An apparatus and method of an access point suppressing probe responses is disclosed. The method includes the access point receiving a probe request from a client device. The access point determines a quality of a link between the access point and the client device based on the probe request, and the access point communicates to other access points, a client identifier and the quality of the link between the access point and the client device.

Claims

1. A method of an access point suppressing probe responses, comprising:

the access point receiving a probe request from a client device;

the access point determining a quality of a link between the access point and the client device based on the probe request;

the access point communicating to other access points, a client identifier and the quality of the link between the access point and the client device.

2. The method of claim 1, wherein the access point communicates the client identifier and the quality of the link between the access point and the client device, if the quality of the link is above a threshold.

3. The method of claim 1, wherein the access point communicates to the other access points by broadcasting to the other access points.

4. The method of claim 1, further comprising:

the access point determining link qualities between the access point and a plurality of client devices;

the access point broadcasting to other access points, client device identifiers for each of the client devices and corresponding link qualities for each of the client devices, if the corresponding link qualities are above a threshold.

5. The method of claim 1, further comprising:

the access point receiving communication from other access points that include link qualities between each other access point and the client device;

the access point responding to the probe request with a probe response based on a qualitative comparison between of the quality of the link between the access point and the client device and the link qualities between the other access points and the client device.

6. The method of claim 1, wherein determining a quality of a link between the access point and the client device based on the probe request comprises measuring received signal strength of the probe request.

7. The method of claim 1, wherein determining a quality of a link between the access point and the client device is additionally influenced by a wireless network access point quality parameter.

8. The method of claim 7, wherein the network quality parameter comprises at least one of an access point throughput, an access point latency, an access point backhaul bandwidth.

9. A method of determining which of a plurality of access points has a highest quality link with a client device, comprising:

at least one of the plurality of access points receiving a probe request from the client device;

each access point that receives the probe request, estimating a link quality between the access point and the client device;

each access point that receives the probe request, broadcasting to other access points, a client device identifier and the corresponding link quality.

10. The method of claim 9, wherein each access point that receives the probe request, broadcasts the client device identifier and the corresponding link quality if the corresponding link quality is above a threshold.

11. The method of claim 9, wherein the link quality is estimated by a received signal received signal strength at the access point.

12. The method of claim 9, further comprising:

at least one access point receiving a broadcast from an other access point the broadcast including link quality information, and associating with the client device if the link quality between the access point and the client device is better than the link quality of the other access point.

13. A method of an access node within a wireless mesh network suppressing client responses, comprising:

the access node receiving a probe request from a client device;

the access node determining a quality of a link between the access node and the client device based on the probe request;

the access node communicating to other access nodes, a client identifier and the quality of the link between the access node and the client device.

14. The method of claim 13, wherein determining a quality of a link between the access point and the client device based on the probe request comprises measuring received signal strength of the probe request.

15. The method of claim 13, further comprising the access node communicating to other access nodes, network quality parameters of the access node.

16. The method of claim 15, wherein the network quality parameter of the access node comprises at least one of a path quality of the access node to a wireless mesh network gateway, a latency of the access node, a backhaul bandwidth of the access node.

17. The method of claim 13, wherein the access point communicates to the other access points by broadcasting to neighboring access points.

18. The method of claim 13, further comprising:

the access node receiving information from other access nodes that includes link qualities between each other access nodes and the client device;

the access node responding to the probe request with a probe response if the quality of the link between the access node and the client device is better than the link qualities between the other access nodes and the client device.

19. The method of claim 13, further comprising:

the access node receiving information from other access nodes that includes wireless mesh network quality parameters of the other access nodes;

the access point responding to the probe request with a probe response if a combination of the quality of the link between the access point and the client device and the network quality parameter of the access node, is better than a combination of the link qualities between the other access points and the client device and the network quality parameters of the other access nodes.

20. The method of claim 19, wherein the network quality parameter of the other access nodes comprises at least one of a path quality of each of the other access nodes to a wireless mesh network gateway, a latency of each of the other access nodes, a backhaul bandwidth of each of other access nodes.
