Determination of link qualities between an access point and a plurality of clients
First Claim
1. A method of determining link qualities of a plurality of links between an access point and a plurality of client devices, comprising:
- detecting all client devices associated with the access point, wherein detecting a client device comprises the access point performing a request and response exchange with the client device;
generating a list of the associated client devices;
the access point transmitting keep alive packets to each of the associated client devices according to the list;
the access point counting responses to the keep alive packets from each of the client devices; and
the access point estimating a link quality of a wireless link between the access point and each client device based on the counted responses;
whereinthe estimates of link quality are based on a packet success probability as determined by a percentage of keep alive packets sent to each client device that result in a response received by the access point from the client device.

Abstract
An apparatus and method of determining link qualities of a plurality of links between an access point and a plurality of client devices is disclosed. The method includes detecting all client devices associated with the access point. A list of the associated client devices is generated. The access point transmits keep alive packets according to the list. The access point counts responds to the keep alive packets from each of the client devices. The access point estimates a link quality between the access point and each client device based on the counted responses. An apparatus and method of determining link qualities of a plurality of links between an access node of a wireless mesh network and a plurality of client devices is also disclosed. The method includes detecting all client devices associated with the access node. A list of the associated client devices is generated. The access node transmits keep alive packets to each of the associated client devices according to the list. The access point counts responds to the keep alive packets from each of the client devices. The access point estimates a link quality between the access point and each client device based on the counted responses.

19. An access point including processor and memory, the access point operative to:
-
detect all client devices associated with the access point, wherein detecting a client device comprises the access point performing a request and response exchange with the client device; generate a list of the associated client devices; transmit keep alive packets to each of the associated client devices according to the list; count responses to the keep alive packets from each of the client devices; and estimate a link quality of a wireless link between the access point and each client device based on the counted responses;
wherein the estimates of link quality are based on a packet success probability as determined by a percentage of keep alive packets sent to each client device that result in a response received by the access point from the client device.
