third selecting at least one second selected route having a greatest throughput.

11. The method of claim 10 , wherein the at least one second selected route having a greatest throughput is the at least one second selected route having a minimal number of wireless hops.

12. The method of claim 10 , wherein if the at least one third selected route include a default routing path, then the default routing path is determined to be the optimal route.

13. The method of claim 12 , wherein the default routing path is a previously determined optimal route.

14. The method of claim 10 , wherein if the at least one third selected route does not include a default routing path, then selecting the default routing path if the success long ratio of the default routing path is greater than the success long ratios of the third selected routes.

15. The method of claim 10 , wherein if the at least one third selected route does not include a default routing path, then selecting at least one of the third selected routes if the success long ratio of the default routing path is less than the success long ratios of the third selected routes.

16. The method of claim 1 , further comprising determining an optimal wireless route based upon at least one selected route comprises:

third selecting the at least one selected route having a greatest throughput.

17. A method of determining an optimal route based upon path quality of routes to an access node of a wireless mesh network, the method comprising:

receiving routing packets at the access node through at least one wireless route; each routing packet including route information that identifies the wireless route of the routing packet, the route information identifying addresses of all other access nodes of the wireless route between a routing packet originating gateway and the access node;

first selecting at least one wireless route having a greatest throughput; and

determining an optimal wireless route based upon a success ratio of a number of successfully received routing packets of the at least one first selected route.

18. The method of determining an optimal route based of claim 17 , wherein determining an optimal wireless route based upon a success ratio of a number of successfully received routing packets of the first selected routes comprises:

determining the success ratio of a number of successfully received routing packets versus a number of transmitted routing packets over a period of time T 1 , for each first selected route;

second selecting at least one of the first wireless route having a greatest success ratio, and other first selected routes that have success ratios within a predetermined amount of the greatest success ratio; and

determining an optimal wireless route based upon the second selected routes.

19. The method of determining an optimal route of claim 18 , wherein determining an optimal wireless route based upon at least one second selected route comprises:

of the at least one second selected route, receiving routing packets at the access node through at least one second selected route; each routing packet including route information that identifies the wireless route of the routing packet;

determining a success long ratio of a number of successfully received routing packets versus a number of transmitted routing packets over a period of time T 2 , wherein T 2 is substantially greater than T 1 , for each second selected route;

third selecting at least one wireless route having a greatest success long ratio, and other wireless routes that have success long ratios within a second predetermined amount of the greatest success long ratio; and
