Abstract

The invention includes an apparatus and method for determining an optimal route based upon path quality of routes to an access node of a wireless mesh network. The method includes 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. A success ration of a number of successfully received routing packets versus a number of transmitted routing packets is determined over a time Tl, for each wireless route. The wireless route having a greatest success ration is first selected, as are other wireless routes that have success rations within a predetermined amount of greatest success ratio. Of the first selected routes, routing packets are at the access node through the first selected routes. Again, each routing packet including route information that identifies the wireless route of the routing packet.
