In a mesh network having a plurality of wireless nodes, including a first, second, third and fourth node, wherein each node includes a routing table, a method of route discovery. A first route request message is broadcasted from the first node and received at the second and third nodes. In the second node, a link quality metric is calculated as a function of link quality of the link to the first node and as a function of capacity in the routing table of the second node. In the third node, a link quality metric is calculated as a function of link quality of the link to the first node and as a function of capacity in the routing table of the third node. A second route request message is broadcasted from the second node and received by the fourth node, wherein the second route request message includes the link quality metric calculated by the second node. A third route request message is broadcasted from the third node and received by the fourth node, wherein the third route request message includes the link quality metric calculated by the third node. A route path is selected as a function of the link quality metric calculated by the second node and the link quality metric calculated by the third node. |
