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.

Network devices in a multi-network wireless mesh network environment identify themselves as members of the network by receiving a broadcast message from a first mesh network device that has joined the wireless mesh network, and identifying that the broadcast transmission has been received such as by actuating a light, playing a sound, or sending an identifying reply message back to a broadcasting mesh network device.

A method of establishing a qualified route in a mesh network includes transmitting a route-discovery request from a source node such that transmitting includes transmitting the route-discovery request from the source node to at least one intermediate node that is a neighbor node to the source node, receiving the route-discovery request from an intermediate node at the destination node, and updating a route-discovery table for the intermediate node such that the route between the source node and the destination node is the only qualified route.

Wireless mesh network nodes in a mesh network are operable to receive a periodic beacon from at least one other mesh network node, where the received beacon comprises received beacon link quality information for the at least one other mesh network node. The nodes are further operable to record the sender identity and link quality of the received periodic beacon, record the received beacon link quality information in the beacon from the wireless mesh network node to the at least one other mesh network node, and retransmit a received periodic beacon to other network nodes, the retransmitted beacon comprising link quality information for beacons received in the wireless mesh network node.
