Abstract: Active proximity based wireless network commissioning is provided. Routers and end devices are placed in a default mode before commissioning such that the devices are communicative but do not transmit join requests. A commissioning device is positioned at a selected location and transmits a wireless beacon request that is received by devices within a limited range. Routers, end devices and coordinator devices within range send response beacons. The response beacons are used by the commissioning device to discover devices and select network parameters for the discovered devices. The commissioning device uses the parameters to prompt the coordinator device to form a network and prompt the qualified device to enter a pending mode and join the network.

Abstract: Methods and system to determine the health of wireless mesh networks are provided. Each radio node of a wireless mesh network transmits Link Quantification Messages (LQMs) interPAN at maximum power to enable adjacent nodes to determine the Received Signal Strength Indication (RSSI) on the wireless link to that radio node. Each radio node also transmits LQMs at successively lower power levels. The adjacent nodes detect a power level at measurable packet error rate to determine a noise floor for the wireless link. An aggregator collects link quantification information from the radio nodes and forms an intercommunication matrix for the wireless network. The RSSI and power level at measurable packet error rate information is used to remove unreliable links from the intercommunication matrix. Nodes are ranked and the reliability and dependability of the nodes is calculated to show the network health.
