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.

Abstract: Optimized routing in localized dense networks is provided. A packet is received at a first network device in a network. An optimal route for the packet to a neighbor network device in the network is determined using a Source Routing Table (SRT), wherein the SRT includes an optimized routing table and a standard routing table, and wherein the optimized routing table comprises a list of neighbor network devices that the first network device can route to directly and wherein the standard routing table comprises a ZigBee source routing table. The packet is routed using the optimal route.
