摘要： One embodiment of the present invention sets forth a technique for a node within a network to adjust one or more routing parameters based on certain network parameters. A node monitors certain network metrics such as the mean time between routing drops. In response to changes in these network parameters, the node changes certain routing parameters, such as the holddown time. The node may store network metrics and associated routing parameters that result in preferred network operating conditions. The node may pre-load these beneficial settings upon the occurrence of a particular condition such as a system reset of the node. Moreover, a node may share these beneficial settings with neighboring nodes on the same network. One advantage of this approach is that cost savings are achieved when a node within a network may be installed without preconfiguring the node with specific routing parameters.

摘要： In an embodiment of a wireless network, when a node joins the network and receives a routing advertisement, such a node transmits the routing advertisement to all its neighbors. The node then receives transmission from the neighboring nodes indicating interest in joining the advertised network. If more than a threshold number of neighboring nodes are interested in the advertised route, the newly joining node inserts the route advertisement in a beacon transmission. If there is not a threshold level of interest, the node unicasts only to the neighbors who indicated interest in the advertised network. In an embodiment, the node repeats the above steps on a predetermined time basis (e.g., one per day) in order to determine interest in the advertised route that may have newly arisen.

摘要： A node within a wireless mesh network performs a path analysis on an advertised path to an access point that has a cost value less than the cost value of the current primary path to the access point. Depending on the cost value difference between the respective cost values of the advertised path and the current primary path, the node may perform a different type of path analysis. Based on the result of that path analysis, the node may change paths to the access point and use the advertised path as the primary path. Further, the node maintains a secondary path so that, in the event that the primary path fails, the node can default to using the secondary path.

摘要： After power is restored to a node in a utility network, that node employs one or more of its neighboring nodes as proxies to route a message to a central control facility of the utility. The message contains information about the restored node, and possibly one or more of its neighbor nodes. This information may include reboot counters, the amount of time that the node was down, momentary outages or power fluctuations, and/or the time of power restoration. The node that creates and initially sends the message can be the restored node itself, or another node that recognizes when a restored node has recently come back online.

摘要： Methods and systems for providing a network and routing protocol for utility services are disclosed. A method includes discovering a utility network. Neighboring nodes are discovered and the node listens for advertised routes for networks from the neighbors. The node is then registered with one or more utility networks, receiving a unique address for each network registration. Each upstream node can independently make forwarding decisions on both upstream and downstream packets, i.e., choose the next hop according to the best information available to it. The node can sense transient link problems, outage problems and traffic characteristics. Information is used to find the best route out of and within each network. Each network node maintains multi-egress, multi-ingress network routing options both for itself and the node(s) associated with it. The node is capable of several route maintenance functions utilizing the basic routing protocol and algorithms.

摘要： The functionality of communications standards and protocols that are application-layer specific are overlaid on an IP-based infrastructure, by employing an IP DNS server as the registration host for IP and other communications standards based and protocol based communications. Communication can occur at either the IP layer or the communications standards or protocol application layer. At the IP layer, a host application can interrogate network nodes. To extend this service to other communications standards or protocol communications, device registration and resolve services are implemented on the DNS server. Similar to the manner in which an IP-based service uses a native, IP-based DNS resolve request, a host can utilize a resolution request against the communications standards and protocol-enabled DNS server for standards and protocol application-layer interrogation of endpoints.

摘要： One embodiment of the present invention implements a FHSS system using single transmitter/multiple receiver transceivers. Such transceivers are configured to receive multiple FHSS channels (e.g., five channels) but only transmit on one channel. In an embodiment, one channel is dedicated to high priority traffic and the other four channels are dedicated to standard traffic. In receiving a high priority message, the transceiver is configured to address the high priority traffic first. For example, because the single transmitter/multiple receiver transceivers only has one transmitter, such transceiver may immediately dedicate it transmitting resources to addressing the received high priority data. Other embodiments are disclosed that implement multiple priorities among a plurality of communication channels.

摘要： Techniques are disclosed by which RF mesh networks can identify utility distribution topologies by using power line communication combined with wireless networking to identify the mapping of transformers and other distribution equipment at a back office system server. At a specified time, an item of distribution equipment signals a unique identifier by introducing a phase shift in the electric power being delivered by that equipment. A meter node detects and decodes these temporal shifts to obtain an identifier of equipment supplying the power to it. Upon ascertaining this identification, the meter node sends an acknowledgment to thereby register with that equipment. The association of the particular customer's premises with the equipment is also sent to a back office system, to enable a map of the correspondence between meter and the equipment to be generated.
