  • Publication number: 20090262642
    Abstract: 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.

  • Publication number: 20090003243
    Abstract: 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.

  • Patent number: 7068630
    Abstract: In a packet communication system having a plurality of independently operating nodes which have limited available communication time and which are capable of monitoring busy time and idle time in cyclical epochs, a method is provided for measuring and computing a load on the communication time of the local node in communication with a plurality of other nodes wherein the period of load measurement is synchronized to the communication epoch and the load attributed by the local node is subtracted to assure that the measurement is accurate.

  • Patent number: 5453977
    Abstract: In a mesh communication network, new network nodes acquire information about nearby nodes to which they may communicate through a third-party query whereby an established node with which a new node can communicate is queried to provide a list of nodes in the vicinity of the new nodes with which the new node is likely to be able to communicate. The new node uses this list in attempting to establish communication links and then repeats the third-party query for each node in the list to which it can communicate.
