    Abstract: A utility network communication device is provided to detect whether anomalous events occur with respect to at least one node in a utility network. The communication device has recorded therein threshold operating information and situational operating information. The threshold operating information includes data indicative of configured acceptable operating parameters of the nodes in the utility network based on respective locational information of the nodes. The situational information includes data indicative of configured operation data expected to be received from nodes in the utility network during a predetermined time period, based on a condition and/or event occurring during the predetermined time period. The communication device receives operation data from nodes in the network, and determines whether the received operation data from a node in the network constitutes an anomalous event based on a comparison of the received operation data with (i) the threshold operating information defined for the node and (ii) the situational information. The communication device outputs notification of any determined anomalous event.

    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.

    Abstract: Communications among multiple nodes via a shared power line medium are carried out by dividing the available frequency spectrum in the shared power line medium into plural non-overlapping channels. A first channel is assigned to a first group of nodes, and a second channel, different from the first channel, is assigned to a second group of nodes. Communications between the first group of nodes can occur simultaneously with communications between the second group of nodes via the shared power line medium. Time slots may be assigned for the communications between the first group of nodes that occurs simultaneously with the communications between the second group of nodes via the shared power line medium. The simultaneous communications between different groups of nodes via a shared power line medium may be implemented using a frequency-hopping spread spectrum technique.

    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.

    Abstract: Systems and methods of optimizing packet flow in a network are disclosed. An internetwork has a first network and plural second networks. A respective packet-in-flight counter is established for each one of the plural second networks and a respective maximum packet-in-flight indication for each one of the plural second networks. The respective packet-in-flight counter for each one of the plural second networks when a request packet is sent from any node in the first network to any node in that one of the plural second networks, or a response packet is received from any node that one of the plural second networks. it is determined whether a second request packet can be sent from any node in the first network to any of the plurality of nodes in one of the plural second networks, based on processing a value of the respective packet-in-flight counter for that one of the plural second networks and a value of the respective maximum packet-in-flight indication for that one of the plural second networks. The respective maximum packet-in-flight indication for each one of the plural second networks is adjusted based on a statistic that is indicative of roundtrip time for request packets sent from any node of the first network to any of the plurality of nodes in that one of the plural second networks.

    Abstract: Systems and methods for detecting device failures in a network having nodes coupled to a central controller, in which a first of the nodes communicates with the central controller via a second of the nodes. When the second node determines that the first node has not transmitted a predetermined number of messages over a predefined number of time periods, the second node provides a failure alert to the central controller. The central controller records a failure alert received from the second node in a log. Based on a set of failure alerts received from a number of nodes recorded in the log, the central controller determines whether the first node has failed.

    Abstract: A wireless network has a server that includes a server controller that controls the receipt and transmission of packets via a server radio. The server controller selects a route to nodes in the wireless network, and provides communication between the wireless network and at least one other network. A plurality of nodes in the wireless network include a node controller that controls the receipt and transmission of packets via a node radio, and selects a route to the server. A route included in a transmitted packet is selected as a preferred route based upon lowest path cost. The lowest path cost is determined on the basis of ambient noise level information associated with links along a given path in the wireless utility network.

    Abstract: Systems and methods of optimizing packet flow in a network are disclosed. An internetwork includes plural networks, each network having plural non-router nodes and at least one router node. The non-router node of a first network can be configured to perform congestion control. The non-router node sends a request packet to a node in a second network. The value of a packet-in-flight counter associated with the network is adjusted when the request packet is sent to the second network node and when a response packet is received from the second network node. The non-router node determines whether another request packet can be sent to another network in the internetwork based on a value of the packet-in-flight counter.

    Abstract: 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.
