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.

The sharing of communication parameter data between modules may be continuous sharing or periodic sharing.

Abstract: Methods and devices are disclosed for dynamically fragmenting packets transmitted in a communications network. Fragments are generated by splitting a packet based on a value of a fragment size parameter. A first fragment is sent to a receiving node. As the sending node, a transmission success parameter is determined that indicates whether the first fragment was successfully received. Based on the value of the transmission success parameter, a link quality parameter value representing a chance a second fragment having the same size as the first fragment will be successfully received by the receiving node is updated. The sending node compares the value of the link quality parameter and a value of a quality threshold parameter and changes the value of the fragment size parameter based on a result of the comparison.

After verifying the authenticity of the update object, the device may copy the update object from the verification portion of the memory to an inactive portion. The inactive portion of the memory can be swapped with an active portion of the memory, such that the inactive portion becomes active.

A connector plate and connector may be used with the antenna having the shunt segment extending out of the plane of the J-Pole antenna. A protective enclosure may be used with the J-Pole antenna and allowing a radiating antenna segment of the J-Pole antenna to extend from the protective enclosure.

Abstract: A method and system for providing a network and routing protocol for utility services are disclosed. In one embodiment, a computer-implemented method comprises discovering a utility network, wherein a utility device (for example, a constant powered meter) sends network discovery messages to find the utility network. Neighboring meters are discovered and the device listens for advertised routes for one or more networks from the neighbors. The device is then registered with one or more utility networks, receiving a unique address for each network registration. Also illustrated in this invention disclosure is how each device of a class of devices (for example, battery powered meter) finds and associates itself with another device (for example, constant powered meter).

The constant powered meter registers itself with the access points and the upstream nodes in the path out of each network.

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.

Abstract: A method of updating routing information in a network where reboot information of other nodes in the network is used to determine whether a given node has recent route updates. If the reboot information indicates the given node has not recently rebooted, then routing information from that given node is used to update the routing information of the comparing node. The reboot information may be a reboot counter which is incremented by a node in response to the node going through a reboot process. When a node reboots, it may request the reboot counter from neighboring nodes. The received reboot counter is compared to the stored reboot counter for at least one node. The rebooting node may choose to receive routing information from a node which has not had its reboot counter changed from the stored reboot counter.

Abstract: Information relating to electrical energy usage for a given account is associated with a time segment that corresponds to a period when the electrical energy was received from an electrical energy distribution system. Electrical energy generation carbon impact information is retrieved for the corresponding time segment specifying when the electrical energy was received from an electrical energy distribution system. A carbon credit is calculated according to the retrieved electrical energy generation carbon impact information, and the retrieved electrical energy usage information associated with the time segment. The calculated carbon credit is then used to update a display of carbon credit related information, such as account balance, rate of carbon credit usage, currently applicable “cost” for carbon credit usage. Notifications can be provided to the consumer if any of this information crosses a threshold value.
