摘要： 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. In the event none of the neighboring nodes have an unchanged reboot counter, requests may be made for the reboot counters of other nodes, which may be compared to the corresponding stored reboot counters, until the rebooting node discovers a node which has not recently rebooted according to the reboot counter, and may then download routing information from that node. 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.
摘要翻译：一种更新网络中的路由信息的方法，其中网络中的其他节点的重新启动信息用于确定给定节点是否具有最近的路由更新。如果重新启动信息指示给定节点最近没有重新启动，则使用来自给定节点的路由信息来更新比较节点的路由信息。重新启动信息可以是重新启动计数器，其响应于节点经历重新启动过程而由节点增加。当一个节点重新启动时，它可能会向邻居节点请求重启计数器。将接收到的重启计数器与至少一个节点的存储重启计数器进行比较。重新引导节点可以选择从没有从存储的重新引导计数器改变重新启动计数器的节点接收路由信息。在没有任何相邻节点具有不变的重启计数器的情况下，可以对其他节点的重启计数器进行请求，其可以与相应的存储的重启计数器进行比较，直到重启节点发现最近没有重启的节点为止到重启计数器，然后可以从该节点下载路由信息。在电力恢复到公用事业网络中的节点之后，该节点使用其一个或多个相邻节点作为代理来将消息路由到公用事业的中央控制设施。

摘要： A method and system for providing a network protocol for utility services are disclosed are disclosed. In one embodiment, a computer-implemented method comprises discovering a utility network, wherein a constant powered meter sends network discovery messages to find the utility network. Neighboring meters are discovered, wherein the constant powered meter sends hello messages periodically. The constant powered meter is registered with the utility network. Further, the battery powered meter finds and associates itself with a constant powered meter. The constant powered meter also registers its associate battery powered meter with the utility network. The constant powered meter sends a node registration message to the gateway of the utility network. The constant powered meter can sense outage problems with the gateway and the neighbors of its network, and search and migrate to an alternate network.
