Updating routing and outage information in a communications network
First Claim
1. A method of providing notification of recovery from a power outage in a utility communications network, comprising the following steps:
- upon rebooting of a node in the utility communications network, determining whether the reboot resulted from a loss of power to the node;
discovering neighbor nodes on the communications network with which the node can communicate upon rebooting;
selecting a discovered neighbor node as a proxy for the rebooted node; and
if the reboot is determined to have resulted from a loss of power to the node, automatically transmitting a recovery message from the node to the selected proxy node as the destination of the recovery message, the recovery message indicating that the node has recovered from the loss of power and containing parameter values relating to the state of recovery from the loss of power.

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.
