When a metering coupled to a network loses its primary power source and has a secondary power source, such as a super-capacitor, it recognizes and reports a power outage. In this case, the head end server may verify the power outage report by querying through the downstream nodes coupled to the network about the power outage. When a node loses its primary power source and has no secondary power source, it will fail to make a regularly scheduled report at the appropriate time. Consequently, the head end server verify the power outage by polling downstream nodes coupled to the HAN about the power outage to deduce whether a power outage.

The method of claim 6, wherein the secondary power source is a battery. 9. A system for confirming a power outage report comprising: a first node coupled to a first network, wherein the first node comprises: a meter,an input/output device for receiving data from the meter;one or more processors for: creating a table comprising the data received by the input/output device, the table selected from the group consisting of a history logger table, an event table, a profile table, and a self-read table; andassigning a corresponding sequence number to the table, the sequence number to be incremented when new data is added to the table;a register for storing the one or more tables and corresponding sequence numbers, anda communications module for transmitting the power outage report through the first network to a microportal;one or more other nodes coupled to the first network;the microportal for relaying the power outage report through a second network to a collector;the collector for relaying the power outage report through a third network to a head end server; andthe head end server for: receiving the power outage report;querying the one or more other nodes about a power outage, in response to receiving the power outage report;determining that the power outage report is not false based on the one or more responses from the one or more other nodes in the first network; andtransmitting a request to download any untransmitted information from the first node,wherein the first node receives the request to download the untransmitted information and: accesses any new data in the table;creates a report comprising the new data; andtransmits the report to the head end through the microportal and collector. 10. The system of claim 9, wherein the first network comprises a home area network (HAN), the second network comprises a neighborhood area network (NAN), and the third network comprises a wide area network (WAN). 11. The system of claim 9, wherein the first node has a secondary power source. 12. The system of claim 11, wherein the secondary power source is a super-capacitor. 13. The system of claim 11, wherein the secondary power source is a battery. 14. The system of claim 9, wherein the head end server further generates an alarm report if the power outage report is confirmed. 15. The system of claim 9, wherein the head end server further displays an alarm message at a utility office if the power outage report is confirmed. 16. The system of claim 9, wherein the head end server further displays an alarm message at a display coupled to the first network if the power outage report is confirmed. 17. A method of verifying a power outage comprising: failing, by a head end, to receive a report from a first node coupled to a first network at a prescheduled reporting time window;polling, by the head end server, one or more other nodes coupled to the first network about a power outage, in response to failing to receive the report;determining that the power outage exists based on responses from the one or more other nodes;transmitting, by the head end server, a request to download any untransmitted information from the first node;receiving, by the first node, the request to download all untransmitted information;determining, by the first node, that untransmitted information is present in one or more tables stored in a memory of the first node, the tables selected from the group consisting of a history logger table, an event table, a profile table, and a self-read table;creating, by the first node, a report comprising the untransmitted information;transmitting, by the first node, the untransmitted information; andreceiving, by the head end server, the untransmitted information from the node. 18.
