Abstract
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.
