Abstract
Systems and methods are disclosed for detecting and reporting node power outages in a connected network. A node in the network detects that a power outage has occurred at the node and the node generates a last gasp packet using a packet format containing fewer data units than a regular packet format used by the network for communication. The node broadcasts the last gasp packet to its neighboring nodes. After receiving the last gasp packet, a neighboring node estimates the time of the power outage and converts the last gasp packet into an outage alarm message using the regular packet format. The neighboring node transmits the outage alarm message to a headend system to report the power outage at the node.
