Abstract
Various embodiments disclose a method including detecting, by a first node in a mesh network while the first node is operating in a normal power mode, an outage event; in response to detecting the outage event, switching to operating the first node and a first memory of the first node in a low power mode, wherein the first memory is capable of switching between operating in the normal power mode and in the low power mode where an amount of power used by the first memory is reduced; and while operating the first node and the first memory in the low power mode: generating, by the first node, a first message; securing, by the first node using a key retrieved from the first memory, the first message; and sending, by the first node, the first message to a second node in the mesh network.
