Techniques are described herein to equip backup power for some key nodes and form the local Directed Acyclic Graphs (DAGs) rooted at the first hop node with backup power. Nodes have different preferred parents in different work states. In normal state, nodes behave like existing mesh networks and have no performance sacrifice. In Power Outage Notification (PON) state, nodes can unicast the PON messages to their PON state’s parents to improve PON message transmission efficiency and reliability.
