Abstract: Systems and methods for performing node maintenance on network nodes in a communication network are provided. The network nodes can be in communication with a node management device that can control when each network node is in a sleep state and in an awake state as part of a check-in cycle where the network nodes report to the node management device. When maintenance is required on the network nodes, the node management device can increase the amount of time used during the check-in cycle to account for the time needed to perform maintenance on one of the network nodes. The node management device can then use this additional time to perform the required maintenance on one of the network nodes. The remaining network nodes that are not receiving the required maintenance are provided with an extended sleep time to permit the one network node to receive maintenance.
