Abstract: Embodiments are disclosed for saving power in a gateway network comprising a plurality of nodes including a gateway device and one or more endpoint devices. In the context of a method, an example embodiment includes determining a mode of operation that results in optimal power utilization of at least one node, and determining whether a current mode of operation comprises the mode of operation that results in optimal power utilization of the node. In response to determining that the current mode of operation does not, the method further includes generating a mode switch message based on the mode of operation that results in optimal power utilization of the node, and causing transmission of the mode switch message to a first subset of the one or more endpoint devices. A corresponding apparatus and computer program product are also provided.
