Apparatus and method for power saving of the ad hoc network

Examples of such means cause the arbiter server arbitration system includes a node from the ad hoc network receives route information in the plurality of nodes or a copy of the message to determine a route between the nodes, the node transmits during the routing protocol or received routing information message, according to e.g. gossip algorithms. Cause the apparatus to route a message based on the information, the identification information intended to also receive the routing node as a message or a desired part of the determined route of. And promote ready for transmission to one or more nodes of the instruction message means that one or more identified nodes enter or remain in an active mode, and one or more different nodes of the identified nodes enters or remain in power-saving mode.
