Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of using power resources in a wireless mesh network by which the power consumption of mesh terminals can be reduced and the life time of a network can be increased by selecting and changing the level of a power saving mode depending on the terminals and a network condition. SOLUTION: From the mesh terminals, an active mesh terminal for data relay and a super saving mesh terminal not for data relay are periodically selected in consideration of the network topology. After that, the level of the power saving mode of the mesh terminal selected as the super saving mesh terminal in the selection is set higher than the level of the power saving mode of the mesh terminal selected as the active mesh terminal, a tree routing path is generated along the mesh terminal selected as the active mesh terminal, and data is transmitted.
