Abstract
A method for effectively using power resource in a wireless mesh network is disclosed to select and change a level of a power saving mode according to terminal and network situations to increase the duration of the network's existence as well as improve the power consumption of each mesh terminal. After active mesh terminals that are to perform a data relay function and super-saving mesh terminals that are not to perform the data relay function are selected in consideration of a network topology at certain periods, the level of a power saving mode of the mesh terminals selected as the super-saving mesh terminals is higher than that of the mesh terminals selected as the active mesh terminals. And then, a routing path in a tree form is formed along the mesh terminals selected as the active mesh terminals to transmit data.
