METHOD FOR IMPROVING ENERGY EFFICIENCY IN WIRELESS MESH NETWORK
First Claim
1. A method for using power resource in a wireless mesh network, the method comprising:
- a role discriminating step of discriminating mesh terminals into active mesh terminals that are to perform a data relay function and super-saving mesh terminals that are not to perform a data relay function in consideration of a network topology;
a power saving mode setting step of setting power saving modes such that 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;
a routing path generating step of generating a routing path in a tree form along the mesh terminals selected as the active mesh terminals; and
a data transmission step of transferring data along the generated routing path while the mesh terminals are in an active state,wherein the respective steps are repeatedly performed at every certain period.

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.
