ENERGY-SAVING MOBILE NODE CONTROL METHOD USING WIRELESS MULTI-INTERFACES
First Claim
1. An operating method of a node control apparatus connected to an external Internet Protocol (IP) network and a local network, the operating method comprising:
- managing information relating to a plurality of mobile nodes in the local network, each equipped with one or more wireless interfaces;
configuring one or more groups by classifying the plurality of mobile nodes according to the type(s) of the wireless interface(s) of each of the plurality of mobile nodes;
selecting a representative node for each of the groups; and
allowing one or more member nodes of each of the groups to communicate with the external IP network via their representative node.

Abstract
Provided is a node control apparatus communicating an external Internet Protocol (IP) network and managing a plurality of mobile nodes included in a local network. The node control apparatus manages information relating to the plurality of mobile nodes, each equipped with one or more wireless interfaces, configures one or more groups by classifying the plurality of mobile nodes according to the type(s) of the wireless interface(s) of each of the plurality of mobile nodes, selects a representative node for each of the groups, and allows the member nodes of each of the groups to communicate with the external IP network via their representative node. Therefore, it is possible to minimize power consumption by selectively using a wireless interface for use in connecting to the representative node of each of the groups.
