Abstract: A method for efficiently transmitting contents on a network is provided. The content transmission method using social information, includes: requesting content registration and social information of a user; allocating, by a social information management node, a multicast address to be used in content transmission based on the content registration information and social information received from a social service provider; transmitting the allocated multicast address to a first access control node to which a first user terminal is connected so as to set the first access control node as a multicast source, in response to a request of the first access control node; and transmitting a response message to a second access control node for setting a multicast transmission path for content transmission between the first access control node and the second access control node when there is a sharing request of the second access control 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.
