Communication method of a content requester, an intermediate node of one or more intermediate nodes, and a content owner in a content centric network are provided. A communication method of a content requester in a content centric network (CCN) includes, where the CCN includes the content requester, one or more intermediate nodes, and a content owner, generating a content request packet including a cache token, the cache token being used to determine one or more of the intermediate nodes in which to store content requested from the content owner, and transmitting the generated content request packet to the intermediate nodes and the content owner.

A Content-Centric Network and a method of performing routing between domains therefor are provided. The method includes identifying a route from an anchor hub in a first domain to one or more hubs in the first domain, the anchor hub being configured to store routing information between a first border hub of the hubs in the first domain and a second border hub in a second domain, detecting, by each of the hubs in the first domain, a neighboring hub based on a sync direction corresponding to the identified route, and sharing the routing information with the neighboring hub, the sharing of the routing information including performing a sync operation between the neighboring hub and each of the hubs in the first domain.

A data transmission apparatus and a data apparatus, are provided. The apparatuses may share data in a Peer-to-Peer (P2P) scheme via a network. The data transmission apparatus divides data into a plurality of segments, and determines a transmission order with respect to each of the divided segments. The data transmission apparatus and the data apparatus share data based on the transmission order of the divided segments.

A channel search method for a vertical handoff in a wireless network environment is provided, the channel search method including: collecting channel information from a first terminal which is provided with a wireless local area network (WLAN) service via a channel connection with a WLAN node; and determining a channel search order for a channel connection between a second terminal and the WLAN node by using the collected channel information. A channel search system for a vertical handoff in a wireless network environment is also provided, the channel search system including: a channel information collection unit for collecting channel information from a first terminal which is provided with a WLAN service via a channel connection with a WLAN node and a search order determination unit for determining a channel search order for a channel connection between a second terminal and the WLAN node by using the collected channel information.

Provided is a method of controlling a home hub in a virtual group that may provide a geographical boundary about the virtual group by associating an identifier of a network of a virtual group included in an access point list with a name of the virtual group and a name of the home hub managing the virtual group, and may provide a terminal which moves to a visited virtual group with information about a network of the visited virtual group, thereby facilitating recognition of a virtual group and content sharing.

In a network system based on a content name, a terminal device may generate and transmit a block query requesting a plurality of segments, and may receive segments corresponding to the block query based on a transmission direction of the block query.

Provided are a content source node and a first content router and a second content router in a content centric network (CCN), and a communication method thereof. The technology described herein may reduce the updating of routing information due to a movement of a mobile source node and the corresponding overhead, thereby reducing a rate of using an overall network resource by adding routing information, that is, partially updating the routing information of the corresponding mobile source node for content routers on a route through which the mobile source node moves.

Provided are a method and apparatus for sharing content, using information regarding a group change in a content oriented network environment. In a case where a group to which a target user equipment belongs is changed from a first group to a second group, the target user equipment may transmit, to a first group member management device, the information regarding the group change. The first group member management device may update information about a group to which the target user equipment currently belongs, based on the information regarding the group change. In response to a receiving of a content request from a requesting user equipment, the first group member management device may transfer the content request to the target user equipment.

A method of communication for a terminal in a content-centric network is provided. The method includes suspending a data message associated with a content from being provided to a face before a handover when the handover is expected to occur in the terminal that requests the content, and transmitting, to a hub, a new interest message after the handover associated with the content so that the hub may provide the data message associated with the content to the face after the handover.
