Abstract: A user terminal for preventing communication interruption during handoff in an information-centric network is provided. The user terminal includes a connection registration unit configured to register the user terminal in an access node for connection to the access node, and a communication interruption prevention unit configured to receive, from the access node in which the user terminal is registered, zone information including identification information on other access nodes that are candidate handoff targets of the user terminal, and transfer the zone information to a counterpart communication device that currently performs communication, wherein the user terminal receives a message from the counterpart communication device through one of the other access nodes that are candidate handoff targets during the handoff. Accordingly, communication interruption is prevented.

Abstract: Provided are a method of communicating content in a mobile ad-hoc network and a communication node included in a mobile ad-hoc network, the method and communication node intended to efficiently perform communication based on information centric networking (ICN) in a mobile ad-hoc network and reduce the waste of energy resulting from frequent reconfiguration of communication caused by the mobility of a terminal. The method includes receiving an interest packet or a response packet for content; determining a next node to which the received packet will be relayed based on a forwarding information base (FIB) or a pending interest table (PIT), and relaying the packet using a unicast scheme; and when the relay of the packet to the next node fails, restoring a routing path by storing the packet in a relay candidate buffer and broadcasting the packet.
