Abstract: In a method for communicating among a plurality of nodes in a content-centric networking environment, each of a plurality of nodes selects at least one relay node based on topology information on neighbor nodes adjacent within 2 hops from itself. Each of the selected relay nodes determines whether itself is a publisher relay node. Each of the determined publisher relay nodes generates a multi-hop content announce (CA) message including content information of its own 1-hop neighbor nodes, and broadcasts the multi-hop CA message to the plurality of nodes through the selected relay nodes.
