    Abstract: According to an embodiment of the present invention, a method for receiving contents in a node of an overlay network is provided. A method for receiving contents receives contents from a node which transmitted a response for a contents inquiry message by flooding the contents inquiry message to an overlay network according to the minimum spanning tree when the node which received contents identification information from a user equipment does not have the contents. [Reference numerals] (201) Smart node 1;(202) Smart node n_1;(203) Smart node n_2;(AA) User equipment;(BB,EE,GG) Yes;(CC,DD,FF) No;(S200) Contents identification information;(S201,S205) Possessing the current contents?;(S202,S209) Serving smart node;(S203,S211) Providing contents;(S204) Flooding the contents inquiry message;(S206) Ignoring the contents inquiry message;(S207) Contents response message;(S208) Requesting contents transmission;(S210) Transmitting the contents
