APPARATUS AND METHOD FOR SHARING DATA BY USING TOPOLOGY

1 . A method of sharing data by a host terminal, the method comprising:

creating a topology indicating a configuration of a wireless network between the host terminal and a plurality of adjacent terminals located within a standard distance from the host terminal;

transmitting the topology to the plurality of adjacent terminals;

receiving a participation request message for requesting a participation in the wireless network according to the topology from at least one of the plurality of adjacent terminals; and

sharing data, based on the topology, with at least one of the adjacent terminals having transmitted the participation request message.

2 . The method of claim 1 , wherein the creating of the topology comprises creating the topology that comprises information about at least one of a connection structure between a plurality of terminals in the wireless network and an access right to data according to the connection structure.

3 . The method of claim 2 , wherein the sharing of the data comprises:

receiving a data transmission signal from a user of the host terminal; and

transmitting the data to an adjacent terminal connected to the host terminal based on the connection structure.

4 . The method of claim 1 , wherein the creating of the topology comprises receiving information about a connection structure between a plurality of terminals in the wireless network from a user of the host terminal, and creating the topology based on the received information.

5 . The method of claim 1 , wherein the creating of the topology comprises:

extracting a plurality of pre-created topologies from a memory of the host terminal;

displaying the plurality of topologies on a display device of the host terminal;

receiving a selection signal on one of the plurality of topologies from a user of the host terminal; and

creating a topology corresponding to the selection signal as the topology indicating the configuration of the wireless network.

6 . The method of claim 1 , wherein the transmitting of the topology comprises transmitting the topology to the plurality of adjacent terminals using a near field wireless communication method, and

the sharing of the data comprises sharing the data using the near field wireless communication method.

7 . The method of claim 1 , wherein the creating of the topology comprises:

collecting information of at least one of locations and identifiers of the plurality of adjacent terminals; and

creating the topology based on the collected information.

8 . A non-transitory computer-readable media recording a program to implement the method according to claim 1 .
