Abstract

An apparatus and method for setting a role based on capability of a terminal are provided. The apparatus includes a calculation unit calculating a capability value of the terminal to check whether the role set in a pertinent terminal is suitable, a determination unit determining whether the role set on the pertinent terminal is suitable based on the calculated capability value, and a setting unit changing and managing information for setting the role set in the pertinent terminal.

Claims

1. An apparatus for setting a role based on a capability of a terminal, comprising:

a calculation unit which calculates a capability value of the terminal;

a determination unit which determines whether the set role of the terminal is suitable based on the calculated capability value; and

a setting unit which manages information regarding the set role in the terminal.

2. The apparatus of claim 1, wherein information used in calculating the capability value comprises network performance, remaining battery power, and usability of resource.

3. The apparatus of claim 1 further comprising a controller which controls the terminal to have a supernode role or a leaf node role based on the information regarding the set role managed by the setting unit.

4. The apparatus of claim 3, wherein the terminal is a first terminal and if the set role in the first terminal is changed from a supernode into a leaf node, the controller searches for a second terminal, and transmits reference information for a leaf terminal stored in the first terminal, to the second terminal.

5. The apparatus of claim 3, wherein the terminal is a first terminal and if the set role in the first terminal is changed from a leaf node into a supernode, the controller searches for a second terminal positioned next to the first terminal on a key space, and makes a request for reference information of a leaf terminal to the second terminal next to the first terminal.

11. The apparatus of claim 4, wherein the second terminal is a next super terminal.

12. The apparatus of claim 5, wherein the second terminal is a super terminal.

6. A method of setting a role based on capability of a terminal, comprising:

calculating a capability value of the terminal;

determining whether the set role set of the terminal is suitable based on the calculated capability value; and

managing information regarding the set role in the terminal.

7. The method of claim 6, wherein information used in the calculating the capability value includes network performance, remaining battery power, and usability of resource.

8. The method of claim 6, further comprising performing a supernode role or a leaf node role based on the information regarding the set role of the terminal.

9. The method of claim 8, wherein the terminal is a first terminal and the method of claim 8 further comprises, if the set role of the first terminal is changed from a supernode into a leaf node, searching for a second terminal;

and

transmitting reference information for a leaf terminal stored in the first terminal, to the second terminal.

10. The method of claim 8, wherein the terminal is a first terminal and the method of claim 8 further comprises, if the set role of the first terminal is changed from a leaf node into a supernode, searching for a second terminal positioned next to the first terminal on a key space;

and

making a request for reference information of a leaf terminal to the second terminal next to the first terminal.

13. The method of claim 9, wherein the second terminal is a next super terminal.

14. The method of claim 10, wherein the second terminal is a super terminal.
