Method of and apparatus for managing neighbor node having similar characteristic to that of active node and computer-readable recording medium having recorded thereon program for executing the method

An apparatus for managing a neighbor node having a similar characteristic to that of an active node, the apparatus comprising:

• a neighbor list generation unit to generate a neighbor list comprising information about neighbor nodes;
• a parent node selection unit to select parent nodes from among the neighbor nodes;
• a fitness parameter determination unit to determine fitness parameters by using a characteristic value of the active node, characteristic values of the neighbor nodes included in the neighbor list of the active node, and characteristic values of neighbor nodes included in a neighbor list of each selected parent node;
• and
• a neighbor list update unit to update the neighbor list of the active node according to values of the determined fitness parameters.
