Apparatus for data aggregation using zone scheduling in wireless sensor network and method thereof

A computer-readable storage medium storing a program for implementing a data aggregation method, the method comprising:

• generating a plurality of data aggregation trees according to a connection relationship of clusters of sensor nodes which configures a wireless sensor network using a geographical code (GGC);
• selecting a single activation zone for each of the clusters which configures each of the plurality of data aggregation trees;
• selecting a maximum energy tree, the maximum energy tree corresponding to one of the plurality of data aggregation trees having a maximum total residual energy based on the single activation zone;
• and
• generating a tree list including activation zone information which corresponds to the maximum energy tree, and information about the maximum energy tree.

A data aggregation apparatus comprising:

• a tree generation unit for generating a plurality of data aggregation trees according to an association of clusters of sensor nodes in a wireless sensor network using a geographical code (GGC);
• a zone scheduling unit for selecting a single activation zone for each of the clusters which configures each of the plurality of data aggregation trees;
• a tree selection unit for selecting a maximum energy tree having a maximum total residual energy from the plurality of data aggregation trees based on the activation zone;
• and
• a list generation unit for generating a tree list including activation zone information which corresponds to the maximum energy tree, and information about the maximum energy tree.
