1. A data aggregation 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.
