Abstract
An address assigning method in a ZigBee network environment formed of a plurality of devices (or nodes), includes: linking the plurality of nodes in a cluster-tree structure; requesting desirable address blocks from a lowest level to a second highest level of the tree ancestor nodes desirable address blocks, respectively; and assigning the desired address blocks to descendents using a top-down procedure.
