Abstract
An address assignment method of a mobile node, for hierarchical routing in a low-power wireless personal area network (LoWPAN), includes (a) classifying a plurality of fixed nodes in a hierarchical way, (b) designating a management node and a head node of a lower level than the level of the management node in the fixed nodes, (c) determining if the mobile node can communicate with the head node, and (d) assigning an address to the mobile node through a neighboring head node, which can communicate with the mobile node when the mobile node cannot communicate with the head node. Therefore, addresses may be assigned without limitation until the addresses for the mobile nodes are exhausted. Furthermore, even when the mobile node having an assigned address from a first region moves from the first region to a second region, the packet may be sent or received through the hierarchical routing.
