PURPOSE: A self-composition system of a wireless sensor network and a self-composition method thereof are provided to connect all devices while minimizing a routing delay. CONSTITUTION: A parent device(200) receives a subscription request from a child device(300) of a lower hierarchical tree stage. The parent device selects the child device to subscribe to the parent device. The parent device allocates an address to the child device subscribing to the parent device. The child device selects the parent device of an upper hierarchical tree stage. The child device performs the subscription request. The child device subscribes according to the selection of the parent device to receive the address. [Reference numerals] (200) Parent device; (210) Child router selecting unit; (220) Multi-step tree based address assignment unit; (230) Child terminal device selecting unit; (300a) Sensor device which wants to join through a router; (300b) Sensor device which wants to join through a terminal device; (310a) Parent selecting unit for routers; (310b) Parent selecting unit for terminal devices; (AA,BB) Admission request; (CC) Router address; (DD) Terminal device address |
