PURPOSE: A sensor node, an address assigning method, and a message transmitting method thereof are provided to efficiently use an ID storage space of sensor nodes and to simultaneously cope with a dynamic change of the sensor node. CONSTITUTION: A jump ID calculating unit(506) calculates a jump ID using an jump ID of a parent node, a rank number of the jump ID calculating unit, and maximum child number information of a tree with a root. A jump table management unit(508) generates and manages a jump table. The jump table includes the real ID of the jump table, the jump ID, and the real IDs and the jump IDs of an ancestor node and a child node.
