PURPOSE: A sensor node and routing method are provided to reduce the broadcasting number of routing information by improving the efficiency of routing information broadcasting. CONSTITUTION: When routing information is received, a routing information collection unit(120) collects routing information which is received during a waiting time. A node selection unit(130) collects one or more routing information received during the waiting time when the waiting time is finished. The node selection unit selects an optimized parent node. A routing information dividing unit(100) divides routing information to a preamble size. The routing information dividing unit transmits the divided routing information to other node. |
