PURPOSE: A method for setting a routing path in a Zigbee network is provided to maintain a routing path of a sensor node, 1 which is in a lost state due to the service refusal attack, as an optimal routing path continuously. CONSTITUTION: A state identifier included in beacon message is extracted(S3), and an operating state of a Zigbee network is judged based on the extracted state identifier(S5). When the operating state of the Zigbee network is judged as the configuration state based on the judged operating state, the routing path of the nodes which belong to the Zigbee network is set in the mode depending on the configuration mode(S7). When the operating state of the Zigbee network is judged as the operating state, the routing path of the Zigbee network set in the configuration state is maintained continuously(S9).
