PURPOSE: A congestion prediction method of a wireless sensor network is provided to minimize packet loss by previously predicting created packet and by charging congestion passage money to a location where is predicted as a congestion location. CONSTITUTION: A wireless sensor network includes one or more sensor nodes connected with a sync node and the sync node. The modeling of the wireless sensor network is modeled(110). When the created packet of the sensor node is transmitted to the sync node, the section traffic of the network is calculated(130). The congestion costs of a packet which passes through the congestion section of the network are calculated by using the section traffic of the network(150).
