As a promising application in WSN, there is an anomaly detection using the sensor information. In the anomaly detection, to the acquired sensor information based on the abnormality of the water quality in rivers, detects weather anomalies as familiar, it is to report to the user. Further, in the WSN, the problem sensor price and power consumption, it is difficult to provide all sensors required for anomaly detection in all nodes. Therefore, it is required to share the expensive sensors in the network. We propose an autonomous distributed WSN systems sharing a limited sensor resources at high speed between the nodes, with improved anomaly detection rate by the node in the WSN.
