Energy Efficient Anomaly Detection of Wireless Sensornets

Anomaly detection is essential to many wireless sensornet applications.A key challenge is to detect anomalies with an acceptable accuracy and meanwhile to minimize energy consumption.An energy efficient anomaly detection algorithm is proposed.It consists of three phases: correlation analyzing,network clustering and anomaly detection.First,sensor nodes compute data correlations collaboratively.Then,a clustering procedure is conducted to divide the network into several sub-nets based on the node correlation a...
