Intrusion Detection in Heterogeneous Wireless Sensor Networks Using Multi-Layer Multi Detector Approach
In a WSN, there are two ways to find out inconsistency of object (i.e., an outlier) single-sensing find threat and multiple-sensing find threat. In the single-sensing find threat, the outlier can be successfully find threat by a single user sensor node. On the area, in the multiple-sensing find threat, the outlier can only be find threat by multiple cooperating user sensor nodes. In some applications, the sensed information provided by a single user sensor node might be poor for recognizing the attacker. It is because particular user sensor nodes can only sense a portion of the outlier.
