Threshold Determining Method for the Dynamic Filtering in Wireless Sensor Networks Based on Fuzzy Logic

In sensor networks, nodes can be easily compromised by an adversary because of hostile environments. An adversary may use compromised nodes to inject false reports into the network. The dynamic en-route scheme for filtering false data injection can detect and drop such false reports during the forwarding phase. In this scheme, choosing a threshold value is important, as it trades off between security power and energy consumption.
