Nodes in sensor networks 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 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. Thus, we should choose a threshold value such that it provides sufficient resilience, yet is small enough to conserve energy. This paper presents a fuzzy-based threshold determination method for the dynamic en-route scheme to filter false reports in wireless sensor networks. The base station periodically determines the threshold value using a fuzzy rule-based system. The resilience and energy efficiency of the proposed method against false data injection attacks are shown by simulation.
