Wireless Sensor Networks (WSNs) are ad-hoc mobile networks that contain sensor nodes with limited energy resource and wireless communication facilities. WSNs are typically deployed in wide, unattended, and hostile areas. Therefore, sensor nodes are subject to compromise physically and surreptitious use by an adversary. An adversary can capture them to inject an incorrect data into the sensor field, which causes unnecessary energy consumption of nodes. A dynamic en-route filtering scheme is proposed to detect and drop the fabricated data as soon as possible. In this scheme, the authentication keys used to verify event reports are redistributed to neighbour nodes to enhance the detection power during the post-deployment phase. In this paper, we present a fuzzy based key redistribution determining method in which when keys are redistributed to neighbour nodes to determine by a fuzzy system with the network situation. The proposed method can provide more efficient energy consumption and sufficient detection power.
