Efficient Key Dissemination Method Using Fuzzy Logic Based Dynamic En-route Filtering

摘要

Sensor nodes are deployed in open and unattended environments in wireless sensor network applications. An adversary can easily compromise sensor nodes due to these features. False reports can be injected through compromised nodes that can lead to false alarms and the depletion of the limited energy resources in a battery powered network. Yu and Guan proposed a dynamic en-route filtering scheme that can detect and drop false reports. Choosing a threshold value is important in this scheme, as it trades off between security and energy consumption. Therefore, we should choose an appropriate threshold value. In this paper, we propose a fuzzy logic based key dissemination method.
