Selecting Votes for Energy Efficiency in Probabilistic Voting-based Filtering in Wireless Sensor Networks Using Fuzzy Logic

Wireless sensor networks are easily compromised by an adversary, such as fabricated with false votes attacks and false votes on real reports attacks. These attacks generate false data to drain the energy resource of sensors and interrupt the inflow of a real report. PVFS was proposed to detect them by verifying votes in the real report. When a real event occurs, a cluster head collects all of the votes from its neighboring nodes and selects the votes up to a defined number of votes. In this paper, our proposed method decides the number of votes based on a fuzzy rule-based system to improve energy savings as compared to PVFS. We evaluated the effectiveness of the proposal as two attacks occur simultaneously in the sensor network. The experimental results show that our method saves energy resources and maintains the security level against these multiple attacks.
