A Fuzzy Trust Assessment Technique Using Entropy-Based Weighting in Wireless Sensor Networks

- Record updated
Summary
This paper proposes EFTE, an Entropy-Weighted Fuzzy Trust Evaluation framework for Wireless Sensor Networks. EFTE scores node trust from communication efficiency, remaining energy, behavioral consistency and mobility, using entropy-based weighting, a fuzzy inference system and adaptive thresholding to isolate untrusted nodes. Simulations and a hardware prototype on low-cost IoT devices reportedly show higher malicious node detection accuracy, fewer false positives, better packet delivery ratio and longer network lifetime.
