On the Security Enhancements of Wireless Sensor Network

This paper studies the fabricated report with false votes on real reports attack in wireless sensor networks. To deal with secondary attack, we propose a probabilistic voting-based scheme (PVS). On the basis of the en-route filtering scheme, PVS combines cluster-based organization, probabilistic key assignment, and voting methods. Through analysis and simulation, we demonstrate that PVS could achieve strong protection against both attacks while maintaining a sufficiently high filtering power.
