Abstract: In the environment of wireless sensor networks (WSN), the techniques that assume benign environments might be subverted by malicious nodes that lie about their own locations or distances from the nodes to be localized. This pa-per proposes a secure and efficient scheme called secure localization algorithm based on multi-resolution clustering. The scheme can effectively eliminate malicious nodes and impede attacks by the clustering of proximal points got from the bound circles using an iteratively voting scheme. Simulation results indicate that the proposed algorithm can provide better performance with shorter execute time and higher localization accuracy.
