In this paper, we propose a localization algorithm to defend against independent attacks and collusion attacks. In the algorithm, we first select three random reference nodes, then use the trilateral detection method and the confidence interval to get rid of the malicious nodes. We then use the PSO optimization algorithm to locate the unknown node, is called (Secure localization algorithm against advanced attacks-SL4A). |
