Abstract: A new localization algorithm based on reputation mechanism was proposed to improve the robustness of the node positioning system in Wireless Sensor Network(WSN).This algorithm introduced a monitoring mechanism and reputation model to filter out malicious beacon nodes giving the false location information,used Beta distribution to update and integrate the reputation of the beacon nodes.Through the cluster head node,the proposed algorithm collected and judged which beacon nodes were reliable,increased the malicious beacon nodes detection rates while the positioning error was reduced.Finally,the simulation and detailed analysis prove its efficiency and robustness.The algorithm is efficient in self-positioning of sensor nodes in distributed WSN,and the localization accuracy and security are greatly improved.
