摘要

In this paper, a three-dimensional node security localization method for WSN based on improved RSSI-LSSVR algorithm was proposed, which aims to improve the accuracy and security of the traditional wireless sensor network localization algorithm in three-dimensional environment. The RSSI method is first improved is improved by using the median weighting method so as to improve the range precision of the nodes. To further improve the localization accuracy of the nodes, a three-dimensional node localization model is established based on the least square support vector regression method. Lastly, a detection mechanism against sybil attacks is presented to improve the security of localization against sybil attacks. The simulation results show that the accuracy and safety of the improved localization algorithm are better than the traditional localization algorithm.
