To improve the accuracy and stability of real-time positioning of wireless sensor network nodes,this paper uses CC2430 microcontroller to design an embedded hardware platform,and combines the least squares method and improved bat algorithm to design a positioning system scheme.By optimizing hardware circuit design,improving bat algorithm,and designing multi constraint optimization models,the goal of adapting to node positioning requirements and improving positioning accuracy can be achieved.The experimental results show that the average positioning error of the positioning system designed in this paper is 0.21,the maximum intrusion rate is less than 1%,and the performance is significantly better than the comparative scheme.The research results can provide new technical solutions for real-time positioning of wireless sensor network nodes,and have good theoretical and practical value.
