[0087] Examples:
[0088] Such as Figure 5 As shown, 200 wireless sensor nodes are randomly deployed in a uniform distribution in a three-dimensional space of 200m×200m×200m; in the figure, the anchor node is a solid five-pointed star, the proportion is 20%, and the ID is 1-40; the unknown node is solid The dot, the ratio is 80%, and the ID is 41-200.
[0089] The node positioning method and the distance vector method of the present invention are respectively used for node positioning, and the positioning error of each node is obtained as Image 6 As shown, the solid line in the figure is the positioning error of each node obtained using the method of the present invention, and the average positioning error is 23.45%; the dotted line in the figure is the positioning error of each node obtained using the distance vector method, and the average positioning error is 43.67%; Compared with the distance vector method, the method of the present invention can improve the positioning accur...
