Study of improving location accuracy of DV-Hop algorithm

The application restrictions of DV-Hop are broken through starting from its model.According to the principle of total least squarest,he location problem of sensors is studied in wireless sensor network when the anchor node location infor-mation exists errorsa,nd more general results are obtained.In the simulation scene with size 100×100,100 sensor nodesc,om-munication radius 30m,Gaussian noise variance 1 and the ratio of anchor node less than 8%t,he simulation demonstrates that this approach can improve the location accuracy of WSN significantly.Its average location accuracy increases by 20%~ 30% than the original method.The two methods tend to have the same accuracy when the ratio of anchor nodes is greater than 8%.
