中文摘要DV-Hop location algorithm is very suitable for the application of large-scale sensor network. But it requires the estimation of average hop distance, which lowers down the positioning accuracy. Current popular method is to improve the average hop distance and localization process for unknown nodes through Maximum Likelihood Estimation method or Least Square method. The positioning accuracy of these mentioned methods has been raised. However, it is easy for the position estimation to combine high residual error into the computing process, which will give rise to the localization error along with computational complexity. Considering existent problem, this paper employs Residual Weighting Algorithm to estimate the positions of unknown nodes by improving the calculating mode of average hop distance. For the position estimation with high residual error, we assign a relatively low weight to inhibit its influence. Thus the accuracy and computing process are effectively improved. The experimental results demonstrate that the proposed method can greatly improve the positioning accuracy of unknown nodes, reduce the computational complexity and boost the calculation efficiency.
