| 摘 要： | DV-Hop 算法是解决无线传感器网络节点定位问题的一种经典算法。文中根据经典的DV-Hop 算法提出了一种改进算法，通过引入更优的误差矫正和双曲线定位算法，减少了经典算法中多跳过程中积累的定位误差。比较和分析了经典DV-Hop 算法和改进后算法的仿真结果可以看出，改进后的DV-Hop 算法定位精度提高显著，在给定条件下的定位误差下降了约50%。

| Abstract: | The DV Hop algorithm is a classical algorithm for node localization in wireless sensor networks. In this paper, an improved algorithm is proposed based on the classical DV Hop algorithm to reduce the positioning error accumulated in the multi hop process by introducing a better error correction and the hyperbolic location algorithm. After comparing and analyzing the classical DV Hop algorithm and the improved algorithm, the simulation results show that the improved DV Hop algorithm can improve the positioning accuracy significantly, with the positioning error reduced by about 50% under the given conditions. |
