摘要
针对无线传感器网络定位的DV-Hop定位算法定位精度不足,文中提出了一种改进后的DV-Hop算法。改进后的算法在原基础上引入了均匀量化模型来提高每段跳距的精度和最小二乘法以解决定位过程中造成的累积误差。仿真结果证明,改进后的算法显著的提高了未知节点的定位精度。
As a result of the shortage of the positional accuracy for DV-Hop location algorithm in wireless sensor networks, the article proposes a modified DV-Hop algorithm. The improved algorithm introduce uniform quantization model into the original one to improve the accuracy of every period of jump distance and least square method to solve accumulated error in the location. The simulation results prove that the improved algorithm has prominent improve- ment in positioning accuracy of unknown nodes.
