摘要: 在传统DV-Hop无线传感定位算法的基础上,针对精准灌溉的特点提出改进算法并进行仿真实验。新算法借助边界锚节点计算平均每跳距离,并采取伸缩法修正了超出簇覆盖范围的节点坐标。

Abstract: Aiming at the characteristics of precision irrigation,this paper proposes a refined algorithm and simulation experiments on the basis of the traditional DV-HOP wireless sensor localization algorithm.The new algorithm uses outer anchor nodes to calculate the average single hop distance,and takes scaling method to revise the coordinates of nodes which are beyond cluster coverage.

Key words: precision irrigation, wireless sensor networks, localization
