摘要

在无线传感器网络中节点的自身定位技术是支撑性的技术。研究了DV-Hop算法

并分析了其缺点。针对其缺点修正了锚节点的计算的平均每跳距离

让更多的锚节点参与最后的定位计算并采用了加权的质心算法。通过Matlab仿真改进的算法能明显地提高定位的精度

得出改进算法适合的应用场景。

Abstract

Self-positioning technology is a supportive technology in wireless sensor networks.The shortcomings of DV-Hop algorithm is analyzed and amending the anchor node’s calculation of the average distance of each hop.More anchor node is allowed to participate in the final position calculation and the weighted centroid algorithm is adopted.The result of the simulation by Matlab shows that the modified algorithm is better than the original one in precision.The suitable application scene of the modified algorithm is derived.
