针对传统算法在对分布式无线传感器网络定位结果中存在平均定位误差较高的问题,开展对其定位算法的研究,提出一种基于DV-HOP的分布式无线传感器网络定位算法。通过分布式无线传感器网络定位节点筛选、节点可信度计算以及基于DV-HOP的未知节点平均跳距计算,实现基于DV-HOP的分布式无线传感器网络精准定位。通过对比实验证明,该算法与传统算法相比可以有效降低定位结果的平均定位误差,有效提高节点定位的精准性,且耗时更少。

In view of the problem that the traditional algorithm has high average positioning error in the positioning result of wireless sensor network,the research on its positioning algorithm is carried out,and a distributed positioning algorithm based on DV-HOP is proposed.Through the selection of localization nodes,the calculation of node reliability and the calculation of average hop distance of unknown nodes based on DV-HOP,the precise localization of distributed wireless sensor network based on DV-Hop is realized.Compared with the traditional algorithm,this algorithm can effectively reduce the average positioning error of positioning results and improve the accuracy of node positioning.
