摘要
针对无线传感器网络中DV-Hop定位精度较低,且定位精度完全依赖于未知节点到对应锚节点的跳数以及平均跳距的测量精度这一问题,提出一种改进型DV-Hop算法。通过仿真实验表明,在节点个数、通信半径、以及锚节点率一定时,该算法的平均定位误差比DV-Hop的平均定位误差分别减小25%,19%和22%。
According to the lower localization accuracy of DV-Hop algorithm in WSN,as well as,itslocalization accuracy based on the distance between unknown nodes and anchor nodes,and the measure-ment precision of average jump distance,this paper presents an improved DV-Hop algorithm. The simula-tion results show that：when nodes numbers、communication radius and anchor nodes rates are under givenconditions,average positioning error of the improved algorithm has been reduced 25%,19% and 22% res-pectively.
