摘　　要：DV-Hop是无线传感器网络中典型的定位技术,建立DV-Hop的定位误差模型有助于定量分析定位误差,进一步提高WSN的定位精度。首先从理论的角度分析了定位误差与覆盖度的关系,然后通过仿真实验讨论了一定通信半径下局部范围内相对定位误差与覆盖度的关系,并给出相应的数学模型。实验表明:该模型可有效估计基于局部区域定位算法的定位误差。DV-Hop is a typical location technology in wireless sensor network.Building a location error model and analyzing the location error quantificationally in DV-Hop are in favor of improving location accuracy in WSN.Firstly the relationship of the location error and the coverage from the angle of the theory were analyzed,and then the relationship of the relative location error and the coverage under the Restricted Communication Radius through the simulation experiment was discussed,and the corresponding mathematical model was given.The experiment shows that this model can estimate the location error based on local area effectively.
