摘要
针对当前DV-Hop算法存在的传感器节点定位误差大、定位效率低、抗干扰能力差等问题,设计了一种基于改进DV-Hop算法的传感器节点定位方法。首先,采用DV-Hop算法对传感器节点的位置进行初步估计;然后,将DV-Hop算法的传感器节点定位结果作为斯蒂芬森迭代模型的初始值,通过斯蒂芬森不断迭代得到最优传感器节点位置;最后,与其他传感器节点定位算法进行了仿真对比测试。结果表明,本文方法传感器节点定位误差小,传感器节点定位的平均耗时明显缩短,定位效率得到了明显提升。
To overcome the shortcomings of current DV-Hop algorithm,such as low positioning accuracy,low positioning efficiency and poor anti-interference ability,a sensor node positioning mechanism based on improved DV-Hop algorithm was designed to achieve ideal positioning effect.Firstly,the factors of large sensor node location error in DV-Hop algorithm were analyzed,and corresponding improvements were made.Then,DV-Hop algorithm was used to estimate the location of sensor nodes preliminarily,and DV-Hop algorithm was used as the initial value of Steffensen iteration model.The optimal sensor node location was obtained through Steffensen iteration.Finally,the simulation results were compared with other sensor node localization algorithms.The results show that the positioning error of the proposed mechanism is small.The average time of sensor node positioning is significantly shortened,and the efficiency of sensor node positioning is significantly improved.
