摘要 为提高无线传感器网络节点定位精度,文章提出了一种基于移动信标节点加余弦定理的MCDV-Hop改进算法。该算法从改变移动信标节点移动轨迹基础上通过余弦定理修正跳距,在模拟WSN场景下,通过仿真实验表明,MCDV-Hop改进算法提高了网络资源利用率,在一定程度上表现出较稳定的定位精度。 In order to improve the positioning accuracy of DV-Hop positioning algorithm,proposed an improved DV-Hop algorithm based on mobile anchor nodes and cosine theorem.On the basis of changing the moving trajectory of mobile anchor nodes,the algorithm fixes the jump distance by cosine theorem.Simulation shows that MCDV-Hop improved algorithm enhanced the utilization of network resources,showed more stable positioning accuracy to some extent.
