摘要 本文在研究传统的DV-Hop3D算法基础上提出了一种新无线传感器网络定位算法。新算法在算法的第一阶段设置了跳数阈值参数以减小通信开销,并且在算法的第二阶段用可选择的平均跳距代替固定的平均跳距来计算未知节点到锚节点的距离,最后用Matlab7.1进行了仿真。仿真结果表明,该改进算法可明显提高节点定位精度,并且能有效降低网络通信量。 Based on the research of traditional DV-Hop 3D localization algorithm,this paper presents a new localization algorithm for wireless sensor networks.The new algorithm sets a threshold parameter of hops to reduce communication cost in the first stage,and the optional average hop size was used instead of the fixed average hop size in the second stage to calculate the distance between unknown nodes and anchor nodes.Simulation was made by using Matlab7.1,the results of the simulation show that the improved DV-Hop 3D algorithm can obviously improve the localization accuracy of the unknown nodes and also reduce communications traffic effectively.
