摘要

无线传感器网络中锚节点分布情况在很大程度上影响未知节点定位的精度

但目前对均匀性的分析相对较少

针对这一问题

对锚节点分布与无线传感器网络定位算法性能之间的关系进行全面分析。首先提出了锚节点均匀分布的相关概念

并设计建立了相应的网络系统模型

然后对质心算法、DV-Hop算法、最小包容圆算法性能与锚节点分布之间的关系进行了仿真实验。结果表明:锚节点的分布情况对所有定位算法均有影响

其中质心算法对锚节点均匀性最敏感

DV-Hop算法次之

最小包容圆算法对锚节点均匀性最不敏感

分析结果对无线传感网络实际应用具有指导意义。

Abstract

Uniformity of anchor nodes distribution has a very important impact on localization precision in wireless sensor networks（ WSNs）

but related research is limited

in order to solve this problem

relationship between anchor node distribution and localization performance of WSNs is analyzed. Firstly

related concept of anchor nodes uniformly distribution is proposed

and corresponding network system model is designed and set up

then simulation experiments are carried out to test relationship between performance of centroid algorithm

DV-Hop algorithm

smallest enclosing circle algorithm and anchor node distribution. Results show that all localization algorithms are effected by anchor node distribution

centroid algorithm is the most sensitive to uniformity of anchor node

the next is DV-Hop algorithm

smallest enclosing circle algorithm is the most insensitive to uniformity of anchor nodes

the analysis results has guiding significance for applications of WSNs.
