摘要:

针对信号传输的不规则性对定位算法的影响进行了分析,选取定位算法中的APIT算法作为研究对象,APIT算法适用于信标节点比率比较高的场合。通过运行一组仿真实验,获得了该算法在4种传播模型中的定位性能对比表。从仿真结果分析可以看出,随着通信的模型的不规则度DOI增加,定位误差以及网络连通度也保持增长态势。

Abstract:

In this paper,we explore the impact of radio irregularity on localization algorithm.We take APIT algorithm from the localization family and analyze the impact,APIT require a higher beacon-to-node ratio than others to achieve a given level of accuracy.We run a set of simulation experiments to obtain the localization performance chart of the algorithm in each of the four different propagation models.We observe that with the increase of DOI(degree of irregularity) values,the localization error and network connectivity keeps increasing.

Key words: APIT algorithm;propagation models;analysis of the performance
