| 摘 要： | 在各种无线传感器网络应用中,无线传感器节点的精确定位非常关键。在阐述了节点定位问题的基础上,分析了三种典型节点定位算法:质心法、不定形(Amorphous)法和蒙特卡罗法,然后通过仿真实验对算法性能进行对比,研究节点密度、节点速度和采样个数等因素对定位性能的影响。实验结果表明,蒙特卡罗法的误差最小,且在锚节点密度大于1,未知节点密度大于6,取样个数超过50时达到最佳定位性能。

| Abstract: | Wireless sensor nodes localization is crucial for wireless sensor network applications.First,this paper described the localization problem,and then discussed three typical localization algorithms: centroid algorithm,amorphous algorithm and monte carlo algorithm.Finally,simulation experiments were carried out to compare the performance of three algorithms,and study the performance change of these algorithms with node speed,node density and sampling amount.Simulation results show that the error of monte carlo... |
