Exploiting Feature for Localization in Mobile WSN

摘要: 在研究移动无线传感器网络特性的基础上,借鉴蒙特卡洛算法思想,提出一种利用移动无线传感器网络特性进行定位的算法(EFL).EFL算法把移动无线传感器网络的移动特性和低秩特性作为节点定位的约束条件以提高节点定位的精度.仿真结果表明,采用EFI算法,节点的定位精度有较大提高.

Abstract: This work deeply researches on the feature of mobile WSNs.On this basis and drawing on the MCL algorithm,we propose a exploiting feature localization algorithm(EFL).EFL uses the mobile feature and Low-rank feature as constraints in order to improve positioning accuracy.Simulation results show that EFL algorithm improves positioning accuracy of a node significantly.
