摘要
节点定位对许多无线传感器网络的应用来说是非常关键的,提出了一种基于移动锚节点的无测距的节点定位算法。此算法建立在Monte Carlo定位算法基础之上,通过利用节点收集到的信息来加速算法中样本的选取,从而提高定位的精度和效率。仿真结果表明,此节点定位技术平均定位精度能达到0.2个通信半径,与其他类似定位技术相比,能够明显提高节点定位精度。
Localization is crucial to many applications in wireless sensor networks, This article presented a range-free anchor-based localization algorithm for wireless sensor networks that built upon the Monte Carlo Localization algorithm. We improved the localization accuracy and efficiency by making better use of the information a sensor node gathers and by drawing the necessary location samples faster. Simulation results show that localization accuracy of all nodes is one of fifth of communications radii.
