| 摘 要： | 针对坑道内的人员和设备定位，提出了一种适用于锚节点固定，未知节点自由移动的移动传感器网络定位算法。基于MonteCarlo算法，采用牛顿插值法对未知节点的运动路径进行预测，并确立其位置的预测模型，根据提出的一种自适应无线电射程计算方法对预测位置进行滤波。减小了无线电射程的不稳定性对预测结果的影响。仿真结果表明：与其它几种具有代表性的移动传感器网络定位算法相比，本算法定位精度更高、对锚节点密度的要求更低。

| Abstract: | In view of the location of persons and equipment in a pit,this paper puts forward the localization algorithm of mobile sensor network for anchor nodes fixing and free movement of unknown nodes.Based on Monte Carlo,it predicts the moving path of unknown nodes and establishes the prediction model.Through wave-filtering the prediction position by the algorithm method of adaptive wireless radio range,the influence of the instability of wireless radio range on the prediction result is lessened.The emulation result shows that this algorithm,compared with other typical methods,is more accurate. |
