摘要: 现有煤矿无线传感器网络节点定位存在定位精度差、功耗高等问题,提出一种基于信标节点规则部署的煤矿井下无线传感器网络节点三维定位算法,根据井下巷道特征成对部署信标节点,在定位估算时先将信标节点投影到与未知节点同一高度的水平面,再利用三边测量法进行平面定位,然后结合未知节点与信标节点的高度差即可实现三维定位。理论分析和仿真结果表明,该算法具有计算量小、通信量小、定位精度较高以及稳定性较好等特点。

Abstract: Most of the existing algorithms for Wireless Sensor Networks (WSN) localization in underground coal mine have problems of low accuracy and high cost. A new 3D localization algorithm was proposed for underground coal mine based on the regular deployment of beacon nodes. First, the beacon nodes were deployed according to the characteristics of the underground tunnel; second, the beacon nodes and unknown node were projected onto the same high level while doing location estimation; third, 2D position was calculated by trilateration; at last the 3D position was obtained by means of combining the height difference between unknown nodes and beacon nodes. The theoretical analysis and simulation results show that the algorithm is of less calculation, low communication, higher positioning accuracy and good stability.
