摘　　要：利用无线信号强度实现了煤矿安全监测无线传感器网络(WSNs)节点间的自定位,提出了一种新的节点定位算法,介绍了算法的基本原理和实现方法。该算法不需要任何额外的硬件支持,节点间通信开销少。仿真结果表明:所提出的算法可以有效地提高WSNs节点的定位精度。The self-localization between network nodes of wireless sensor networks in coal mine safety monitoring is realized by using wireless signal intensity, a new kind of nodes positioning algorithm is put forward, the basic principle and implementation method of the algorithm are also introduced. This algorithm doesn＇t need any excess hardware support, and the expense between nodes is low. Simulation result shows the algorithm proposed can improve the location precision of wireless sensor nodes efficiently.
