摘要
在测距的基础上,提出一种基于三角几何运算的无线传感器网络节点定位算法。该算法利用与未知节点相关的一边两角,通过空间三角几何运算,实现对未知节点的定位。对该算法的性能进行分析,并在此基础上提出一些改进的措施。仿真结果表明:该算法可以达到较高的定位精度,能够满足三维空间中对未知节点的定位需求。
On the basis of distance measurement, a WSNs node localization algorithm based on geometric operation is put forward. The algorithm uses one side two angle which are related to unknown nodes to realize the localization of the unknown nodes, by space triangle geometric operation. To analyze the performance of the algorithm, and put forward some improvement method. The simulation results show that this algorithm can achieve high localization precision, and can satisfy the localization demand of the 3D space to unknown nodes.
