水下无线传感器网络中基于三角形的定位方案OA

In order to improve the positioning accuracy of Underwater Wireless Sensor Network(UWSN)nodes,a zone-par-titioning-based localization(ZPL)algorithm is proposed based on triangle geometry theory.The algorithm uses the triangular area formed between two anchor nodes and the node to be located,takes the ranging result as the side length,and iteratively refines the area according to the geometric theory to achieve position estimation.In the process of zone partitioning iterative positioning,linear algebra operations with low complexity are mainly used to improve the computational efficiency.After sim-ulation comparison and analysis,the ZPL algorithm has more stable performance than the traditional positioning method,ef-fectively increases the number of locatable nodes,and reduces the positioning error.
