摘　　要：目标定位是无线传感器网络应用领域中一个重要的问题,是进行目标跟踪的前提和基础。节点呈栅格部署的无线传感器网络由于拓扑结构特殊,在目标定位应用领域具有独特的优势。本文基于栅格部署的无线传感器网络,提出了栅格预置点目标定位方法,通过设定和选择合适的栅格预置点进行目标定位。仿真实验和实际测试实验表明,该方法在定位准确性和实时性方面较先前的单层栅格定位和双层栅格定位都有较大幅度的提高。Target localization is an important issue in the field of wireless sensor networks applications, which is also the prerequisite and basis for target tracking~ Because of the special topology structure, grid-deployed wireless sensor networks have unique advantage in target localization. Based on the grid-deployed networks, this paper proposed a preset-points localization method by setting and selecting preset-points in grids. Simulation and real system test results showed that compared with single- level grids localization and double-level grids localization, this method did better in the capacities of accuracy and real-time.
