摘要
目前的传感器网络节点定位的技术主要有基于测距的定位技术和无需测距的定位技术。本文重点研究了基于RSSI测距的交点质心定位算法。主要研究工作包括RSSI测距模型与模型参数优化方法的分析与研究、交点质心定位算法的实现、交点质心算法在室内环境应用的修正等。应用结果表明,修正后的定位算法可在一定程度提高定位精度。
The location techniques for WSN can be divided into two categories： range-based approaches and range-free approaches. This paper focuses the investigation on the RSSI range-based algorithms using centroid calculation method. The main research includes the technology of distance measurement based on RSSI, parameter optimization to distance measurement model, centroid calculation localization and the refinement method of this algorithm. The experimental results show that the refinement algorithm can improve the accuracy of positioning to some extent.
