摘要
在几种常规定位算法分析基础上,提出一种新型分步定位法。通过利用待测移动节点最近的3个参考节点可快速计算出移动节点的坐标值,从而使定位算法更容易实现。实验结果表明,该方法在不增加任何硬件成本的前提下可显著提高定位精度并增强系统稳定性,同时降低环境噪声带来的测量误差。与常规定位算法相比,该算法可广泛应用于各种基于距离的定位场合。
Based on the analysis of the conventional location algorithms, a step by step location algorithm is pro- posed. The algorithm gets the position of mobile node by using three nearest reference nodes, which makes the distance-based location method be implemented easily. Experimental results indicate that the proposed algorithm can improve system stability and reach a relative location accuracy level without additional hardware cost. Mean- while the influence of environment noise has been decreased. Compared with the conventional algorithms, the step by step location algorithm has a flexible implementation for various distance-based location applications.
