Abstract

As one of the most important basic supporting technology of WSN, wireless sensor network positioning technology has an indispensable role. Different positioning algorithms have different strengths and weaknesses, in order to achieve high positioning accuracy and large node coverage, this paper proposes hybrid positioning algorithms of APIT and DV-HOP based on the analysis of various basic algorithms deeply. To improve the positioning accuracy and the rate of node coverage, the new algorithm of using angles to determine the exact location of unknown nodes was approved. Then the algorithm of APIT is adopted to the unknown nodes in the triangle with positioning error from 14.7215 meters to 3.2348 meters, as well as the DV-HOP weighted with the minimum hops to localize the rest unknown nodes with positioning accuracy increased by 49%. MATLAB simulation proved its effectiveness.
无线传感器网络中基于APIT和DV-HOP的混合定位算法
无线传感器网络定位技术作为WSN最重要的基础支撑技术之一,具有不可或缺的作用。不同的定位算法各有优缺点,为了实现高定位精度和大节点覆盖,本文在深入分析各种基本算法的基础上,提出了APIT和DV-HOP的混合定位算法。为了提高定位精度和节点覆盖率,提出了利用角度确定未知节点准确位置的新算法。然后对三角形中定位误差在14.7215 ~ 3.2348 m的未知节点采用APIT算法,并对其余未知节点采用最小跳数加权的DV-HOP算法进行定位,定位精度提高49%。MATLAB仿真验证了其有效性。
