摘要

针对无线传感器网络定位的要求

将传统的近似三角形内点测试（APIT）算法与几何质心算法结合

提出了一种全新的无线定位算法。先利用已知节点构成的内点三角形集合约束待定位节点

再通过约束三角形的接收信号强度指示（RSSI）权重几何质心估计待定位节点的位置

通过对多个约束三角形的质心坐标求平均定位未知节点。对于在约束三角形集合之外的少数待定位节点采用改进的DV-Hop算法求坐标

通过Matlab仿真证明:算法的精度相对于APIT算法得到了提高

具有一定的实用价值。

Abstract

Aiming at positioning requirements of WSNs

a new kind of wireless localization algorithm combining traditional APIT and geometric centroid algorithm is given.Use set of inner point triangles formed by known nodes to restrain nodes to be positioning

then estimate its location by restraining RSSI weight geometric centroid of triangle

and the locations of unknown nodes will be confirmed by averaging all the coordinates of these centroides.For some few unknown nodes which are out of these restrain triangles can be confirmed by modified DV-Hop algorithm to get coordinate.Matlab simulation shows that the precision of this algorithm is improved compared with APIT algorithm

and it has practical value.
