【摘要】：针对三维DV-Hop无线传感器定位算法存在定位误差较大的问题,提出了近似投影校正的无线传感器网络非测距三维定位算法。充分利用已有的地形特点,将经典的三维DV-Hop算法所求得的结果进行近似投影,尽可能投影到离地形表明较近的地方,大幅度减小了定位误差。用二维高斯分布密度函数模拟山头地形的场景中,相对定位误差为35%左右,较大幅度提高了定位精度,有较高的实用价值。
[Abstract]:Aiming at the problem of large localization error in 3D DV-Hop wireless sensor localization algorithm, a non-ranging 3D location algorithm for wireless sensor networks with approximate projection correction is proposed. The results obtained by the classical 3D DV-Hop algorithm are approximately projected to the point near the terrain, and the positioning error is greatly reduced. The two-dimensional Gao Si distribution density function is used to simulate the scene of the hilltop terrain. The relative positioning error is about 35%, which greatly improves the positioning accuracy and has higher practical value.
