摘要
通过在每个无线传感器节点配置一个超声波发送接收装置,然后利用超声波的时延估计算法计算出探测区域内定位节点的位置状态信息;文章利用无线传感器网络设计一个基于超声波的定位系统,先通过超声波到达不同参考节点的时延估计出定位节点的位置,然后再利用插值算法计算出定位节点的准确位置,最后利用MATLAB仿真平台对设计的算法和传感器网络进行仿真;仿真结果表明利用超声波的定位明显比传统测距的三角定位算法精确,定位误差为0.010321。
Deposing each wireless sensor node an ultrasonic receiver, then using ultrasonic detection to estimates the delay and calculate the position of the target node area status information. In this paper, a wireless sensor network positioning system based on ultrasonic . First, using the delay of the different reference nodes to the target, then estimated the position of the target. Second, using interpolation algorithm calculate the exact location of the node localization. Last, using MATLAB Simulation Platform simulate the algorithms and sensor networks. Simulation results show that the positioning of ultrasonic distance measurement over traditional triangulation algorithm for accurate, Positioning error is 0. 010321.
