摘要
在无线传感器网络定位中,距离定位机制受无线传感器设备功耗、价格和硬件限制及对定位精度的要求,距离定位机制比较容易实现的解决方案。介绍了超声波传感器定位的原理,提出了基于传感器数学模型的目标定位方法,在此基础上建立基于超声波的目标定位系统,最后分析了超声波传感器定位中存在的问题。
The Range_based mechanism's assumed as a cost-benefit solution to the Wireless Sensor Network due to the power,the price of equipment and the requirement to location accruracy. And It a quite easy relozation solution. The location Algorithm of a Range- based mechanism of Untrasonic location algorithm was introduced in the paper. Then mathematical model of location system based on untrasonic were built. Al last the problems of untrasonic sensor location were anlyzed.
