我们提出了一个方案，使用从商业RF传感器接收到的信号强度来确定传感器在水下的位置。该方案能给出准确的位置信息，更新速度快，但受限于传感器距离较短，存在信号识别问题。基于基础设施的定位和为RF传感器分配频带的方法可以是克服这种范围限制而不损失更新速率或位置精度的解决方案。RF传感器模块用作AN，并且通过其通道分配容易地识别。为了验证所提出的定位方案，我们组织了一个实验环境，并进行了重复实验，以跟踪移动的节点和固定节点在二维环境中的位置。实验结果表明，可靠的定位精度与快速采样率，并证明了定位的可行性，利用电磁波衰减。
We propose a scheme that uses the signal strength received from commercial RF sensors to determine the position of a sensor underwater. The scheme can give accurate position information and has fast update rate, but is limited to short sensor range with the signal identification problem. The infrastructure-based localization and a method that assigns frequency bands to RF sensors can be a solution to overcome this range limitation without loss of update rate or position accuracy. The RF sensor modules are used as ANs, and are easily identified by their channel assignments. To verify the proposed localization scheme, we organized an experimental environment and performed repetitive experiments to track the positions of mobile nodes and stationary nodes in 2D environments. The experimental results showed reliable localization accuracy with fast sampling rate and demonstrates the feasibility of localization that exploits EM wave attenuation.
