水下传感器的一个问题是如何有效地将节点收集的大量数据传输到诸如水下航行器的询问平台。在节点和车辆之间建立物理连接通常是不切实际的，这意味着声学或光学无线解决方案。对于大量的数据，水下光无线的高带宽是一个优势。一个小的，低成本的平台，以证明水下传感器节点的光无线通信接口的潜力。为了提高无线光通信的可靠性和鲁棒性，采用了数字信号处理和纠错技术。该系统在3米和7.7米的水箱中以5Mbps进行测试，通过添加Maalox控制水的浊度。
One issue with underwater sensors is how to efficiently transfer large amounts of data collected by the node to an interrogating platform such as an underwater vehicle. It is often impractical to make a physical connection between the node and the vehicle which suggests an acoustic or optical wireless solution. For large amounts of data, the high bandwidth of underwater optical wireless is an advantage. A small, low-cost platform to demonstrate the potential of an optical wireless communications interface for underwater sensor nodes is demonstrated. To enhance the reliability and robustness of the optical wireless communication digital signal processing and error correction techniques are used. The system was tested in 3 and 7.7 meter tanks at 5 Mbps with the turbidity of the water controlled by the addition of Maalox.
