SPL07: Underwater monitoring and networking such as internet of things underwater

The Internet of Underwater Things (IoUT) is a novel class of Internet of Things (IoT), and is defined as the network of smart interconnected underwater objects. IoUT is expected to enable various practical applications, such as environmental monitoring, underwater exploration, and disaster prevention. With these applications, IoUT is regarded as one of the potential technologies toward developing smart cities. To support the concept of IoUT, Underwater Wireless Sensor Networks  have emerged as a promising network system. Underwater Wireless sensor networks are different from the traditional Territorial Wireless Sensor Networks , and have several unique properties, such as long propagation delay, narrow bandwidth, and low reliability. These unique properties would be great challenges for IoUT. IoUT is defined as “the network of smart interconnected underwater objects”.
The underwater narrow bandwidth communication most rely on short range ultrasound. High bandwidth channels most rely on laser or visible light high bandwidth communication channels.

We would like to establish visible light communication link and test it in blue part of spectrum to provide necessary data for calculation of channel capacity. We would like to test visible light communication link based on different modulation techniques and test it regarding different rate of water pollution. Short range, under 25 m is considered.
