A moving underwater communication system with bio-inspired fish robots.

Recently, there has been large interest on short and medium range underwater communication systems for various applications. In this work, we investigate a moving communication system equipped with bio-inspired fish robots. A protocol stack encompassing physical layer, medium access control layer and network layer is designed for a packet-based hierarchical underwater acoustic communication and the related hardware is implemented. The developed components and system prototype are verified and evaluated in the Han River. Since this system provides high mobility and real-time monitoring service, it could be utilized for pollution monitoring and surveillance in rivers and oceans.
