Research on Robotic Fish Swarm Network Technology Based on Underwater Acoustic Communication

Ocean area accounts for more than 70% of the total area of the earth, and underwater space is complex. The ocean study, in aquaculture, resource exploration, and military aspect is of great significance. According to the length to width ratio of crucian carp, this paper designs a robotic fish that integrated control system and underwater acoustic communication machine. Then the essay constructs a multi-level marine Internet of Things based on the robotic fish. Besides, the marine Internet of Things includes three-dimensional network topology, and compose of bionic robotic fish with positioning and underwater communication functions. The study of robotic fish and marine Internet of Things are to better observe marine life and seabed space, reduce the cost of manual detection, and improve the ocean observation efficiency.
