Marine science and Internet of Underwater Things applications rely significantly on collecting data from underwater sensors. Data collection using long-distance acoustic communications consumes a lot energy in sensor nodes, which are powered by batteries. To achieve low-energy consumption, we can use the autonomous vehicle (AUV) to move close nodes exploit short-range high-rate communications. Most existing AUV-based schemes consider scenarios having knowledge node positions, where cruising...

Signal detection is a crucial process for communication systems, and molecular (MC) no exception. Current research on signal in MC focuses either model-based detectors or data-driven detectors. In contrast, our work investigates the integration of both schemes. By incorporating prior knowledge from scheme, neural network structure can be redesigned, significantly mitigating impacts inter-symbol interference inter-link multiple-input multiple-output (MIMO) systems. The feasibility such an...
Ocean big data is becoming a future trend of the Internet Underwater Things (IoUT). wireless sensor networks (UWSNs) technique promising method to realize ocean data.
