Offshore wind turbine monitoring is crucial to reduce maintenance and operating costs of safety-critical components and systems, and to optimize the design of future wind turbines. Monitoring has four objectives: the acquisition of structural response data, local interrogation of collected measurement data, and wireless transmission of that data or analysis results to a underwater acoustic sensor networks (UASN). These sensing units require the design of dedicated UASN networking protocols. In this context, we implement the TDA-MAC protocol for data collection in UASN which needs any clock synchronization. The preliminary experimental results have successfully demonstrated the effectiveness of this MAC protocol on very low speed and long-range transmission devices.
