Underwater Acoustic Networks(UWANs)

UWANs have been urgent topics needed to be addressed in the last few decades due to their key roles in many applications, for example, environmental monitoring, offshore exploration, oceanographic data collection, and disaster warning. However, compared with terrestrial radio communication channels, underwater acoustic channels are featured with large transmission loss, high ambient noise, severe multi-path echoes and rapidly time-varying characteristics. Nowadays, research on UWANs is still in full swing. We focus on the research of physical layer and medium access control (MAC) layer. In physical layer, we do some researches on long-range low-rate communication and short-range high-rate communication systems facilitated by deep learning algorithms and autonomous underwater vehicles (AUV). Meanwhile, we also develop the prototypes of the aforementioned systems. In MAC layer, we study on physical network coding (PNC)-based underwater acoustic MAC.
