Thus, a considerable amount of research has been conducted concerning ways to utilize CS to gather data in WSNs. The CS-based data-gathering schemes in [9–11] obtained the member node readings utilizing fixed routing, in which ordinary nodes forward compressed data to the static sink node ...
Inspired by the above research, an AUV is developed for plateau hydrological data collection. The AUV is small and lightweight so that it is easy to deploy and operate. It has the performance of a torpedo-shaped AUV and the capability of hovering for long autonomy in shallow water (100 m...
