The past few years have witnessed a significant progress in research of underwater acoustic networks. Some MAC and routing protocols tailored for underwater acoustic networks have been proposed. However, it is difficult and costly to build real underwater network systems as well as conduct field experiments, and most researches are based on theoretical analysis and simulations. To facilitate evaluating research work in real environment, we develop a testbed in Qinghai Lake based on Orthogonal Frequency Division Multiplexing (OFDM) modems and Micro ANP protocol stack. Based on the testbed, we conduct a number of tests including protocol evaluation and water quality monitoring of Qinghai Lake on real time.
