  Abstract

In this paper, we implement a single hop short-range underwater acoustic network (SrUANet) which has communication range up to 200 m and a maximum transmission data rate of 100 kbps. The SrUANet consists of three software modules: 1) linux-based network protocol software that provides functions of the upper layer, including the scheduling algorithm for time-division multiple access, which can overcome underwater network throughput degradation, 2) software for the interface between the physical layer and the upper layer, 3) window-based graphic user interface software for the control and monitoring of the upper layer. A three-step verification test is performed on the SrUANet. The first step is to verify the integrity of the network protocol software by implementing a physical layer emulator that allows the network protocol software to operate independently of the real physical layer. The second step is to develope a network node by integrating the physical layer and the upper layer and perform laboratory test using a channel simulator that provides a network test environment similar to the real sea test. Finally, we give test results at south sea for short message, image and continuously repeated data. The SrUANet might be applied to wireless networks for multiple underwater robots.
