| Abstract | Abstract: Various novel applications of underwater acoustic sensor networks have emerged or been proposed in recent years. As such networks are expected to remain in situ for long durations, multi-hop networking schemes are required for robust and energy-efficient data dissemination. These can be particularly challenging in the warm and shallow waters around Singapore. In addition, for meaningful interpretation of sensed data and to assist with network scheduling and data dissemination, accurate underwater localization, typically achieved through range-based methods, is needed. However, signal reflections from the sea surface or bottom, or from objects such as ship hulls and docks, can give rise to localization inaccuracies if falsely identified as the line-ofsight (LOS) and must therefore be identified. In this paper, we present our experiences in the design and testing of (i) a robust multi-hop underwater network for long-range sensing and (ii) a classification of time-of-arrival measurements to LOS and non-LOS to improve the accuracy of range-based underwater localization in Singapore waters. |
