Deployment efforts of underwater acoustic sensor networks have been impeded by the prohibitive monetary cost and high power consumption of existing acoustic hardware, which typically targets deep water long range communication. To address this issue, the authors propose software-driven underwater networks that rely on widely available speakers and micro-phones in electronic devices, coupled with software modems, to establish wireless acoustic communication links. The proposed acoustic communication system paves the way for cheap and easily deployable underwater acoustic sensor networks for marine monitoring applications with low data transfer requirements.
