Underwater Wireless Sensor Networks (UWSNs) and micro Autonomous Underwater Vehicles (μAUVs) enable diverse underwater monitoring and service applications; e.g., observation of water quality or identification of pollution sources. Reliable underwater communication for data transmission between sensors, μAUVs and base stations is required and typically acoustic. However, vessels and μAUVs produce noise, disturbing the acoustic data transmission. Additionally, in networks there is potentially a risk of packet interference. This paper discusses the resilience against noise and interference of low-power acoustic underwater modems in a network. We used the smartPORT Acoustic Underwater Modem (AHOI modem) to analyze signal processing and modulation schemes in a concrete case. The AHOI modem modem is a small, low-power and low-cost modem, which was developed for UWSNs and integration into μAUVs. Based on our findings, we evaluate the resilience in simulations and through real-world experiments in a marina. In general, the results are useful to design and simulate low-power acoustic underwater communication.
