Abstract:
In recent years, terrestrial wireless sensor networks and Internet of Things (IoT) technologies have developed rapidly. However, due to the limitations of Electromagnetic (EM) signal propagation in water, there is less development and advancement in the underwater wireless sensor networks domain. As part of the IMPAQT project, a novel wireless underwater telemetry platform using acoustics has been proposed. This telemetry platform has the potential to replace the underwater sensors cables and provide a wireless method to collect and transmit a variety of environmental sensor data under water. The proposed platform system architecture consists of several ultrasonic transmitter nodes and a gateway buoy as a data aggregator node to transmit the data from the sensors to the cloud for analytics to be carried out. Transmitter nodes will read the attached sensor data and transmit it to the gateway buoy. The gateway buoy will send the collected data to a data management system using a Long Range (LoRa) communication link. The next generation IMPAQT Transmitter node developed is a compact, low-cost, low-power acoustic transmitter node that has an external sensor interface to receive data from attached sensors is described in detail in this paper. In addition, the potential for short-range EM-based underwater LoRa communication is evaluated and described.
