Underwater sensor network (USN) enables various services implemented over terrestrial wireless sensor network previously and underwater robot control service is one of the applications of USN. For wirelessly controlling an underwater robot, development of an underwater acoustic modem for transmitting robot control frame as well as analysis of the robot control protocol should be carried out properly...
In this paper, the authors design and implement an acoustic modem for UWSN, improved in the sense of performance and efficiency. The proposed modem is equipped with one transducer shared at transmitter and receiver to increase hardware efficiency. We also verify our modem by making experiments in a water tank, a pond and the ocean with various data rates at various communication distances, and observe...
Recently, the importance of underwater wireless sensor networks (UWSN) has been grown for the applications such as underwater environmental monitoring, oceangraphic data collection, tactical surveillance and disaster prevention. In this paper, we design and implement an underwater modem by utilizing a general-purpose digital signal processor star kit (DSK) which embeds Texas Instrument TMS320C6416...
We have designed and implemented an underwater modem using a general-purpose waterproof ultrasonic sensor which is appropriate for UWSN owing to its low-power property and extremely low cost. As a succeeding work, we will try to improve the performance of the underwater modem in terms of data rate and communication distance by adopting state-of-art transmission technology.
Underwater sensor networks (USN) for ocean development and disaster prevention have been emerged as one of interesting research topics recently. Since low-power, high-speed and inexpensive communication modem is a prerequisite for deployment of USN, in this paper we design and implement an underwater modem by utilizing general-purpose waterproof ultrasonic sensors. Also, we make some experiments in...
