Low-Cost Underwater Wireless Communication System Development Using Piezo-Ceramic Transducer

Abstract

In recent years, the need for reliable, short-ranged underwater wireless communication has been proliferated because of the surge in underwater exploration. Underwater Wireless Sensor Networks (UWSN) can be used in vehicles and sensors to perform collaborative monitoring and data collection task. Due to the high density and contamination, limited bandwidth, high propagation delay, media access control, and power constraint underwater communication is a very challenging task. Researchers developed different research methodologies to overcome this problem. In this paper, an acoustic communication-based system is proposed by using Piezo-Ceramic transducers and practically developed. The acoustic wave can travel easily in water without much attenuation. Piezo-Ceramic transducer creates vibration according to the electrical pulses and does not need much modification of real data signal. This paper describes a wireless low-cost acoustic system for underwater communication. The system is built with some filters and amplifiers and power booster circuits. Finally, a cost effective underwater communication system is proposed that has been successfully implemented on a submarine bot.
