Underwater Wireless Communication with Acoustic Waves

Underwater wireless communication Communication between any two entities can be wired or wireless. The concept of wireless technology began in 1923. As we all know, 70% of the earth is covered with water. We need to develop a wireless network that can also function underwater. The concept of sound wave appeared here. Sonic waves work better underwater. It can also move underwater for a long distance, it is faster than radio waves. The concept of underwater wireless communication is a major finding in the field of wireless communication.

Of the three types of waves, acoustic waves are used as main carriers for underwater wireless communication systems because absorption is relatively low in aquatic environments. We begin discussing the physical basis and significance of using sound waves as wireless communication carriers in an underwater environment. Propagation speed: The very slow propagation speed of sound in water is an important factor for distinguishing it from electromagnetic wave propagation. The speed of sound in water is determined by the temperature of water, salinity, pressure (it is directly related to depth). The general sound speed in water near sea level is about 1520 m / s. It is 4 times faster than the sound speed in the air, but it is 5 orders of magnitude smaller than the speed of light. The speed of sound in water increases with increasing water temperature, salinity, and depth.

In this article I will explain the physical basis and use of sound waves as a wireless communication carrier in an underwater environment and then the overview of the underwater wireless communication routing protocol will be described in section III. In the fourth section we discussed two network architectures of UWSNS. Section 5 describes the acoustic modem technology and details the Link Quest's cutting-edge acoustic modem. Section 6 compares the ground sensor with the mobile UWSN, and Section 7 compares various applications. UWC Finally, we will summarize the thesis in chapter 8, then summarize the references.

Sonic waves work better underwater. It can also move underwater for a long distance, it is faster than radio waves. - Resonance and sound ... Because physics and music are media of music, most of the physics of music is physics of sound. It is important to remember that sound waves are compression waves. You can imitate the compression wave by stretching the tights (you have tight feet?) And finally tap the coil with your fingers. Sonic waves are not like waves on the ocean or stretched ropes. Take the tuning fork (You have a tuning fork.)
