Underwater wireless communication has become very important parameter nowadays. our earth is almost fully equipped by water, about seventy-one percent of earth's surface is water. As the world has raised their technology level up to the top, underwater wireless communication has become fastest growing fields. our technology will grow up rapidly if we are able to give more information of underwater world to the real-time world, this is only possible by wireless communications and systems. Underwater communication is more complex and harsh wireless communication, as it is affected by many things such as marine condition, pollution, noise, limited bandwidth and many more. so, it's very important to control such parameters which would not affect again. The need for underwater wireless communications exists in various applications such as human communication underwater, disaster detections, monitoring the pollution in environmental systems, video and image transmission to the real-time world, the collection of data from water stations and many such discoveries can be obtained. and thus, underwater wireless communication has played the most important role in this competitive world.
