Abstract

An emerging field is underwater communication being a developing field of research as of now. Which is an chief aspect in foreseeing the climatic conditions accurately. When compared to aerial communication, Underwater communication appears to be more taxing as water is non transparent and blurred to electromagnetic radiations excluding the visible region. In visible region, factors such as suspended sediments and the aquatic life affects the penetration of light. It may penetrate only up to few hundreds of meters in clear water and in turbid waters, penetration is even less. A component like Inter-symbol Interference (ISI) is introduced due to underwater communication being affected by multipath fading. Underwater Communication involves several knacks for the benefit in the communication aspect. Acoustic technology is a burgeoning and mature technology which is employed for underwater communication systems for better efficiency and results. These systems are proficient for long distance communication, but have several limitations. To cope up with the limitations of acoustic communication, Optical communication is used whose wavelength lies in the visible region. This system is known for high data rate and low latency Several setbacks occur submerged, be it, plane accident, transport sinking etc. It is an insipid activity to locate the lost debris. Hence an underwater optical link is developed which identifies the lost debris along with several other under water ventures. In this project, a hybrid model comprising of acoustic as well as optical link is proposed. This hybrid model compensates the limitation of each of individual types of communication systems. The hybrid model is able to work in several unlikely conditions as related to the depth and clarity. The comparison between acoustic and optical technique is studied and the hybrid model is simulated by using MATLAB simulation and the responses are scrutinized. This simulated result can be observed in various applications including climate monitoring, military services and communication between the divers and the ship.
