Underwater Wireless Communication System

-Water data communication is a potential technology to realize underwater communication. The experiment of underwater data communication in the laboratory is different with that in the real water environment because the physical scale is limited. In this paper, several kinds of agents are evaluated to change the coefficients of experimental water precisely. Then, seemed as criterion for the reliability of water recreation, the frequency domain characteristic of data communication through water channel in experimental water is measured and compared. The results show that the type and particle size of the agents will significantly affect its water properties, and the frequency domain component of the water communication signal will be affected by the agent’s concentration. By having a separate transmitter and receiver module in the water between the modules we can transmit the sea researcher’s biomedical conditions and interactions to the monitoring end available on the ship. The atmospheric conditions under the sea will be changing tremendously. It affects the sea navigators in too much trouble. It is difficult to monitor the health conditions of sea navigator after diving. Even if he dives below 20 meters his heart beat becomes uncontrollably changing. So even if his blood pressure lows dangerously it may leads to death. And there is no idea to save those navigators in those conditions. So here we propose a system to monitor heath conditions of a sea navigator while checking the heart beat reading while navigation. Using a communication system we can monitor a diving navigators heart beat even in ground. If we found his BP is lower in we can say him to enter the ground. So we can save the life of too many navigators. KeywordsUnderwater communication, wireless optical communication, scuba diving, heart beat sensor.
