Analyzation and Simulation of Underwater Laser Communication Based on Monte Carlo Mechanism

Underwater laser communication is an efficient communication method used in underwater environment. It has been used in many instruments to achieve high speed and wide band data transmission. In the presented paper, we simulate and analyze the affection on laser transmitting caused by random particle. We use Monte carol mechanism as tool to simulate a scenario of underwater laser communication. We focus on the relationship between density of different particles in water and the transmission area. Simulation results show that the output laser intensity under the rule of exponential distribution with the extend of communication area. We also find that although density is different the position of the strongest output light intensity is always at the second and the third line in simulation.
