Modeling and Simulation of Channel for Underwater Communication Network

According to the characteristics of underwater acoustic channel, Thorp experience formula is adopted in order to simulate seawater absorption properties, on the basis of which, the path loss is solved by means of simulation. A Wenz model is also improved so as to approach the noise model of underwater acoustic channel better. Furthermore, OPNET platform built-in propagation delay stage, a receiver power stage, background noise stage are improved in order to t underwater acoustic channel, and then basically realize an approximate simulation of the real channel. Mobile network model is designed and simulated with the simulative underwater acoustic channel added, and then the net-work performance influence of underwater acoustic channel characteristics is analyzed.
