Underwater acoustic network in 3D environment can be divided into the surface of water, the middle of water, the bottom of water for monitoring. To analyze the performance of underwater acoustic sensor network in the presence of interference, a hierarchical architecture of underwater acoustic sensor network is designed for nodes deployment issues of the bottom of water monitoring area. Assuming that the underwater monitoring sensors and the collectors in the area are respectively operated in different layers, through the experiment, the relationship between the SNR(Signal to Noise Ratio) and the optimal operating frequency is analyzed, under different distance between nodes of cases. The experimental results show that it is rational and feasible when the collector layer and sensor layer adopt different optimal operating frequency for communication. It can ensure normal operation of the network and avoid cross interference effectively.
