(. Under the premise of uniform distribution of underwater network nodes/points, the underwater communication channel is simulated by connecting transmission attenuation and ray models, and the end-to-end uniform bit error rate (BER) and network node/ Connections between point distribution densities. Moreover, through the MonteCarlo simulation method, the MFSK communication method is selected between the single-hop links, and the connection between the network communication performance and the node/point distribution density is simulated.)
