Abstract：A performance analytic model for underwater acoustic networks is presented in this paper. This model is established by the characteristic of underwater channel propagation and networking. Numerical simulation results indicate that the bandwidth efficiency of peer-to-peer network and centralized network both are relative with network scale, the workload of node, interval between nodes and transmitted power. The appropriated networking and protocol design can improve the communication performance of underwater acoustic networks, achieve optimum nodes’ interval for bandwidth efficiency. Research results in this paper can be use to guide application for underwater acoustic networks.
