Performance analysis of underwater acoustic FH-CDMA network

For underwater acoustic networks, the selection of MAC (medium access control) protocols will greatly affect the performance of the system. such as throughput and end-to-end delay. The ALOHA scheme takes advantage of simplicity, but the throughput is greatly decreased in the condition of high traffic and unstable channel. In this paper, we propose an alternative random access FH-CDMA underwater acoustic network. By using OPNET modeler wireless transceiver pipeline stages, we modeled the underwater acoustic channel. The network is consisted of eight nodes randomly deployed in sea with battery powered modem. The network models and simulation result are presented.
