Underwater Acoustic Communication Network's MAC Protocol and Opnet Network Simulation
In this thesis,the authors refe to underwater communication network MAC(Media Access Control) layer multiple access technology and put forward TDCDMA(TDMA and CDMA),moreover, the TDCDMA protocol is simulated in Opnet software under the condition of underwater acoustic channel.Some defects are found from simulation results, so TDCDMA protocol is optimized and simulated in Opnet again, comparing the two results show that optimized TDCDMA protocol can improve network throughput.
