摘　　要：MAC(Multiple Access)协议是水声通信网络的重要研究内容,利用OPNET网络仿真软件对ALOHA协议和MACAW协议下水声通信网络的性能进行仿真研究,分析比较这两种协议在不同业务量下的网络性能。仿真结果表明,在水声通信网络中,MACAW协议的性能优于ALOHA,但两者均可应用于低数据业务量网络中。The MAC protocol is the key research content of the underwater network.In this paper,we use the simulation tool OPNET to research performances of the ALOHA and MACAW protocols in the underwater network,and compare their network performances in different traffic,such as the average delay,the throughput and the energy consumed.The simulation results show that the performance of the MACAW protocol is better than the ALOHA protocol＇s in current acoustic communication underwater networks,but both of them can be used in the low traffic networks.
