摘　　要：通过对水声对抗环境下网络通信的特征进行分析,利用OPNET网络仿真工具搭建起由异构网关连接的舰载有线网络和水下无线网络所构成的异构网络结构,然后在异构网关中分别采用先进先出(FIFO)和轮询(RR)两种不同调度算法,来对比研究水声对抗环境异构网络的实时性能,从而优化网络性能,使水声对抗异构网络具备更加可靠、高效的传输性能,进而提供更好、更稳定的网络服务。Based on the analysis of network characteristics in the underwater acoustic countermeasure environment,the heterogeneous network structure which is made up of shipboard network,wireless network and heterogeneous gateway is established by network simulating tool called OPNET. And there are two different scheduling algorithms in the heterogeneous gateway： First In First Out（ FIFO） and Round Robin（ RR）. So the real-time performance of the heterogeneous network with two different scheduling algorithms can be comparatively analyzed. Thus the network performance can be optimized. In addition,underwater acoustic countermeasure heterogeneous network will have more reliable and efficient transmission performance and will provide better and more stable network services.
