基于OPNET的网络并行仿真实现

通信网络的应用越来越广泛其规模也越来越大.传统的基于OPNET的单机网络仿真在面对大规模的网络时由于受到计算机硬件条件以及软件性能的限制其仿真效率受到了一些制约。通过对OPNET软件做开发扩展其功能使之可以在多台计算机上并行运行,将一个大规模网络分散到两台或者两台以上的计算机上运行,使用WINSOCK和c 的动态链接库辅助完成多台计算机之间的通信,使得各台计算机进行协调联合仿真。最后通过仿真结果可以看出多台计算机分担了一台计算机的负荷提高了仿真效率。

Co-simulation Realization of Network Based OPNET

The application of network has attracted increasing attention and its scale becomes larger and larger. When the simulation of ad hoc networks is applied in large - scale network, based on traditional OPNET implemented on single computer, the efficiency of simulation suffers certain restriction due to the performance of the hardware of computer and the simulation software. In order to run OPNET on multiple computers in parallel and implement large - scale networks onto two or more than two computers, this paper extends OPNET software. By using the WINSOCK and C DLL file, it can help the communication among computers so that multiple computers can run the same simulation in parallel. Simulation results show that multiple computers share the load shouldered on single computer - proving the simulation performance.
