仿真是移动Adhoc网络研究的重要方法,仿真工具常用于新协议的设计和性能评估,以及大型复杂网络的构建和优化。文中详细介绍了OPNET、NS-2、GloMoSim/QualNet、OMNeT++的内部体系结构和对Adhoc网络的支持,最后总结了四种仿真工具的特点和性能。
Emulation is an important method for mobile Adhoc network research. Simulation tools are often used in the design and performance evaluation of new protocols and in the construction and optimization of large and complex networks. In this paper, the internal architecture of OPNET, NS-2, GloMoSim / QualNet, OMNeT ++ and the support of Adhoc network are introduced in detail. Finally, the characteristics and performance of the four simulation tools are summarized.
