本文以模拟一个移动无线网络为背景，使用一种功能强大的网络建模和仿真工具—OPNET，建立移动无线网络的仿真模型，并运行仿真，通过对误码率及吞吐量的查看，比较在两种不同类型的天线下，接收信号质量的不同，详细得出在采用有向天线模型时更有利于提高接受信号的质量。
首先，简要介绍了网络仿真背景、OPNET Modeler软件仿真的体系结构和建模机制。
然后对所要仿真的移动无线网络进行深入分析，对无线网络的特性以及无线网络的定义和优缺点做了简介，并且通过分析写出它的设计方案。
最后进行了仿真分析测试，通过仿真得出了当网络采用有向天线时比全向天线，在接受信号质量和网络性能方面都得到提高，为信号在无线传播环境下的优化提供了有效的依据。
机器翻得，自己再顺通一下哈 O(∩_∩)O~
Today, there are more and more people to pursue a wireless network, the flexibility that it can be much larger than the cable network in the out of the shackles of cable, the wireless network with high mobility features, as long as the wireless signal coverage in the scope equipped with a wireless LAN terminal equipment can move freely, while maintaining continuous network connectivity, so a wireless network compared to wired networks with better prospects for the development of, and experience to rely on simple network design has been developed can not meet the network and therefore in urgent need of a scientific means to reflect and predict the performance of networks, OPNET simulation software, the emergence of a better solution can be said that the technical difficulties in this regard.
In this paper, to simulate a mobile radio network as the background, the use of a powerful tool for network modeling and simulation-OPNET, the establishment
