基于OPNET的地域通信网网络仿真研究

摘要

针对无线通信情况下地域通信网中心交换机节点问的通信质量，采用模块化的方法描述节点对象的行为并对节点进行建模，通过OPNET网络仿真工具对地域通信网各网络节点的仿真模型以及组成各节点的进程模块进行设计实现，结合地域通信网的一个实例，得出了节点受不同干扰情况下的全局数据业务丢包率和话音业务呼损率。%With communication quality of the center switch nodes of field communication network under wireless communication, using a modular approach to describe the behavior of nodes and node object modeling, through the OPNET network simulation tool, various nodes used in the field communication network were modeled, as well as thread modules which consist of the nodes, with a field communication network instance, arriving at a conclusion about total data traffic oacket loss rate and voice traffic call loss rate on condition of different interferences.
