1.1 OMNeT++为何物？ OMNeT++是一款面向对象的离散事件网络模拟器，可以实现的功能如下： .无线电通信网络信道模拟 • 协议模拟 • 模拟队列网络 • 模拟多处理器和其他分布式硬件系统 • 确认硬件结构 • 测定复杂软件系统多方面的性能 • 模拟其他的任何一种合适的离散事件系统 一款OMNeT++模拟器包括一些分层次的嵌入式模型,嵌入式模型的深度是无限的,即允许用户在模拟环境中绘制实际系统的逻辑结构.各模块通过信息的传输进 行通信,其信息可以包括任意复杂的数据结构,各模块均可以通过门或者线路直接发送信息给目标点或者也可以通过预先的路径进行传输. 各个模块可以有自己的参数集,参数集可以被用于定制模块行为,或者可以用于确定模拟拓扑图的参数. 。。。。。。
