如何使用 Inet4.0 在 Omnet++ (5.6.2) 上模拟 Zigbee 协议？

如何解决如何使用 Inet4.0 在 Omnet++ (5.6.2) 上模拟 Zigbee 协议？

简介

我正在尝试在空中网络中模拟一个简单的 zigbee 通信。 Omnet++ 已经有一个仅定义物理层和 MAC 层的 IEEE 802.15.4 标准示例。我认为为了创建 Zigbee 网络，我应该定义网络层和应用层。

问题陈述

话虽如此，我目前正在修改 IEEE 802.15.4 代码。我有一个协调器、路由器和一个终端设备。我希望（协调器和路由器）和（路由器和终端设备）相互交换数据包（双向）。我得到的结果不是我所期望的。

我认为我的可视化代码和 xml 星形拓扑文件有问题。我是 omnet++ 的新手，所以我不太确定我应该如何解决这个问题。
