可能是因为您的项目没有包含必要的头文件或库文件。请确保您已经正确安装了 ns3,并且在项目中正确包含了相关的头文件和库文件。您可以在程序开头添加以下语句来包含 ns3 的头文件:
```c++
#include "ns3/core-module.h"
#include "ns3/network-module.h"
#include "ns3/wifi-module.h"
```
如果问题仍然存在,请检查您的编译器是否能够找到相关的库文件,并且在编译时正确链接这些库文件。

```
该示例包括创建节点、设置WIFI通道、创建移动模型、设置IP地址、创建UDP应用程序和配置跟踪等步骤。其中,通过设置不同的参数,可以模拟不同的WIFI性能情况。
