问题描述
我正在尝试在 Omnet 上模拟 WSN,因为我希望它是无线的,所以我选择了 Inet 框架.
I am trying to simulate a WSN on Omnet and since I want it to be wireless, I chose the Inet Framework.
现在我需要个性化发送消息的内容,但我找不到这样做的方法.
Now I need to personalize the Content of the Messages sent but I can't find a way to do so.
有人可以帮我吗?我在 unser 手册等中找不到任何内容.
can anybody help me with that? I can't find anything in the unser Manual etc.
谢谢!
推荐答案
这取决于什么是消息"以及您想从哪个模块发送它.如果您正在创建/测试应用程序协议,那么您可能需要创建新的 .msg 文件来描述您的消息结构.
It depends on what is "the Message" and from which module you want to send it.If you are creating/testing application protocol then you might want to create new .msg file which describes the structure of your message.
INET 的文档中有一节是关于处理数据包的https://inet.omnetpp.org/docs/developers-guide/ch-packets.html#representing-packets
INET's documentation has a section on working with packets https://inet.omnetpp.org/docs/developers-guide/ch-packets.html#representing-packets
.msg
文件看起来像这样:
cplusplus {{
const B YOUR_APP_HEADER_LENGTH = B(6);
}}
class YourAppHeader extends FieldsChunk
{
chunkLength = YOUR_APP_HEADER_LENGTH;
int someField;
bool someBit;
};
然后在你的 C++ 代码中
then in your C++ code
Packet *packet = new Packet();
const auto& payload = makeShared<YourAppHeader>();
payload->setChunkLength(B(<someValue>));
payload->setSomeFiled(<intHere>);
packet->insertAtBack(payload);
//and then send it
