[英]how to add a new application module in wireless host in omnet ++
我的問題是這樣的:我在omnet ++中創建了一個名為my_app的簡單模塊的自定義主機,請參見圖1 。 我希望該模塊的行為類似於生成消息的應用程序,並且在收到來自較低層的消息時也會得到通知。 當我在網絡中添加主機並運行模擬時,出現以下錯誤。 見圖2
這是我的c ++文件(my_app.cc和my_app.h)`
#ifndef __MYAPP_MY_APP_H_
#define __MYAPP_MY_APP_H_
#include <omnetpp.h>
using namespace omnetpp;
/**
* TODO - Generated class
*/
class My_app : public cSimpleModule
{
int type;
protected:
virtual void initialize();
virtual void handleMessage(cMessage *msg);
};
#endif`
my_app.cc`
#include "my_app.h"
Define_Module(My_app);
void My_app::initialize()
{
this->type=par("type");
if (this->type==1){ // 1 for source
cMessage *msg=new cMessage("welcome");
send(msg,"out");
}
}
void My_app::handleMessage(cMessage *msg)
{
if (msg->arrivedOn("My_app_In"))
{
if (this->type==2){ // 2 for sink
delete(msg);
}
else
{
cMessage *msg=new cMessage("welcome");
send(msg,"My_app_Out");
}
}
else
{
error("Incorrect gate");
}
}
`,這是ned文件。 my_app.ned
`package myapp.simulations;
//
// TODO auto-generated module
//
simple My_app
{
parameters:
int type;
gates:
input My_app_In;
output My_app_Out;
}`

請幫我。 謝謝
很難說,但是我的猜測是,每次在項目中添加一些新類時,都必須重新生成Makefile。 還要確保將.cc和.h文件添加到“源”文件夾中。 (通常在OMNeT ++項目中默認為'src')。 也有可能您通過鏈接使用正在使用INET項目的單獨項目,並且以某種方式僅啟動了INET項目,而不是自己的項目。
