Omnet access method of another submodule error - no matching function for call to ‘check_and_cast(cModule*&)’
Well I figure out the problem. First thing I needed to add header file of mobility module in my current sub module to get the definitions. So I included- #include "MassMobility.h" #include "StationaryMobility.h" then in code I did following modification:- cModule* parentmod = getParentModule(); cModule* mobilitymod = parentmod->getParentModule()->getSubmodule("mobility"); MassMobility* massMobilityMod...
Node creation or apperance at run time in Omnet (INET)
The OMNeT++ User Manual has a section dedicated to this. According to this you don't need buildInside() and scheduleStart() when using createScheduleInit(). An example how this is performed can be seen in the Veins framework - more precisely in the TraCIScenarioManager. The important lines for you are probably: cModule* parentmod...
Differences between inet_aton() and gethostbyname() in C?
c,gethostbyname,inet,inet-aton
gethostbyname() is obsolete. You should use getaddrinfo(). inet_aton() only works for IPv4. Also, inet_aton() only convert a IPv4 notion (0.0.0.0) to int, getaddrinfo does DNS resolution....

Overriding Functions with omnet++
you have two versions of AODVRouting::handleMessage(cMessage *msg) function. One in AODVRouting.cc coming from #include "AODVRouting.cc" and one in your current file of which you have pasted the code but we don't know the name. Either remove #include "AODVRouting.cc" line from your current file or rename your class so it does...
How do I compare IP addresses in PHP as binary strings?
After much troubleshooting, I discovered the cause of this issue. When using the unpack function, I had used the format code "A4" which is for space-padded strings. This was causing anything ending with the number 32 to get treated as whitespace, which would then be trimmed. For example, after unpacking...

Changing model parameters by cPar in other module
Declaring your parameter as volatile should solve your problem. But for future reference I'll provide further explanation below Volatile vs. non-volatile: Here it depends how you want to use this parameter. Mainly via the .ini file you have two types of parameters: volatile and non-volatile. volatile parameters are read every...
How can I convert an IPv4Address to char in omnet++(inet)?
Judging by the definition of IPv4Address in the source code of INET v2.99.1, I would say that its str() method can provide the text representation as a std::string. If you need a char* you can call the string's c_str() method.
