Hi,

Double click on mingwenv for windows environments.

Then you just follow doc in doc folder. If you are using windows, I still have a problem with INET framework 4. INET framework 3 is working properly.

Regards,

Thiha

How can I start omnetpp tool please anybody guide me?

[Ashi]

Did you mean to say how to open OmNet++ software?

[Ashika naik]

To open simulator you can type "omnetpp" as a command in the terminal if you are working on ubuntu.

Alternatively. Go to the ide folder inside omnetpp5.x -> ide . There will be omnetpp icon.

Hello

Once done with installation, I think working on omnet in ubuntu or windows it's almost same. But still if you wish to learn tutorials in windows environment, here's one video link for OmNet tutorial in windows. Hope it helps you.

Link : https://www.youtube.com/watch?v=GR8kb5dlIPA (OmNet first lesson lab01)

Thanks

For creating network and nodes within it, you can have look at page no. 12 of below attached pdf to get some idea.

Also you can try to view and create topology like star, grid etc .you can carry out following steps in OMNeT window:

File>New>Simulation>enter parent folder name>new folder name>click on next>Topology generation>click on on option star, grid..>select topology you wish to see(for eg. star)> next > enter number of perimeter nodes>next>next>next>next>finish.

Thanks a lot Ashika the link very useful to me to start working in omnet tool 

.

[athithi n]

Hai  Ashika , I was created the source file for simple module. And  by your guidance i will create the topology(Star). But in this two type of modules are created 1.node 2.hub.Can I create source file( node .cc and hub.cc) for these two modules?

 And also I refer the tic toc tutorial, in this  tutorial the source file uses the constructor and destructors in the Tictoc6 example .I don't understand why it is used?

[Ashika naik]

Yes you can create .cc file.

From c++ basics, a class constructor is a special member function of a class that is executed whenever we create new objects of that class.

and for setting initial values for certain member variables.So from this I think constructor have been used for initializing pointer " *event " in tictoc6 example.

And destructor we know it is executed whenever an object of it's class goes out of scope or whenever the delete expression is applied to a pointer to the object of that class. Also, its useful for releasing resources before coming out of the program. So in that example destructor may been included since delete expression "cancelAndDelete(event)" is applied for a pointer *event.

Sorry for late reply.

Thanks

[athithi n]

Thank you so much Ashika naik for your great reply.

[athithi n]

Hai Ashika Can i set random values to every nodes and Also can I save the values? Because  based on that value i want to select a cluster node ( which node has the greater value ).

Its my Host.ned file

*********************

simple Host

{

    parameters:

        

        double txRate @unit(bps);          // transmission rate

        

        double slotTime @unit(s);          // zero means no slots (pure Aloha)

        double x @unit(m);                 // the x coordinate of the host

        double y @unit(m);                 // the y coordinate of the host

               

        @display("i=device/palm2");

}

Its my Network.ned file

*************************

network Network

{

    parameters:

        int numHosts;  // number of hosts

         @display("bgb=694.768,684.72797;bgg=350,1,grey95");

       

    submodules:

        server: Server {

            @display("p=696.776,-58.232");

        }

        host[numHosts]: Host {

            @display("p=531.136,162.368");

        }

}

Its my  Host.cc file

**********************

#include "Host.h"

Define_Module(Host);

void Host::initialize()

{

   

    getDisplayString().setTagArg("p", 0, par("x").doubleValue());//nodes initially random position 

    getDisplayString().setTagArg("p", 1, par("y").doubleValue());//nodes initially random position

}

void Host::handleMessage(cMessage *msg)

{

}

Its my .ini file

****************

[General]

network =Network

**.x = uniform(0m, 600m)

**.y = uniform(0m, 600m)

Where and how can i create the generate the random numbers and how to assign that values into each nodes? plz help me.
