ERROR WHEN RUNING OVERSIM ON OMNeT++ 4.6 USING IDE

[Sara kh]

Hello OMneT users,

I need your help, firstly oversim was runing perfectly (using IDE) with no problems, and then when i try to run it and choose one of the configuration models for example : Chord (iterative, SimpleUnderlayNetwork) or any other model, i got this error:

Error in module (SimpleUnderlayConfigurator)

SimpleUnderlayNetwork.underlayConfigurator (id=2) during network initialization : coordinate source file not found.

I tried for a week to resolve it with no suceed, Would any one help me PLZ,

Regards.

Configuration problem, oversim uses an xml file with the position of the nodes, the program can’t find the file

 

In the ini the parameter is

**.nodeCoordinateSource

 

The oversim examples uses the file nodes_2d_15000.xml

Thank you Professor for your answer,

Yes it is specified in default.ini file with this line:

SimpleUnderlayNetwork.underlayConfigurator.nodeCoordinateSource = "nodes_2d_15000.xml"

I verify that "nodes_2d_15000.xml" file already exists in oversim/simulations directory; in spite of that i got this error that "courdinate source not found", what should i change to resolve it!

[Alfonso Ariza Quintana]

You can check if the name is correctly read in the ide, in the ide you can see the values of the parameters.

I juste checked, and it s the same name "nodes_2d_15000.xml" in default.in and in simulations directory.

What made me confused is that it worked firstly with no problems,

although I've made no change.

[Alfonso Ariza Quintana]

I cannot imagine what the source of the problem is,

Hi,

When trying to resolve this problem i changed the Working Directory in run configurations from "oversim" to oversim/simulations", but i got this error :

Running simulation...

<!> Error in module (SimpleUnderlayConfigurator) SimpleUnderlayNetwork.underlayConfigurator (id=2) at event #2, t=0: While evaluating parameter `ber': Parameter is not yet accessible.

Would you help me PLZ.

It works finally, thank you so much!

Hi,

My question is about the mobility module presented in https://github.com/aarizaq/Oversim-20121206 , is that for applying an overlay protocol like CHORD over a mobile network??

Another question is how to get it work? I tried to change “InetOverlayHost” in default.ini by “InetOverlayHostAdHoc”, exactly in this line :

InetUnderlayNetwork.underlayConfigurator.terminalTypes = "oversim.underlay.inetunderlay.InetOverlayHostAdHoc"

 

But I got tis error:

<!> Error in module (Radio) InetUnderlayNetwork.overlayTerminal[0].wlan[0].radio (id=107) at event #29, t=0.098459035: Could not find ChannelControl module with name 'channelControl' in the toplevel network..

 

My work is to apply CHORD over a mobile network, and I am still new with Omnet and Oversim, PLZ help me.

 

Regards.

[Alfonso Ariza Quintana]

The radio interfaces need a ChannelControl module, without it the code can’t model the radio transmissions. See the wireless examples

This happens mainly due to "run configurations" . Make sure working directory is /OverSim/simulations and not /OverSim/ . Even though nodes_2d_15000.xml file exists , it does not look into it without correct configurautions.

Thank you,
Sumanth.
