This article is for my fellows class mate.<\/p>\n
1. I think you all have no problem with OMNET++ installation – just running the installer if you are using Windows, for Mac OS X please refer my previous article.<\/p>\n
2. Then download the Inet Framework, if you are using Mac OS X please refer previous post. If you are using windows please make sure you had installed winpcap driver first. Do download it at http:\/\/www.winpcap.org and download the installer.<\/p>\n
3. Extract the Inet Framework on your omnet++ workspace.<\/p>\n
4. Go to the Inet parent directory, then please READ the INSTALL file for further understanding.<\/p>\n
5. Now import or compile your Inet with omnet++. For Mac OS X please refer my previous post. For windows you can do it using command prompt or using the IDE.<\/p>\n
6. For IDE just follow the INSTALL file instruction. As follows<\/p>\n
i. Open the OMNeT++ IDE and choose the workspace where you have extracted the inet directory. The extracted directory must be a subdirectory of the workspace dir.<\/p>\n
ii. Import the project using: File | Import | General | Existing projects into Workspace.Then select the workspace dir as the root directory, and be sure NOT to check the “Copy projects into workspace” box. Click Finish.<\/p>\n
6. The inet folder should appear on you Project Explorer<\/p>\n
7. Expand the explorer tree : Inet – examples – inet – ber<\/p>\n
8. Click on omnet.ini – in the form wizard click on Event Log – Thick Enable eventlog recording – this is for record all of your results into results folder. The graph will automatic generated with the recorded data.<\/p>\n
9. Click the source of omnet.ini and edit the BER value as follow:<\/p>\n
The default value is zero “0”<\/p>\n
# BER (bit error rate)<\/p>\n
**.n = ${ber=0, 1e-7, 2e-7 …and so on…<\/p>\n
so change the ber=0 to what do you want, example 0.1<\/p>\n
**.n = ${ber=0.1 …. then save as the .ini file with others name example omnet-kosong-point-satu.ini<\/p>\n
so now we know that this config file is for BER value 0.1<\/p>\n
10. Next is create others config file with the other value 0.01 , 0.001 and 0.0001.<\/p>\n
11. To run the simulation, select respective config file and click the green PLAY button. Wait for a while and then.. tadaa… now you should have the animation and click RUN (pastu ada gerak2) \ud83d\ude42<\/p>\n
12. After finish the simulation, close down the simulation window and go to the results folder and click on your result log file and you will get the graph \ud83d\ude42<\/p>\n
13. What to do now ? Hope you guys can deeply study the graph all about and then share what you get in our next class ..<\/p>\n
