👁‍🗨 How to invoke MATLAB graphs for EdgeCloudSim

There isn’t a lot of documentation about EdgeCloudSim, more so of how to actually generate these beautiful MATLAB graphs. In this post I’ll go through a step by step of how to do so.

(A)  100 Mbps	(B)  300 Mbps	(C)  500 Mbps

1. Run the simulation

Please refer to my previous post’s Installation section to see how to run the simulation.

• The output will be saved at sample_app1/output/
• The simulator outputs the results of n iterations, where the ‘ite.log’ files are provided as a human-readable log of the simulation results, and files in folder ite’n’ to be fed to MATLAB for plot generation

2. Edit getConfiguration.m file to define your output log folder path

The file resides on sample_app1/matlab/getConfiguration.m. Make sure you define the path with ite output logs like below.

Filepath

ret_val = '/Users/chaerim/EdgeCloudSim-master/scripts/sample_app1/output/02-04-2020_21-16/default_config';

Change this line depending on your configuration.

2-2. For Mac/Linux user: edit ‘plotGenericResults.m’ ‘s filepath line from ‘' to ‘/’(line 24)

Below code will parse the path for individual files and feed it to the functions. You might need to fiddle with these two files a little - the problematic part that took me a while to figure out.🤣

filePath = strcat(folderPath,'/ite',int2str(s),'/SIMRESULT_',char(scenarioType(i)),'_NEXT_FIT_',int2str(mobileDeviceNumber),'DEVICES_',appType,'_GENERIC.log');

3. Invoke plot__.m files as you need (NOT the plotGenericResults file)

4. Voila! Repeat the above for different simulation output folders.

Hope this helped. Let me know if you need any further clarification.
