Excellent, it's great that you're uploading content again, your videos are very interesting, I would suggest a video on how to orchestrate lambdas in AWS.
Thank you so much ><!
Thank you Dr.❤
A very wonderful introduction lecture. Thanks a lot. Dr.
why do I get Error: type ':containerFlowType' not found in my trip file
please help me
Thank you Dr.Joanne this is very helpful
thank you so much!!
maam you are great thankyou for upload please share more knowledge about this OMNet++.as a students it is help to start from your tutorials
I run following: C:\Users\me\Desktop\omnetpp> C:\Users\me\Desktop\veins-master\veins-master\sumo-launchd.py -vv -c 'C:\Program Files (x86)\Eclipse\Sumo\bin\sumo-gui.exe@ But When I go omnet and run simulation, example is running in omnet but I see shell: C:\Program Files (x86)\Eclipse\Sumo\bin\sumo.exe is poping out only sumo is not coming
Well Explained!
Can anyone please tell me, what is the version of INET used in the project described in this video. How can I get to download this particular version of INET-framework. Kindly, help me with this. Thank you.

Joanne. Thank you a thousand times and more
Thank you! I came to this because I suspect the parking lot and the routing used to pick up my grandchildren from their school in the afternoon, is suboptimal. I'm pretty sure I'll be able to create the model I need to determine my hypothesis one way or the other.
Thank you!
I enjoyed your style of explanation - any chance you’ll do a video on rule of 5 and move semantics as well?
like it thanks, for the explaination
Hello, I have a question where is the link for discord channel?
Thank you Dr. Skiles. You have really helped me. Please I would like to ask you to do more video tutorials because goo material on OMNeT++ is so rare. Kudos
Hello, how can I solve:"Script execution is unabled for the used system" VSCode terminal issue? Ty in advance!
One thing to note here, the compiler sees obj3 = obj1 differently than RuleOfThree obj3 = obj1. for obj3 = obj1, compiler sees it as mere assignment operation and it executes the default copy constructor, but if compiler sees RuleOfThree obj3 = obj1, it will execute the user-defined copy constructor.
This was a great video Dr. Skiles. You explained everything clearly and made it very easy to digest. I'm glad I cam across this.
need more videos in this tutorial, specifically comparing between routing protocols and show results
Thank you for the explanation as to the why as well, that's what I was looking for.
So easy an Indian could do it!
can u help me to build project in simulation for mobility devices verticle handover with ml prediction
I did the same steps on ubuntu 18. it even worked when I opened the dyna example but when I wanted to open the omnet with omnetpp command line it just wrote that is starting omnet and nothing happened. then I rebooted my ubuntu then tried the command line and now I see the ubuntu does not recognize the omnetpp command line. Does any body knows how to solve my issue???
Did aws recently change the IAM UI for edit policy to add permission part? Seems like I cannot find it
For anyone following the installation procedures for windows, make sure to install SUMO version 1.0.1, else u might encounter issues while running simulation. I installed SUMO version 1.19 and got the following message when i tried to run veins' example scenario simulation: A runtime error occurred: TraCl server reports unsupported TraCl API version: 21. We recommend using Sumo version 1.0.1 or 0.32.0 in module (veins::TraClScenarioManagerLaunchd) RSUExampleScenario.manager (id=6), at t=0s, event #1
this one of the better informative videos ive ever seen
Thank you so much for thoroughly explaining every concept! I've watched so many videos for my Data Structures & Algorithms class and I'm STOKED that I found your complete tutorials playlists!!!!
I'm getting an error, it says it can't load the configuration file in SUMO
Please, could someone help me better navigate node-TSN pre-definitions in INET ? I'd like to use the TsnDevice offered by INET in my network architecture. According to the NED file of the TsnDevice module, the hosted applications are of type 'lApp,' and only the NED file is found in the inet.applications.contract directory. Willing to add some operations to the handleMessage of packets in lApp, I generated an lApp.cc and lApp.h in the inet.applications.contract directory. However, during simulation, I observe that these new files are not being considered. Could you please assist me? Thanks in advance
thank you professor
Thank you, Dr. Joanne. I hope to complete more videos in this area I have a questions how can compare between routing protocols in VANET using OMNET++ and SUMO ?
great video. thank you
Great tutorial! Thanks for putting it out!
Great explanation, came in not knowing and left knowing
Thanks for the tutorial. Installation worked, but when I tried to run the aloha samples, QtEnv was opened with empty window, which is shown in the taskbar but cannot be maximized, and in the console, I see the error: CreateFontFaceFromHDC() failed ...... I tried to find the solution to this problem but so far no luck. I also tried to run an example from within the Omnet++ IDE, but it got stuck in the initialization.
Yeah woman in tech🎉😭
Thank you. Very helpful.
Condition Expressions seem pointless on putItem because it will fail anyways with a duplicated PK so why even bother including it in the Put? or am I missing something? :)
Please provide you email address I need to communicate for my PhD work
Bless your heart for making these tutorials but it would be helpful to those of us without the best of vision if you would kick the font size up a notch if you ever create more instructionals. Thanks again
Pls explain for me how to connect sumo with my pc's OneDrive ?
A nice tutorial but I have found it's a tiny bit easier to to visualize when replacing the identifiers i and j in the for loops with row and col. Insignificant in function I admit but a slight aid in seeing how the two loops work together with the array dimensions. Love your work.
Salam, can I contact with you via email?
Mam Can u pls let us know from where to study omnet++, apart from it's manual
hey guys im really struggling with my research project can anyone help me regarding importing the project please. Im facing various issue. please revert back if anyone has knowledge regarding OMNET
Vtl?? 😮😮😢😢😢
