Nodes with different energies

JAFAR-KEFAH · 06-09-2021, 06:23 AM

I am working on my project. It is about detection of selfish nodes depending on the energy of the node. Here I have 20 nodes of the same energy, then I added 5 more but with different energies. The program shows that there is an error (as listed at the end of the code).
My code

This is now your third thread related to NS...and you never bothered to follow up in your other two:
https://www.linuxquestions.org/quest...le-4175695890/
https://www.linuxquestions.org/quest...wk-4175695821/

You have been asked before to use CODE tags when posting, and have ignored that too. You have been asked for details about your system previously, and posted that you were using NS2.35 on Ubuntu 18.04, and were informed that the scenario in question wouldn't work...and don't tell us what you're using NOW, if it's different. You say this is 'your' code...if you wrote it, it should be easy for you to debug. If you didn't, you aren't telling us what you've done/changed in this code that you downloaded. We can't guess, and if you're not going to follow up on any of your threads, why post?
