I am new to omnet++ and started using it a couple of days ago. I followed the tic toc example and now, I need to learn how to simulate wireless networks I need to implement a very simple example similar to tic toc scenario but with a wireless network and two mobile nodes
should I use INet/Mixim for modeling wireless and/or mobility? or there is another simpler way?
Yes you need to use INET for including mobility in your modules. There are several examples in INET which would help you in your project.
