Sending multiple messages to same node simultaneously

[Mohamed El-Bahrawy]

Hey there,

I am new to Omnet++ and I am having a problem.

i created  10 simple modules ( 5 modules transmitting messages to the other 5) so that <module 1 to module 2 , module 3 to module 4 , etc.
 

But in the simulation , messages are sent one by one so that message from module 3 to module 4 should wait the one from module 1 to module 2 before been sent.

Can I have all the modules sending messages simultaneously ??
