Good afternoon all, I am doing a performance evaluation of the ETX and IBETX routing metrics for different routing protocols (AODV and DSDV). everything is working fine when i do simulations up to 50 nodes but when i try to go above 50 nodes in my tcl scripts i am getting the following error: anyone who knows what's going wrong?
