Hello ns users! I'm currently trying to integrate a new MAC protocol with ns-2.34. The code was highly based on the existing implementation of Smac in ns. I have edited some files (to add the new packet type etc.) and finished recompiling ns successfully. Here are the files that I edited: 1. Placed X.cc and X.h in ns-2.34/mac/ 2. packet.h and ns-packet.tcl 3. ns-default.tcl 4. cmu-trace.cc 5. ns-lib.tcl However, when I tried running wireless simulations,I wasn't able to send packets successfully because the packet type was invalid. It seems that I wasn't able to completely define the new packet type. Can anyone help me? Thanks in advance! :)
