Csma/Cd

[guven]

Hi NS users,

I am trying to implement a CSMA/CD based lan in ns2 but while doing this i have realized that newer versions of ns2 does not support Csma/Cd MAC protocol and it offers to use 802_3 instead. However my aim in this project is to compare these two so i have implement both of them. during my research through the internet i saw that many people tell about changing some source files of ns2 to activate Csma/Cd but although i have tried i could not manage to solve this rpblem yet. Therefore i would really be very please if you explain how to implement Csma/Cd in newer versions of ns2. By the way i am using Csma/Cd during creating a new lan with "make-lan" command.

Thanks,
guven
