Sir, I came to know about you from your university site. I am M. Sc student from Nepal. I am doing my thesis in Wireless QoS. I am trying to implement 802.11e and compare it with previous legacy 802.11. While implementing it using TCL scripts in NS2, I couldn't make a collision environment. At any instance only one node will be active and I cannot make pseudo parallelism for collision to occur so that I can analyze the packet loss, delay etc.
I really need some help to go further, It would be great help if you can suggest me some way out. If you have any sample code or any reference link where I can find the information about it. Thank you for your time. I would be looking forward to seeing you soon. Sincerely, Rajiv Nakarmi
