Dear Sir, I am a senior at Bilkent University Ankara/Turkey. I will have a senior project about mobile IP. My question is whether I can use ns in my project for simulations. I would be glad if you inform me about the subject. Thank you for your help in advance. Yours faithfully, OZAN SOLMAZ BILKENT UNIVERSITY DEPARTMENT of ELECTRICAL and ELECTRONICS ENGINEERING.
