Dear ns2 users, I'm using ns2 to perform wired-cum-wireless simulations. As regards the wireless channel+MAC model, I do not understand the real differences between the traditional IEEE 802.11 MAC model and the Ext one. I've checked the ns2 documentation to discover that the Ext one is just a refactoring of the previous model with additional fading techniques. Is this correct? If not, can you briefly explain me the principal differences between these two models? If any, which model is more accurate?
In addition, I need the simulation parameters for the IEEE 802.11g model. I've found some solutions (http://hpds.ee.ncku.edu.tw/~smallko/ns2/11b.htm, http://blog.chinaunix.net/u/21684/showart_1076725.html), but I'm not sure that they consider all the necessary parameters. Can you confirm me that the parameters considered in the previous links are enough to simulate a correct IEEE 802.11 channel? Thank you for your attention.
