Dear Gregory Butron, 1. To answer your question directly, yes, it is possible. But that approach does not make sense, as you would compromise the integrity of a simulator. For e.g when a frame is currently being received by a receiver node and another new frame arrives overlapping in time, only the strongest frame will be received by the receiving node. The weaker frame will be discarded due to collision by IEEE 802.11 MAC i.e one of the typical frame loss scenario. Modifying the simulator to accept both frames does not make sense from Physical or MAC layer point of view.
2. What I would suggest is to mark frames lost due to propagation model separately than any other frame loss scenarios. Later you can do you own accounting to find the loss incurred due to propagation model. Try to Google on how to do this. 3. The method in #2 above is practical and accommodate your requirement, as, when a MAC send a frame from a transmitting node, it goes through a wireless channel with a certain propagation model, when received by a receiving node, test will be done to see if there is any error caused by the propagation model. The below function line would interest you WirelessPhy::sendUp in Wireless-phy.cc Good Luck. rgds Saravanan K On Thu, Sep 20, 2012 at 1:35 PM, Gregory Butron <gregorybut...@oru.edu>wrote: > > I am working on a wireless network simulation where I want to look solely > at packet loss caused by fading (using the Nakagami propagation model).
