NS2 doesn't simulate SNR, it is based in thresholds. If the signal at the receiver is weaker than CSThresh_ the packet will be discarded at the physical layer, if the signal is weaker than RxThresh_ the packet will be marked as corrupted (error flag = 1) by the physical layer and send to the mac layer.
For SNR support in 802.11 check http://www.tlc-networks.polito.it/fiore/ Guillermo Hi, How can I obtain the SNR value at a node during the simulation from the C++ code? I need this to simulate a link adaptation algorithm.
