Hi, I have a question about NS-2's 802.11 modeling (or lack there off) of SINR/SNR. I've been going through wireless-phy.cc and as far as I can tell,there's no SINR modeling at all. To receive a packet successfully, the receiving side checks if the received signal power strength is greater than both CSThreshold and RXThreshold. There's some mention of a capture threshold where if another packet is received at the same time, the first packet will be received successfully if its signal strength is CPThresh* the other signal. However, I don't see it being implemented any where. Am I reading this right? Is there no SNR or SINR modeling at all?
And are there any patches that implement a more accurate physical layer and are good for MANET simulations? Thank you. Chun Ming Lee
