Hi,
ns-2 physical layer modeling is notoriously weak. A patch solving some of the issues you mentioned is avaialble at http://www.reti.polito. it/fiore bye, Marco >----Messaggio originale---- >Da: [EMAIL PROTECTED] cmu.edu >Data: 8-mar-2007 3.21 AM >A: <[email protected]> >Ogg: [ns] SINR and NS-2 802.11 simulations > > >Hi, > >I have a question about NS- 2's 802.11 modeling (or lack there off) of >SINR/SNR.
