Hello, I'm doing research on bit rate control algorithm for 802.11b and 802.11g links. Where can I check what algorithms ns2 uses? Best Regards, Guillermo

[ns] 802.11 dynamic bit rate change

2006-07-11 Thread guille
Hi, In real 802.11b and 802.11g wireless cards the bit rate changes dynamically depending on the channel conditions. If the card is working at 54Mbps and is receiving no ACK's from the receiver it will automatically switch to a lower bit rate. Modulations used by lower bit rates are stronger aga

[ns] documentation of error models

Two years ago I wrote my thesis on network simulation. As part of it I documented and tested the error models implemented in ns-2.29. Even if the notes are for and old version I think they could be useful for some people. Should I send the pdf file directly to the ns-users list? Regards, Guille
