[ns] Rate Adaptation for the Multirate 802_11 using ARF Algorithm

[Firooz B. Saghezchi]

Dear all,

I am trying to implement the link adaptation of the 802.11g using the ARF (or 
the RBAR) algorithm. I added the following piece of code to the adhoc_tcp.tcl 
(the sample file in the dei80211mr-1.1.4), but doesn't change the rate 
correctly. Can anyone provide me some hints in this regard? 

    set ra($i) [new RateAdapter/ARF] 
    $ra($i) attach2mac $mac($i) 
    $ra($i) use80211g 
    $ra($i) setmodeatindex 0 

Thank you!
Firooz
