There is a patch by Marco Fiore that implements the AARF algorithm, you can download it from http://www.telematica.polito.it/fiore/ AARF (Adaptive Auto Rate Fallback) is an algorithm that decides which bit rate should be used depending on the characteristics of the wireless channel. It makes its d

ns does not currently model such fluctuations (i.e. ARF,RBAR, or OAR). the data rate used is always the same. On 9/14/06, Piyush Agrawal <[EMAIL PROTECTED]> wrote: > > Hi all, > > I wish to implement a feature for 802.11, in which I need to know the > current physical data rate of the wireless m

[ns] Measuring physical data rate for wireless medium

2006-09-14 Thread Piyush Agrawal
Hi all, I wish to implement a feature for 802.11, in which I need to know the current physical data rate of the wireless medium form the C++ code. I know that in the real world scenario, the data rate fluctuates. Does ns model such fluctuations and can the changing rates be measured? Thanks, Piy
