Re: [ns] 802.11b rates in 802_11Ext model

2010-04-21 Thread Elena Buchatskaya


I saw the source code of 802.11Ext model and found put that there is only one
parameter connected with rate - BasicModulationScheme_ . I didn't find how
to set coding rate in this model. It is very important to conduct my
experiment with different rates.  Can anyone help me to solve this problem?
Or is it possible to simulate 802.11b network ONLY with 1Mbps rate?

 Hi 
 
 I try to run simple test with two nodes using 802.11Ext. I set parameters
 according to 802.11b specification. When I run at 1Mbps everything is ok.
 But I don't know how to set another rates: 2Mbps, 5.5Mbps and 11Mbps. How
 should I specify following parameters 
 
 Mac/802_11Ext  basicRate_ 
 Mac/802_11Ext  dataRate_ 
 
 Phy/WirelessPhyExt  BasicModulationScheme_ 
 Phy/WirelessPhy  bandwidth_ 
 
 to obtain 802.11b network with for example 5.5Mbps rate? 
 Thanks in advance.

I'm trying for a given wireless link to calculate the SINR. Has anyone
already done it before ? do I need the  dei80211mr mac extension or could it
be done using the default mac 802.11 implementation bundeled with NS 2.34 ?

[ns] Ns traces and custom headers

2010-04-21 Thread Giovanni Di Stasi

Hi everyone,

we are doing some experiments with packet aggregation in wireless adhoc
networks. For aggregating packets, we use a custom header between layer
2 and the layer 3 (so we aggregate different IP packets on a single
layer 2.5 packet).  We have a doubt regarding the traces.  We want to
calculate the rate of the communication between a source and a
destination of the network. To do that, we  consider all the send and
receive events at the AGT level related to IP packets. Then, we do not
consider aggregated packets  (the ones marked with our custom header),
as we suppose that the IP packets contained in them have already shown
up as single IP packets. Is that correct or should we consider also
those packets?

Thanks,
Giovanni
