Hi there
I also tried that a few months ago, but it does not seem to do what it says
i personally think it is useless, unless someone has other opinion

Hi there
from my simulations and keeping it simple
The default range for the packet delivery is 250m and that of Carrier
sense Threshold is 550m, so from Node A --->B if the distance is less than
or equal to 250 , then , the packet will be recieved successfully. If the
distace is greater than 2
Hi there
I think there is no other cleaner or easiar way to do that unless you
modify the code.
One thing you have to be aware of is that by modifying the transmission
range, you are only changing the receiver threshold, A distance from
which a receiver can receive.
Again there are three diffe
Hi there
please have a look at the info at this site
ns2 for the impatient
http://icapeople.epfl.ch/iaad/teaching/ns/ns.html
It has examples on how how to calculate and display the throuput of 802.11
network and also how to set the different data rates
I hope this helps

Hi Jackie
please go to the link below and download the document and the tools files.
http://icapeople.epfl.ch/aad/teaching/ns/ns.html
The document shows you how to setup a scenario to measure the throughput
step by step for 802.11 for any other protocol you require.
The tools folder contains a
Hi there
I think what you need to do is to read the files, mac-802_11.cc and .h
file in the mac folder. This will give you all the information you require
however from the the simulations I have done, I got the following values
Data packet can be any length you like, however a 72 byte overhead
Yes its simple
just add the below line
Mac/802_11 set RTSThreshold_3000

Hi Paolo
First of all I think the the free space model and two ray ground model
are dependent on antenna height and there is a crossover distance, after
which the model used is two ray ground. When you say you use free space
model, you must have the antennas to be very high, to acheive a free sp
very simple
have a look at the file tcl/ex/wireless-mitf.tcl and declare your channel
as shown in that file

Hi there
What you really need to do is to see that if you have two different pair
of nodes. One pair with the same range e.g. 50m and another pair with the
range 100m. You set both the pairs apart o they cannot interefere with
each others transmission. You will see, that the transmission range of
