First, thanks for reply, I have checked the indicated paper but I have not
found what I want, in the paper the authors determine the best next physical
mode to be used for the next transmission based on SNR, frame length, and retry
count. However, I want the BER vs. SNR curve values for
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
Hi,
Are you running the ns command from the appropriate directory? Is your
xwindows running?

Hi
I have installed Cygwin and configured network simulator2 in it but
when ever I try to run it, it gives that bash ns command not found.
Hi Qasim,
Thanks for the reply and giving suggestions on the tesing scenarios.
I made another test as you suggested, however, the result still looked
positive. The following is a brief description of the settings.
Two pair of nodes are create. The first pair includes n0 and n01, and they
have
I am sorry, the script messed up. Send it again.
script:
# First pair: n0 and n1, placed at the topology bottom, receiving range 50m,
carrier sensing range 100m
# Second pair: n2 and n3, placed at the topology top, receiving range 100m,
carrier sensing range 200m

Hi there
It seems you have been working harder settuping up the scenario
Yes I can see a slight problem in your script
Phy/WirelessPhy set CPThresh_ 10.0
Phy/WirelessPhy set CSThresh_ 2.78831e-9;#100m
Phy/WirelessPhy set RXThresh_ 1.11532e-8;#50m
Phy/WirelessPhy set bandwidth_ 1Mb
The first pair did not communicate. Only n3 received packet means there was
no data connection established between n0 and n1.
As to the transmission range, it depends not only on transmission power, but
also the receving threshold, and propogation model. ns2 uses TwoRayGround as
the default
Hi,
I am working on modifying the bandwidth available in wireless networks. Could
some tell me where (the name of the file) the bandwidth computation is done
after the signal strength is computed. In the case of two ray ground the method
TwoRay() computes the power, The method Pr() actually
Hi
I'm looking for a way to create a scenario where not all of my wireless
nodes have the same link capacity, that is I would like to model a situation
where two nodes can send/receive data at a rather high speed, while
intermediate nodes (in a multihop scenario) are slower.
I can't seem to
