help, can somebody help me to trace that where is wrong with my tcl code ?
global ns
set ns [new Simulator]
# Note: Even though "Static" is normally reserved for static
#topologies, the satellite code will trigger a recalculation

does any know how to simulation burst error model ?

hello everybody,
i want to use error model in ns2
in queue/errmodel.h
there are two state error model,Complex Two State Markov Model,Multi

are they work independently?
what i need is multi state error model
Could anyone tell me how to use that?
Hi,
I'm running wireless 802.11 simulations in ns-allinone-2.29 and I'm having
some problems tracing the errors. When I insert an error model in my tcl
script I cannot see any dropped packet in the resulting trace file. I
inserted an uniform error model with rate 0.2 (20% of the packets should

Hi all,
I'm currently working on a project about OLSR with multiple channels
wireless mesh network. I've seen some online tutorials on how to integrate
multi-channel in ns2.26 and ns2.29 from W.H.Q and Wang Bo respectively,
but still has no luck to make it works. I would like to know if there is
hi,
there is someone who can help me : i want to display the priority and the
size of contention window of every flow on the ad hoc network simulation by
modifiying the mac-802_11.cc
thanks !

If you plug the values in the formula
PER=1-(1-0.001)^8000 = 0.9996658
The above result implies that 99.96% of you packets will have errors and
if there are no additional error correction mechanisms, they will be
dropped/lost. A BER of 10^-3 is too high and is not practical. For
example, in most

for example :

As far as I know, the relationship between BER and PER , assuming that
bit errors are independent and uniformly distributed is,
PER=1-(1-BER)^N where N is the number of bits.
However, the above formula is only approximate because in real life
scenarios, the bit errors are not completely indepe

Hi,
as far as I understand, seed is the base value for the random number generator,
i.e. when you chose a seed (other than 0) when you run the generation twice
with the same parameters, the generation results will be the same on both runs.
rate is the sending rate of the generated connections,

i m trying to implement a new routing protocol on ns (ad hoc network) and i

Thanks a lot.
