I want to model wireless channels according to rayleigh fading channel. But
I have not find any such support in NS-2. Could any one tell me how can i
use rayleigh fading model in ns2.
when i run a simulation i got the following messeges...
BEB limit exceeded: dropping packets
ns: scheduler going back in time from 7.0005683 to 0.000
Is it necessary to change the BEB limit?
How the scheduler can be prevented from going back?
thanks in advance.
Is there any way to dynamically change the bandwidth of a wireless link. I
mean, during first 10 sec of the simulation BW is 1 Mb, for next 10 seconds
BW is 2 Mb and so on. This is required when a user moves very fast.
Thanks in advance.

Hi everybody
I am running a wired-cum-wireless simulation. I am using rayleigh fading
model. I observed that most of the TCP ACK packets are dropped. Is there any
way to prevent these drops?
Thanks in advance.

In a wireless simulation, wireless links are modelled using rayleigh fading
model (fdT=.01). Do I need to insert an error module (e.g. drop packets at
.1% rate) in the wireless link? How can I control the error process? I want
to drop packets at 10%, 1% and .1% rate.

Dear all
Can you tell me how can i prevent ACK packet drops in my simulation. If TCP
packets are dropped then i do not have any problem. I have taken special
care for that. But as the ACK packets are dropped I am not getting the
desired result. Please answer ASAP.
