[ns] simulation time of DSDV

[leily A.Bakhtiar]

Hi dear friends

I wrote a scenario in wsn with 30 mobile nodes and 20 static nodes. I run
this tcl file with AODV , AOMDV and DSR, it was true. But when I changed
the routing protocol to DSDV it doesn't show its nam , I try it for 4 hours
but it didn't work without showing any error.

Is the run time of DSDV very long?


Best regards.

[ns] simulation time

[Giuseppe]

Hello List,

I have a problem when I run one simulation of approximately 60 second ones. 
after approximately 25 second ones, the system jams. on what it can depend? 
It probably can be legacy to RAM of small dimensions?

Help me and thank you

[ns] simulation time in WiMax

[SERIEN SERIEN]

Hi all
  I have a problem when running WiMax tcl code in ns2. The simulation 
time is more than 10 seconds and if there is traffic starts after 10s it 
does not appear in the trace file.
  If any body has an answer please I need a reply as soon as possible.
  Thank you

[ns] Simulation Time

[ahmed nagy]

 Dear All
I am developing a routing protocol and i would like to know how long should
i simulate it in order to get dependable results. I have 50 nodes in my
network in an area of 1000*1000 with a transmission range 250 m. Should the
experiment be repeated and the results averaged. if yes  How many times
should the experiment be repeated. Any idea would be appreciated. I
appreciate your response and help
Thank you

[ns] simulation time / actual time ratio

[sagar tamhane]

Hello,

When I run the "ns abc.tcl" command, the simulation time is not the same as the 
actual time. How do I make this ratio 1:1?

I am not interested in the nam trace file and I donot want to use emulation and 
hence cant use "RealTime".


Regards,
Sagar

Happened with my simulations too. I ran the simulations for 100 seconds.
I left out the 5 seconds at both ends of the simulation and results are
consistent.

Arun

If you like to know the values in a steady state you sould run the
simulation 
for at least several minutes. Especially in the first few seconds you
can 
experience several strange effects. Something I often see is a storm of
ARP 
packets at the beginning of a simulation because all stations start to 
communicate at about the same time. So, it is sometimes better to
discard the 
results from the first seconds.

[ns] simulation time in ns-2

[Michael Sidiropoulos]

  Hello everyone!!
I have a question regarding simulation time in ns-2
I am using ns-2.27 version and i have noticed that the calculated 
throughput in my wireless scenario changes as the simulation time 
increases.What  simulation time should i set to my tcl script in order to 
get
accurate throughput results?

Any point or hint is extremely welcomed
Thanks for your attention!!!

Michael
