[ns] Random motion in a limited zone

[El hadi Cherkaoui]

Dear Ns user,

I want to know if there is a function in tcl to define a random motion for a 
noe like : 

$node_($1) random-motion 1

but in a certain zone ( i want to define a limit for this zone )

Regards.





  

[ns] random motion

[sinduja R]

hi guye, please tell how to add random motion features to mobile node..

i gave $node random-motion 1

but the mobile doesn't seem to move at all..

[ns] random-motion 1 and initial position

[sara MA]

Hello everybody:

Can you please tell me if it's possible to have random movement of nodes 
(random-motion 1), but also having cutomized initial postion of nodes. I 
want to set the initial position of nodes by myself and then let them move 
randomly.

Thanks in advance for any suggestion,
Sara

Re: [ns] Random motion for ad-hoc network

My beleive is whenever I run the ns command for my tcl file, the nam file 
for that tcl file is overwritten, am I wrong?

  run the nam file,  the initial positions of nodes is the same as last 
time,
  and they even move in the same way they moved as last time.
 
  Do you know what maybe the problem?

Hi sara,

Running NAM against the same namfile will always produce the same node
mobility.

I suggest that you look at Marc Greis' tutorial Chapter XI.

That's right.

However the nam file will always be the same as you are supplying node 
mobility with the same mobility file (.scen).

Hello,
What does setting random-motion to 1 do to a wireless node?
I see no movement in nam when I run a simulation.
Thanks,
