Welcome to LQ.

Testing ...

Code:

$ ns235-64-orig bharaths-vanet.tcl 
num_nodes is set 100
.
INITIALIZE THE LIST xListHead
couldn't read file "mobility.tcl": no such file or directory

I.e. the movement file is missing.

It's a huge area.
But anyway, if at all possible with "a million meters", x and y must be some larger than the max "setdest value".
Suggest :
set opt(x) 900000
set opt(y) 1510000

EDIT : Confirm → works OK with a random movement file, max x: 801806.63 , max y: 1506654.91

Hi,

thank you so much for replying.. it works..

as you said for the setdest values greater than x and y are throwing error..

i have a doubt. there are 100 nodes and multiple setdest values. should x and y values be greater than all the setdest values in the file?

file size is more than 2mb i cannot attach the file. i will copy paste the data here.. could you please suggest how to get proper values for x and y in SUMO..

Re #3 : Please do not quote entire posts. A "one word reference" will do.

And : Please edit post #3 to use CODE TAGS around the "setdest snippet"
http://www.linuxquestions.org/questi....php?do=bbcode
I.e. write [code]code text[/code]

Yes. See post #2. Why do you think you can go outside the communication area ?

( Some types of ns2 simulation : X, Y settings are ignored.)
