can't read "a_(5)": no such element in array
while executing
"$a_($i) set data_rate_ [expr 1.0/$opt(interval)]"
("for" body line 2)
invoked from within
"for { set i 1 } { $i<$opt(nn) } {incr i } {
$a_($i) set data_rate_ [expr 1.0/$opt(interval)]
$ns_ at $start_time "$a_($i) cbr-start"
set start_time..."
(file "/home/squ/Aqua-Sim-1.0/ns-2.30/underwatersensor/uw_tcl/vbf_example_5.tcl" line 304)

Please help.

P.S. : A contemporary Ubuntu OS may not be very usable for aquasim.
? Are all the default (12) examples running OK ?

Example HOWTO format / upload a file.txt with usable code :
https://drive.google.com/file/d/0B7S...ew?usp=sharing

Your files are not very readable with "ns-aqua".
Looks like they are made with a Windows©© tool. Not "unix files".
And the 'dos2unix' command cannot fix it. I had to delete line 1 in the vbf...tcl, and retype the line.

Code:

$ ns-aqua vbf_example_6-Alkindi.tcl
can't read "node_(0)": no such variable
    while executing
"$node_(0) set X_ 122.49146098302171"
.

Please upload files written in e.g. the gedit editor. Preferable as name.txt .
And : You will have to respond to our questions : Repeat : Which Ubuntu ?
These commands will show : 1) uname -m 2) cat /etc/issue

Sorry !! the files generated by bonnmotion tool and then converted to ns file which have the extention : .ns_movement and .ns_params

tcl file :

The error I get is ...

Code:

$ ns-aqua-64 vbf_example_tcl.txt 
the file name is vbf_example_6.data
the sending interval is 10.0
num_nodes is set 100
Width=100
INITIALIZE THE LIST xListHead
Node 1 is sending first!!
starting Simulation...
GOD: the old file name istest.data
GOD: the new file name isvbf_example_6.data
ns: _o15 setdest 122.49146098302172 58.85417455781869 13.195859329293715 0.5220217175254592:
.
.
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."

I have no solution. And there is none of the default examples with a similar setup :
No lines with "setdest .. ..", or the use of external files.
And I don't remember any succes stories creating examples.tcl for aquasim.
See http://www.linuxquestions.org/questions/tags/aquasim/

Complex setups :
Please use 'Desert Underwater' http://nautilus.dei.unipd.it/desert-underwater
There is a 3.6GB VBox image you can import to VirtualBox :
http://telecom.dei.unipd.it/ns/deser...SERT_2.1.0.ova
It's LinuxMint, with /home/desert/DESERT_Underwater/\
{DESERT-2.1.0 : ns-2.34 + ns-miracle + uw-stuff.}

.... Samples.tcl :
/home/desert/DESERT_Underwater/DESERT_buildCopy_PC/DESERT-2.1.0-src/samples/{ desert_samples/, desert_with_woss_samples/}
-------

There is also aqua-sim for ns3 https://github.com/rmartin5/aqua-sim-ng
.. and https://groups.google.com/forum/?fro...rum/ns-3-users
Current protcol support includes:
[MAC layer]: BroadcastMAC, Underwater ALOHA, CopeMAC, Underwater FAMA, Underwater Slotted FAMA, GOAL, UWAN, RMac, Tmac, [Routing Layer]: DBR, Static, Dynamic, Flooding, VBF, and VBVA. Furthermore, Aqua-Sim NG core continues to support basic underwater functions such as half-duplex, long propagation delays, and acoustic signal attenuation.

The same error i got while running the tcl file ! One more question please. Any other method i could use them to generate mobilty models and use it with these tcl files in ns 2 ?

knudfl · 06-18-2016, 02:27 PM

Re #7, mobility.

NS-2 "node movements"

Most of the wireless scenarios created in 2D , i think the problem because i am trying to connect the 3D mobility models with the ns2 tcl examples ! i will try to use ns3 and check out the result .

Thanks again for ur help
