Simulation in aqua-sim
 

Dear all,

I'm developing a routing protocol for underwater sensor networks in Aqua-sim. I am trying to run the the tcl file but I'm getting this error:

can anyone help me, please?

Welcome to LQ.

Please attach your tcl file as file-name.tcl.txt .

memory corruption when running a routing protocol in ns2
 

Thank you. I have solved the problem, but now I got a memory corruption problem.

I set some varaibles to some values but when i tried to use them, their values are changed to some strange values.

Hopefully, you can assist me to solve this problem.

# 3 .

'mggr.tcl' line 35 :
set opt(rp) MGGR ;# Routing protocol

? Is MGGR a new routing protocol, that you have created ?

-

Yes, that is my routing protocl.

# 5 .

Please describe the "routing protocol MGGR".

And attach the code / upload the code to 'Google Docs,
if you want your mggr.tcl file tested.

-

I'm sorry, I can not disclose the code because it will be my thesis.

I appreciate your intention to help me.

Thank you..

The origin of the coordinates in aqua-sim
 

One more question, please:

Where does aqua-sim assumes the origin of xyz-coordinates, is it at the sea surface or at the bottom?

Thank you in advance

# 8 .

Probably like shown in the other application from `obinet´ : Aqua-3D →
http://obinet.engr.uconn.edu/wiki/index.php/Aqua-3D
→ http://ubinet.engr.uconn.edu/aqua_pa...-1.0.0-src.tgz
→ Aqua3d-1.0.0-src.tgz

i seems from aqua 3D that the origin is at the middle of the monitored volume (middle of the sea).

However, in vbf_example_6.tcl written by the develpers of aqua-sim, nodes are given positive values and within the range of the length, width and hight of the monitored volume.
