Integration of Matlab with OMNeT++

[baraldi]

Hi everyone,
Is it possible to integrate the matlab capabilities with omnet during
the simulation time? I know this is not probably an omnet feature and
objective but it would be really interesting if the matlab
mathematical capabilities could be integrated in a simulation
environment as omnet. My idea would be that of developing a mobile
network where test images are processed by matlab(encrypted
watermarked ecc) and sent through a noise network and processed again
by other nodes. Thx everyone for your attention

I have gone down this road before and it is possible; although it
ended up not being a proper solution to my specific research problem.

The Matlab engine is callable from C/C++ applications and there should
be a good amount of documentation regarding doing just that. My only
cautionary note is that you will want to make sure that only a single
instance of the Matlab engine is invoked by your simulation or license
and performance issues can arise.

http://www.mathworks.com/help/techdoc/matlab_external/f29148.html

Depending on how you are creating your simulation you may want to read
up on opp_makemake which gives details about including 3rd party
libraries and headers in OMNeT++ simulations.

http://www.omnetpp.org/doc/omnetpp41/manual/usman.html#sec262

An alternative to invoking the Matlab engine within OMNeT++ would be
to create the test images as input data for the simulation to consume
and then save them as output for post-processing. I don't know if this
fits your particular needs, but it avoids having to couple analysis
with your model.

Sorry for late answer and thanks for your help, I manage to integrate
Matlab in my simulation. I notice a small bug(probably) in the IDE,
when I try to include some libraries in the path, like /Matlab/extern/
include, these aren't correctly added to the simulation but should be
manually added inside the makefile through -I option.

heyy friends ... how u did that (integration of matlab with omnet++ )?? is there any plug in for that ?? please help 

[Asma Djaidri]

is it that possible?? please can you tell us how did u do that??

Hai Sir,

      Can you please share the details of how you implement the integration of matlab and omnetpp? Expecting your reply. Thanking in advance.

Using TCP, you can send the data that you need to process to matlab using TCP

You can use Posix sockets in Omnet++ and Matlab sockets in Matlab, but you need to be careful with the Matlab TCP implementation, by default it uses network byte order to send the data, you need to configure the information to little endian.

For posix sockets you can use the book of Richard Stevens "Advanced Programming in the UNIX Environment, Third Edition"

For Matlab

https://es.mathworks.com/help/instrument/communicate-using-tcpip-server-sockets.html

Communicate Using TCP/IP Server Sockets - MATLAB & Simulink - MathWorks España - Makers of MATLAB and Simulink Communicate Using TCP/IP Server Sockets About Server Sockets. Support for Server Sockets is available, using the NetworkRole property on the TCP/IP interface. This support is for a single remote connection. es.mathworks.com

To change the byte order

t = tcpip('0.0.0.0', 30000, 'NetworkRole', 'server');

t.ByteOrder = 'littleEndian';
fopen(t);

Hi Sir, how can we use the tcp ? i have some measurement data in matlab and i want to send them to omnet++ to propagate them in a wan how i can do that?

hello  i am trying to send data from matlab to omnet++ using tcp socket and i am new to omnet++. can you give me some links from where i can learn about how to do send data from matlab to omnet++ using tcp socket. thanks.
