Simulation of Satellite environment

[Radhakrishnan Subramanian]

I wish to simulate Satellite environment for LTE. Konstantinos responded to one of my posts advising me to get in touch with a company who are doing some work in Satellite integration with NS3 code. I sent a mail to them but they did not respond.

In NS2 there is a satellite code. How much of this code is directly usable or can be customized to NS3 environment?

Is there a difference between GEO and LEO satellite environment parameters?

I have identified some parameters apart from RTPD which are

Propagation abnormalities effecting Satellite Communication Links
Ionospheric Effects
Tropospheric Effects
Local Effects
Probability Distribution Functions for Different Types of Fading 
 Rayleigh Distribution
 Rician Distribution
 Log-Normal Distribution
 Nakagami Distribution
Statistical Channel Modeling of Land-Mobile-Satellite Communications
 Single-State Models
 Multi-state Models

Are there some more to be considered? I shall be happy to implement code for some of these with your guidance.
My interest is to develop a satellite environment to work with LTE and characterize the same. That is part of my doctorate indeed.

Can experts advise?

Try again, perhaps they're closed for the holidays.

Practically nothing. You can use it as a guideline, but it's not directly usable.

 

Is there a difference between GEO and LEO satellite environment parameters?

Err... yes. They're completely different environments, with completely different propagation and error effects. Basically it's like comparing a car and a train. They're both vehicles, with wheels and they have passengers,but other than that they're completely different.

For the LEO case you should also consider the handover between satellites (because the satellites are moving), the doppler effect, the varying RTT and the Inter Satellite Link routing toward the earth gateway station.

I'd really keep poking the guys Kostantinos told you about. They're really busy and it's holiday time, but they will answer you.

One of the possible issues is the code availability, as it's not yet "public". However, I'm sure that they'll give you some feedback, at least to avoid code duplication.

Cheers,

Hi Radhakrishnan --

I helped to co-found Alanax Technologies, which specializes in the modeling & simulation of aerospace communication networks.  Did you try to get in touch with Alanax?  See www.alanax.com.

The propagation loss effects that you mentioned, including atmospheric absorption through all layers of the atmosphere, rain & cloud losses, tropospheric scintillation, doppler shift, and the changing transmitting and receiving antenna gains in the link directions as objects move through space and time are all modeled with high-fidelity in a commercial tool called STK.  Alanax has a solution that allows ns-3 to use the STK physical-layer models for specified links in the ns-3 topology.

Feel free to send an email to in...@alanax.com if you'd like more information about this solution.  I think it's probably what you are looking for.

I sent a mail to the SNS3 company requesting them for the code.

Hello,
             I am doing doctorate in the field of Satellite LTE. I was using NS3 for the simulations. This requires satellite interfacing. Looks like you are developing some code to be integrated with NS3. How far is this code ready and can you share this with me?
              Konstantinos  and Tommaso Pecorella of NS-3 advised me to get in touch with you for this software. Can you please share this software? I shall be able to contribute if something is needed.

regards and thanks,
S.Radhakrishnan,

Hi Radhakrishnan,

did you eventually get an update from them? I am equally interested as i am working on a similar research. if you can, kindly share with me as well. thanks

Beta copies of STK Networking, which supports integration between ns-3 and STK, are available from Alanax as of this week.  Please send an email to in...@alanax.com for a trial copy.

[Radhakrishnan Subramanian]

There is no Satellite code released as of yet. I sent a mail to them but still not much progress.
Can someone help here?

Hello

Is there anyone has used NS3 to do a simulation of satellite? Is there any public satellite module?
thanks

[Konstantinos]

Dear Leonardo,

Please DO NOT spam the list with the same question. 

If you had read the threads you posted, you would have found a link to the available satelite module (http://satellite-ns3.com/)

and the details theirin.
