[BonnMotion] feedback on 3D scenarios generation and format conversion

Wed Jan 15 15:31:19 CET 2020

Hi Oscar,

I‘m afraid there are no plans to change the RPGM model implementation since we try to adhere to the original papers.

Concerning your other question, I’m not familiar with any generators for swarm mobility.

Google came up with some paper suggestions (cf. [1], [2]), however.

If these are of interest to you, you might want to ask the authors for any code or you could even implement the models yourself.

Best regards,

Matthias

Hello Matthias,

Thanks for replying, I was just thinking in sending an email, today afternoon or tomorrow to know if you were able to replicate the behavior.

Yes I have used it to generate 2D scenarios with RPGM and it works fine, nonetheless I am currently working on swarm-of-drones applications, therefore I need 3D scenarios.

By the way, regarding 2D scenarios, I sometimes observe that some nodes move really close to other nodes, while there are some nodes very far (near the limit of the maximum distance set as parameter), I wonder if there is under development or at least the idea of a movement pattern that maintains a minimum distance between nodes that can be flexible, this is, that it is not strictly necessary that two nodes maintain that minimum distance, but that tries to be satisfied in order to maintain a better distribution of nodes in the space at all times.

Also I would like to take this opportunity to ask you - for sure you know more people in this field - if there is any swarm mobility scenario generator or at least sample scenarios that is open for use by other researchers, I have been struggling with using a good 3D scenario with mobility and I believe someone already did it, but probably is not for open use.

Have a good day !

Best,

Hi Oscar,

sorry for my late reply. I’m afraid RPGM does not support 3D. The only mobility model that currently does is RandomWaypoint.

Have you tried creating a 2D scenario with RPGM?

Best regards,

Matthias

Hello Dr. Matthias,

What a quick response, great !

Ok so, I am using Ubuntu 18.04.3 LTS, BM version is 3.0.1

I created a quick example, using attached gm3dbase.params file as a start, and used the following command lines:

To generate the 3D scenario:

./bm -f whatever -I gm3dbase.params RPGM

There you can see negative Z values.

To convert the scenario to NS-2 format:

./bm NSFile -f whatever -b

I am attaching the whatever.ns_movements generated from BM and also a file that I obtained using a converter that I wrote, the issue is in the speed values.

Thanks!

Kind regards,

Oscar Bautista

Hi Oscar,

I’m happy to hear you’re still using BonnMotion despite the sporadic releases.

Although the last release date is indeed somewhat old, BonnMotion is actually still being worked on.

You might have noticed, based on the even older release dates, that new releases tend to take their time.

In order to replicate your problems, could you please provide more information, such as

-        system environment

-        BM version

-        command lines you used

Thanks.

Best regards,

Matthias

Hello,

I have been using BonnMotion for a while now as a base to generate 3D scenarios and I noticed some issues. Although it seems to me that this project is no longer updated based on the last release date, I would like to try to convey these findings. This mobility scenario generator has been useful to me that I would like it to improve.

The issues:

I have used just RPGM, and because I need 3D scenarios I specify the Z coordinate, the resulting scenario has negative Z values.

The tool NSFile to convert BM scenarios to NS-2 format does not work correctly when the node has several waypoint not just two.
