Saying "Happy New Year" in ns-3 way

[Charles Pandian]

Dear ns-3-users,

Even though I am not civilized enough to say "wish messages" to people, let me try to deliver a "Happy New Year"  wish message to the members of  ns-3 user group and the ns-3 developers in an ns-3 way.

A Python Script for Generating an ns-2 Mobility Trace File

A python script was from the ideas mentioned in [4].  This python script will convert a text message into appropriate node locations and create a mobility scenario file from it. The nodes are started to move from a random location and finally form a text message at the end of the mobility.

You can see this python script at the following link:

ns-3 Drone Display Simulation using ns-2 Mobility Trace File

Or you may simply download the attached mobility file (mobility.txt) and use it along with the following simulation.

A Simple ns-3 Simulation for Drone Show

The following ns-3 simulation script presents the idea of creating a 'drone show' using ns-2 mobility trace file.

#include "ns3/core-module.h"
#include "ns3/mobility-module.h"
#include "ns3/ns2-mobility-helper.h"
#include "ns3/netanim-module.h"

using namespace ns3;

int main (int argc, char *argv[])
{
// Create Ns2MobilityHelper with the specified trace log file as parameter
Ns2MobilityHelper ns2 = Ns2MobilityHelper ("mobility.txt");
// Create Moble nodes.
NodeContainer MobileNodes;
MobileNodes.Create (464);
// configure movements for each node, while reading trace file
ns2.Install ();
AnimationInterface anim ("SimpleNS3DroneShowSimulationWith-ns2-mobility-trace.xml");
Simulator::Stop (Seconds (100));
Simulator::Run ();
return 0;
}

 

See the attached gif animation of the NetAnim Ouput.

The following is the 3D output of a  scenario under NetSimulyzer :

This idea can be used to design and test automated drone shows under ns-3 simulator.

Finally, thank you,  Mr. Tom and other Developers as well as the Contributors of ns-3 for their generous contribution to ns-3 community.

  😊Happy New Year 2022.😊

This is fascinating!

Happy New Year, fellow ns-3 users!

Really it's amazing. Happy new year to you too.

Kindly share more knowledge about mobility as I need to work on it. 

Plz suggest readings/videos and codes for better understanding.

You may find my implementation of CircleMobilityModel at my Merge Request 821 at ns3-dev.
https://gitlab.com/nsnam/ns-3-dev/-/merge_requests/821

you may read about its implementation details and another model on my blogs:

Hi Charles,

Plz help me to suggest a way to implement mobility on a single node around the grid. 

Thanks in advance
