How to Implement Inter Planetary Networking in ns3

To implement Inter planetary networking in ns-3 by simulating the network with extreme high latency. Our team of researchers conducts high-quality comparative analyses on all concepts of Interplanetary Networking using NS-3. Below steps will guide on setting up a basic simulation of Interplanetary Networking using NS-3:

Step-by-Step Guide to Implement Inter Planetary Networking in ns3:

Step 1: Install ns3

Ensure that ns3 is installed on the system. Follow the installation instructions provided there.

Step 2: Understand DTN and Bundle Protocol

Previously on implementing, it’s important to understand that traditional TCP/IP protocols are inadequate for interplanetary distances due to tremendously high latency and frequent link disturbances. DTN with the Bundle Protocol allows for store-and-forward communication, which stores data packets at in-between nodes until the link becomes accessible.

Step 3: Check for DTN Implementation in NS-3

NS-3 does not natively support DTN or the Bundle Protocol out of the box. We need to either find a third-party implementation or develop an adaptation. Here we will the latest NS-3 contributions and third-party modules for any updates on DTN aid.

Step 4: Simulate Basic Network Setup

Incase , If you find or progress a DTN module for NS-3, the next step is to simulate a basic network setup. Here’s how you might set up a simple network topology without specific DTN protocols, which needs to be modified once you have the suitable modules.

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/point-to-point-module.h”

using namespace ns3;

int main() {

    NodeContainer nodes;

    nodes.Create(2);

    PointToPointHelper pointToPoint;

    pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“512Kbps”));

    pointToPoint.SetChannelAttribute(“Delay”, StringValue(“2s”));  // High delay to simulate space communication

    NetDeviceContainer devices;

    devices = pointToPoint.Install(nodes);

    InternetStackHelper stack;

    stack.Install(nodes);

    Ipv4AddressHelper address;

    address.SetBase(“192.168.1.0”, “255.255.255.0”);

    Ipv4InterfaceContainer interfaces = address.Assign(devices);

    Simulator::Run();

    Simulator::Destroy();

    return 0;

}

Step 5: Implement DTN Functionality

Should have a secured DTN module for NS-3 or built one:

  • Integrate the DTN module in your NS-3 simulation.
  • Set up Bundle Protocol handlers and configure DTN nodes to handle long delays and intermittent connectivity.
  • Use store-and-forward mechanisms where nodes can store data until a communication path is available.

Step 6: Testing and Validation

Run various scenarios to validate the DTN implementation:

  • Test with different orbital configurations and communication windows.
  • Simulate disruptions and measure how effectively the DTN protocol recovers and forwards data.
  • Analyze performance metrics such as delivery ratios, latency, and throughput under varying conditions.

Step 7: Enhance with Realistic Space Communication Models

For more realistic simulations:

  • Incorporate models that simulate the movement of planets and space vehicles.
  • Adjust the propagation delay dynamically based on the positions of the communicating entities.

Overall, we have learnt to implement the Inter planetary Networking in ns3 environment by understanding DTN and Bundle protocol.
