About Ns3 leo module

[March2k25]

Hi everyone, I am currently working on a project and need information on how to simulate this specific module. I would appreciate your help. Thank you in advance.

Hello March, long time no see. I was working on NS3.

NS3-LEO MODULE? about the installing or what's the help you need?

[March2k25]

about installing im ok i think , but to work on a project it is making difficult like which modules i should use and simulate and i hope anyone can colaborate with my idea to produce a research paper.Thanking you in advance

its ns leo module 

[Raouane Dehimi]

i would like to know more about your implementation exactly so i can help

Hey hi Raouane Its a research paper . Its about semantic clustering in satellites 

[Raouane Dehimi]

From my perspective, you should:

1. Select the semantic feature that you want to cluster.

2. You can either cluster in Python and connect to ns-3 (using ns3-ia to exchange data between ns-3 and Python ML frameworks) or you can cluster entirely inside ns-3.

Hello March2k25 and all,

I have been watching this thread for the last few days. I want to share my views on this.

While the ns-3 LEO module features a robust Mobility Model capable of handling orbital dynamics, many of its lower-layer components—such as the NetDevice and Channel—are only provided as abstract "mock" implementations.

For researchers focused on Network Layer (Layer 3) routing, these abstractions are often sufficient. Since the Mobility Model correctly handles satellite positioning, you can utilize the mock-net-device and mock-channel to exchange packets according to your specific logic. To conduct this research, you must integrate a custom routing module into the ns-3 stack, implementing your unique algorithms while leveraging the existing mobility framework.

However, a significant gap exists between academic theory and orbital reality regarding clustering-based routing:

• The "Paperware" Trap: Conventional clustering models found in academic literature, such as LEACH, are essentially "battery killers." While they are frequently cited, they are notoriously inefficient and rarely perform well in terrestrial wireless sensor networks, let alone the extreme environment of a LEO constellation.

• Modern Industrial Clustering: It is a fact that modern satellite networks utilize clustering-based routing, but not in the way early sensors did. Practical LEO networks rely on Software-Defined Networking (SDN) to manage clusters. Unlike the decentralized, high-overhead "elections" seen in older protocols, modern systems use centralized ground-based orchestration to manage handovers and energy distribution.

I hope these insights help with your research.
