can't find " ns3/epidemic-routing-module.h" #3

Thanks for all you have done, I'm working on import this module into ns3, but there's something wrong when running examples, the fatal error is " fatal error: ns3/epidemic-routing-module.h: can't find this document or menu". Can you just help me figure it out? I suspect that maybe the version of ns3 and ubuntu results that error, I'm using ns3.34 and ubuntu18.04, can you tell me the limits of version? Or where can I find "epidemic-routing-module.h“？ By the way, I'm tring to use this module to product datasets for satellite routing, can I modify this module to make it?

Sorry to disturb you, I have already found this module. And I wonder have you or anybody else ever tried to apply this module with ns3-gym for satellite routing optimization? Thanks a lot for all you’ve done.

Sorry, for the late reply. Glad you could resolve your issue.

Not that I know of, but I don't currently follow the research in this field. So there might be something I do not know of. The satellite positions / link metrics are time-dependent but also very deterministic. So I would assume the most effective way would be to centrally compute routes based on the current / expected traffic patterns in the regions and known satellite positions. This may be done using reinforcement learning, or conventional routing algorithms (Dijkstra) using the appropriate metrics.

Dear Tim,

thanks for your reply, I totally agree with you, and ns3-gym is just specifically designed for reinforcement learning, it provides an interface so that ns3 can work as the environment with agents written in Python. But I’m a little confused after reading the example of “leo-delay-tracing”, it seems like we can only get the delay from one ground station to another(which is defined by setting altitude and longitude), satellites are defined as “constellation”, but as you say, I just want to research the routing metrics of ISL, can you guide me how to make it? Sincerely thank you again for your help.
