Abstract(s) :

(Anglais) Nowadays a novel satellite communication solution has to be introduced for the coming satellite networks. Software Defined Networking (SDN) and Software Defined Radio (SDR), can play a key role to innovate and improve satellites-terrestrial communications. GNU radio as SDR and Mininet as SDN, offer the ability to manage the network satellite resources. Through scenario and use cases, this paper provides an in-depth analysis for an effective combination of SDN,GEO, and LEO satellites using GNU Radio simulation and Python3 scripting. This new architecture can bring satellite communications towards a new proposal of data transmission technology to delimit the various potential areas of improvement. That can be pursued by the added value of SDN-GNU Radio technologies in the field of the satellite ground segment. To achieve this result, the newly introduced architecture can be fully controlled at the physical layer level. The solution is validated by the deployment of three scenarios: with SDN, without SDN, and SDN adding a streaming overload. Based on the results of the presented simulation, we found that our architecture can achieve better quality of service through efficient satellite traffic control, when SDN and GNU Radio are deployed.
