SatSysSim: A Novel Event-Driven Simulation Framework for DVB/RCS2 Performance Characterization

Satellite networks are expected to perform a vital role in future communication systems, with complex features and seamless integration with ground-based infrastructure. This paper presents a novel simulation framework capable of providing a detailed assessment of a satellite communication’s network performance in realistic scenarios. The proposed framework employs an event-driven methodology, models the communications network as a DES (discrete event system), and focuses on the return link of the DVB-RCS2 standard. Three different scenarios demonstrate possible uses of the simulator’s outputs to understand the network’s dynamic behavior and achieve optimal system operation. Each scenario explores different features of the simulator covering a large territory with thousands of users, which in our case study was the country of Brazil.
