Previous work has shown that well-established discrete-event network simulators tend to follow the technology evolution, even if with some delay that might extend up to a full year, when it comes to making new capabilities available to simulate new technologies. Moreover, trying to extract the required results from a plethora of modules built one over the other alone takes a fair amount of time, frequently becoming a research bottleneck. Thus, this work proposes a new foundation for a simulator that will eventually catch up with the 5G and 6G technology, aiming at providing easy insight into the metrics that might be required for providing results for scientific work. And, as a first test-case scenario, a 5G network comprised of base stations and user equipment is simulated using the Round Robin and the Proportional Fair schedulers to provide a comparison of delays and starvation metrics, proving the simulator works and is ready to be extended by including new technologies such as mmWave, Integrated Access and Backhaul, network slices, and all that comes next.
