Simulation of Next-generation Cellular Networks with ns-3: Open Challenges and New Directions

Abstract

One of the main strengths of Network Simulator 3 (ns-3) is the availability of modules to simulate cellular networks, including LTE and mmWave/NR deployments. These implementations model the protocol stack with a high level of detail, and, thanks to the integration with the whole ns-3 code base, make it possible to study end-to-end scenarios and identify complex interactions between the different components of a network. In this white paper we discuss the current limitations of this platform, and suggest directions for future work that could improve the accuracy of the simulations.
