Comparative study of LTE simulations with the ns-3 and the Vienna simulators

Abstract

In this paper we compare two simulators: ns-3 and Vienna, in the context of LTE networks, on four basic scenarios for which well-known analytical results exist. These scenarios differentiate themselves by the nature of the traffic (data or voice) and by the number of sources (infinite or finite). Our goal is twofold. First, by confronting the results of the two simulators with exact results, we can assess the accuracy of both simulators and compare their efficiency. Second, and maybe more importantly, we want to compare the ease of handling and use of both simulators, and list the difficulties encountered in the context of the four basic scenarios, that will necessarily arise in more realistic simulated scenarios, and explain how we worked around the problems. We hope this comparison will help researchers who work on LTE networks to choose the simulator that best suits their needs.

“…Several works in the literature use the discrete-event simulator on ns-3 network [53] and the LTE-EPC Network Simulator (LENA) module [54]. It is pointed out that the ns-3 simulator has already been validated for the LTE module and has been indicated as the best choice for complex scenarios, as demonstrated by [55]. Completing for the scope of work, the Keysight Technologies is a company that provides tools for 5G signal modulation, such as the Advanced Cellular Pack for Simulation and 5G Protocol R&D Toolset [56].…”
