5G-LENA: The 5G NR module for the ns-3 simulator

ns-3 module to simulate 3GPP 5G networks

5G-LENA is an open-source 5G New Radio (NR) network simulator, designed as a pluggable module to ns-3. Its development, initially funded by InterDigital, is open to the community under GPLv2 license in order to foster early adoption, contributions by industrial and academic partners, collaborative development and results reproducibility.

The 5G-LENA simulator enables end-to-end simulations from the application layer down to the physical layer and thus provides invaluable insights into the design of industrial 5G solutions and allows early assessment of the potential performance of such solutions.

Inherit the strengths of ns-3

ns-3 is an open source discrete-event network simulator/emulator. The ns-3 project is committed to build a solid, well documented, easy to use and debug simulation core, which caters to the needs of the entire simulation workflow, from simulation configuration to trace collection and analysis.

Compared to other open source simulators, ns-3 offers multi-RAT (Radio Access Technology) and multi-band simulation capabilities, in which multiple technologies can operate and coexist: NR, NR-U, LTE (LTE-A, LAA, LTE-U) Wi-Fi, WiGig, etc.

Born in academia

5G-LENA is being designed, developed and maintained by the Open Simulations research unit (OpenSim) of CTTC (Centre Tecnològic de Telecomunicacions de Catalunya). OpenSim research group maintains a strong commitment with the ns-3 community in the areas of NR, NR V2X, NR-U, O-RAN, LTE, and its evolutions.

The extensive study and calibration of the 5G-LENA models, showcased in numerous peer-reviewed publications, establishes it as a reference 5G NR simulator for conducting comprehensive and in-depth research.
