WiLabV2Xsim is a dynamic simulator, written in MATLAB, overhauling LTEV2Vsim (see https://github.com/alessandrobazzi/LTEV2Vsim) to support sidelink 5G-V2X. It is designed for the investigation of resource allocation in networks based on sidelink C-V2X, with focus on the cooperative awareness service, but it also allows to simulate IEEE 802.11p/ITS-G5.

The simulator is shared under the GNU GPLv3. The software has been developed and shared by University of Bologna, CNR, and WiLab/CNIT - Italy.

The first release of this simulator is version 6.1 to remark the continuity with LTEV2Xsim, of which the last shared version was 5.4.

From version 5.4 to version 6.1 the main modification is the addition of 5G-V2X, with NR and all the related settings (including numerology). A general refactoring was performed to generalize the parameters which are common for LTE and 5G, now indicated as CV2X. Minor corrections and improvements were also performed.

NOTICE: The code runs correctly with Matlab versions from 2021b at least. There are problems with version 2016b and earlier. With the versions in between, some minor corrections would be required (we haven't checked all the versions). The Statistics and Machine Learning Toolbox™ is needed for the simulation and generation of 3GPP a-periodic traffic.
