Vanetza is an open-source implementation of the ETSI C-ITS protocol suite. This comprises the following protocols and features among others:

  • GeoNetworking (GN)
  • Basic Transport Protocol (BTP)
  • Decentralized Congestion Control (DCC)
  • Security
  • Support for ASN.1 messages (Facilities) such as CAM and DENM

Though originally designed to operate on ITS-G5 channels in a Vehicular Ad Hoc Network (VANET) using IEEE 802.11p, Vanetza and its components can be combined with other communication technologies as well, e.g. GeoNetworking over IP multicast.

How to build

Building Vanetza is accomplished by the CMake build system. Hence, CMake needs to be available on the build host.


You need following tools and libraries on your system for compiling Vanetza:

If OpenSSL (1.0 or 1.1) or LibreSSL is available on your system, an alternative security backend implementation is compiled along with the Crypto++ based backend. See security::Backend and security::create_backend for more details.


Following command line snippet demonstrates the build process using a generated Makefile. Other CMake generators and build directory setups can be used as well.

cd vanetza
mkdir build && cd build
cmake ..

Continuous Integration

We strive for quality in our code base. Latest commits are built using Travis CI as part of this effort. Build Status


Vanetza ships with a simple demo application called socktap. You can enable the build process for this application by the BUILD_SOCKTAP CMake option. See tools/socktap for details. If socktap is going to be built gpsd is required in addition to aforementioned prerequisites.

Integrating Vanetza

Vanetza is primarily a library project intended for integration by other projects, e.g. V2X simulation tools such as Artery. Projects using CMake can integrate Vanetza most easily by calling find_package(Vanetza) and then refer to the imported Vanetza targets, such as Vanetza::vanetza.


Development of Vanetza is part of ongoing research work at Technische Hochschule Ingolstadt. Maintenance is coordinated by Raphael Riebl. Contributions are happily accepted.
