In this project, the development of novel communication models for Car2X communication is the main goal. The idea is to develop a simulation framework which can cope with the heterogeneous nature of Car2X communication. The development of specialized Car2X nodes which consider safety and security aspects are also part of the subproject. With respect to the latter, we are developing an optimized hardware-software architecture, based on multicore architectures and hardware accelerators. The project results will be validated by a joint demonstrator.
