The use of wireless communication to provide inter-vehicle communication promises more safety and comfort for vehicle passengers. In this thesis protocols for secure and scalable inter-vehicle communication, trust architectures, and architecture solutions for vehicular networks are suggested and evaluated. Concepts like dissemination areas and context-based packet prioritization are introduced and evaluated using a network simulator. In addition, the use of trust architectures and reputation mechanisms in decentralized VANETs is evaluated. The results on communication and security mechanisms are combined in an architecture concept, providing decentralized message dissemination as well as centralized service provisioning. The presented results will help to understand the complex challenges of vehicular networks and point out possible approaches to come to an unified system architecture.
