A Novel Headway-Based Vehicle-to-Vehicle Multi-Mode Broadcasting Protocol

We propose a novel application adaptive (multi-mode) headway-based broadcasting protocol that is most appropriate for public-safety applications in VANETs. Being headway-based, the proposed protocol possesses unique robustness at different speeds and traffic volumes. Moreover, it addresses application differences with a new multi-mode feature. The logic behind the new concepts/approaches adopted in the protocol and their merits are highlighted, supported with analysis and simulation.
