Wireless communications are becoming the dominant form of transferring information, and the most active research field. In this dissertation, the authors will present one of the most applicable forms of Ad-Hoc networks; the Vehicular Ad-Hoc NETworks (VANETs). VANET is the technology of building a robust Ad-Hoc network between mobile vehicles and each other, besides, between mobile vehicles and roadside units. Traffic maintenance in highway using broadcasting protocol is a new theme. It is important to find a reliable broadcasting protocol that is especially designed for an optimum performance of public-safety and data travelling related applications. Using RSU and OBU, there are four novel ideas presented in this paper, namely choosing the nearest following node as the network probe node, headway-based segmentation, non-uniform segmentation and application adaptive.
