A hybrid routing protocol for vanet using ontology

Abstract

Vehicular Ad-hoc NETwork (VANET) is a wireless communication technology applied to transportation, its main objective is to improve road safety, logistics and information services. However, the efficiency and performance of VANET applications depends primarily on the way in which messages is transmitted between the vehicles, but the major challenge is to find a routing protocol adapted to a highly dynamic environment such as VANET. So the proposed solutions must take into account the specific characteristics and constraints of VANET, such as speed, acceleration, geographical position, the transmission radius, management, etc. In this paper, we propose an approach using ontologies and vehicle traffic information to ensure the transmission of packets as soon as possible and in the most reliable way.
