Comparative analysis of proactive and reactive routing protocols in VANET environment

Abstract

VANET (Vehicle Ad hoc Network) is a subclass of MANET, which is a rapidly increasing research field in the world. Vehicles are interactive with each other, V2I & hybrid in VANET. Several difficulties are facing author’s today V2V, V2I, and hybrid communication. Vehicles usually turn the field of VANET communication, transparent and enter new vehicles, network size or street conditions are main elements of this communication, which poses particular challenges such as highly dynamic topology, unregulated network size, high mobility, scalability, and networking. The previous MANET protocols are not enough to help VANET as a result of these issues. In this study, we surveyed and published numerous classes of VANET routing protocols (VRPs). Comparing the different classes of VANET protocols gives guidelines in one place. In this work, we utilize network simulator 3 to apply AODV, DSDV & OLSR routing on V2V, nodes. The evaluation criteria for comparison of these routing protocols include the use of QoS (Quality of Service) parameters such as PLR, packet overhead & throughput. For simulations, we use IEEE 802.11p model. The results of the simulation demonstrate that AODV is the most optimal method among AODV, OLSR & DSDV for our model.
