Abstract

Objectives: To analyze the performance and to determine the most suitable routing type, to ensure the best efficiency in the VANET. Methods/Statistical analysis: Vehicular Ad Hoc Networks (VANET) constitute one of the most promising areas of application of ad hoc wireless networks, able to organize without predefined infrastructure. These networks allow vehicles to communicate with each other or with the roadside infrastructure and will ultimately have safer and more efficient roads through the exchange of timely information to drivers and authorities. Findings: The routing information in VANETs is a major challenge because they are characterized by high mobility resulting in a highly dynamic topology. In this article, we present the most popular routing protocols, offered to do the routing. We describe their main features and functions that ensure the flow of data between different mobile units. We are particularly interested in the problem of delay and bandwidth consumption in routing protocols. In this axis, we compare the various recent proposals for routing protocols to determine the most efficient routing types. This article gives readers a deeper insight on the methods proposed in this area and the most effective solutions to improve VANET. Applications/Improvements: The results observed from this paper motivate to improve the stability of cluster structure in clustering routing protocols in VANETs.
