An examination of routing protocols in vehicular ad hoc networks (VANETs)

Abstract

Due to network and wireless technology advancements, researchers have been interested in vehicle ad hoc networks (VANETS) for decades. Vehicular ad hoc networks (VANETs) have replaced MANETs. VANETs improve safety and comfort by connecting on-road automobiles to roadside equipment. Due to the dynamic nature of VANETs, there is no optimal routing method for each application. Most current research focuses on security, routing, and quality of service. Routing algorithms, services, and the optimum mobile network design need further study. To propose a new routing method or update an existing one, one must have a detailed grasp of past routing protocols. This paper reviews VANET routing methods and their benefits and cons. This poll will aid academics studying VANET routing and proposing new methods. This article compares routing methods using several criteria in the final section. This comparison helps clarify each protocol's applicability.
