Abstract
Over the last several years, vehicular ad hoc networks (VANETs) have emerged as a critical research field. VANETs are a sort of network that is ad hoc in nature, and they are derived from the notion of building a network of automobiles for a given purpose or scenario. VANETs, or vehicle-assisted networks, have now been created as dependable networks that cars may utilize for communication on roads and in metropolitan areas. While VANET offers many advantages, it also faces a number of issues, namely providing quality of service (QoS), maintaining vehicle security and individual privacy, and offering high connectivity and bandwidth. This review article provides an overview of VANET technology’s current state and addresses the issues that it faces. This section summarizes the findings of the many studies that have been done in this field to date. The following topics are treated in depth: network architecture, signal modeling and propagation mechanics, mobility modeling, routing protocols and network security.
