Abstract

Vehicular ad hoc networks (VANETs), a subset of mobile ad hoc networks (MANET), holds great potential for the advancement of intelligent transport systems (ITS). VANET enables vehicles to establish a self-organized network without the requirement of a permanent infrastructure. With its potential to enhance road safety and provide real-time traffic updates, as well as other travel conveniences, the VANET has captured the interest of researchers. Though VANET and MANET shares some common characteristics like self-organized network, dynamic topology, ad hoc nature etc., VANET differs from MANET by challenges, application, architecture, power constraint and mobility patterns, so routing protocols used in MANET are not applicable with VANET. Many researchers have proposed a new routing strategy for VANET in recent years. This paper primarily focuses on the different aspects of VANET, including its architecture, unique characteristics, challenges it faces, insights into routing protocols, and simulation models used for its development.
