Vehicular Ad-Hoc Networks (VANET)

Vehicular ad-hoc networks (VANETs) technology has emerged as an important research area over the last few years. Being ad-hoc in nature, VA NET is a type of networks that is created from the concept of establishing a network of cars for a speci�c need or situation. Vehicular ad hoc networks (VANETs) are an important communication paradigm in modern-day mobile computing for exchanging live messages regarding traffic congestion, weather conditions, road conditions, and targeted location-based advertisements to improve the driving comfort. Along with the benefits, there arise a large number of challenges in VANET such as provisioning of QoS, high connectivity and bandwidth and security to vehicle and individual privacy. This article presents Network architecture, signal modeling and, routing protocols and network security and, a comparative test of various mobility scenarios of Vehicular Ad-hoc Network in three well-known Indian Metros. The AODV routing protocol have been used for the simulation.
