A Comparative Study of IEEE 802.11 Standards for Non-Safety Applications on Vehicular Ad Hoc Networks: A Congestion Control Perspective
Vehicular Ad-hoc NETworks (VANETs) is an important component within the Intelligent Transportation Systems (ITS) that have been part of global strategy and advanced applications. The aim is to provide innovative services relating to various modes of transportation and traffic management. These systems enable users to reach their destinations better, safer and more coordinated. In order to make the system workable, several Radio Access Technologies (RAT) such as UMTS, Wi-Fi, WiMAX and radio spectrum at 5.9 GHz have been proposed for next generation ITS. In this paper, the authors investigate the IEEE wireless standards for non-safety applications in a distributed VANET.
