An Emergency Wireless Communication Framework for Vehicular Networks

An Emergency Wireless Communication Framework for Vehicular Networks:

This project investigates the integration of suitable wireless technologies in vehicular networks for forward upcoming traffic information with the least possible delay in order to improve traffic safety. The 2012 National Highway Traffic Safety Administration (NHTSA) report claims that in the US alone one person dies in a vehicle crash every 15 minutes. Additionally, traffic congestion and collisions cause losses totaling billions of dollars in fuel and lost worker productivity. If drivers could get real-time traffic information ahead of time, it could help prevent most of the collisions, helping to save lives, prevent injuries, and reduce the cost incurred due to traffic congestion.

Delivering real-time traffic information to drivers through wireless communication in vehicular network can assist in avoiding traffic accidents and congestion. The selection of wireless technology depends on the application that the vehicular network is envisioned to support. For time-sensitive emergency messages, V2V based communication is suitable whereas other messages could be transmitted using V2R communications. Furthermore, ZigBee, Wi-Fi and Bluetooth devices operate in unlicensed bands and DSRC (802.11p), devices operate in dedicated band where vehicular users do not have to pay for any licensing fees as in the case in cellular systems
