A Secure and Privacy Aware Data Dissemination For The Notification of Traffic Incidents

Recently, Vehicular Ad-hoc Networks (VANETs) employing a combination of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) wireless communication have been proposed to alert drivers about different traffic events. NOTICE, a secure and privacy-aware architecture for the Notification Of Traffic InCidEnts that provides drivers with up-to-the-minute notification about highway conditions, is introduced in. NOTICE moves the responsibility for making decisions about traffic-related incidents to the infrastructure rather than leaving those decisions with the vehicles, which may have incomplete or incorrect knowledge. This paper introduces a secure data dissemination technique that could be used in NOTICE or can be easily adapted to enhance other existing data routing or dissemination techniques.
