Implementation Requirements for the Notice Architecture in Vehicular Communications

Many studies have been focusing on Vehicular Ad-Hoc Networking (VANET) in order to increase the quality of traffic and life on the road. An important aspect in vehicular communications is maintaining the privacy and security of VANET. NOTICE is an emerging architecture promising efficient traffic notification as well as strong immunity to malicious attacks, leading to improvement of safety and reduction of traffic congestion on roadways. To enable secure traffic notification, the NOTICE system employs vehicle-to-infrastructure (V2I) communication rather than vehicle-to-vehicle (V2V) communication like in traditional VANET. The infrastructure consists of sensor belts which are embedded in the roadway and used to accumulate and confirm traffic-related information reported from passing vehicles. In this thesis, we investigate various parameters regarding successful communication between vehicles and sensor belts which are vehicle velocity, traffic flow, connection setup time, available time for handshaking and data exchange, data rate, amount of data, and communication range in order to provide some perspectives for the physical layer of the NOTICE wireless communication. Empirical simulation and theoretical analysis are performed in comparison. Results of this thesis have been presented at the 2nd International Workshop on Mobile Vehicular Networks (MoVeNet 2008) and published in the IEEE Mobile Ad-hoc and Sensor Systems (MASS) proceedings [1].
