Application-Aware Opportunistic Routing Protocol for Traffic Violations Notification in Internet of Vehicles

Vehicular networks are an emerging type of net-works used in several applications in Intelligent Transport Systems and Smart Cities. Recently, the set of these applications has been extended to include even more with the emergence of the connected vehicles and the Internet of Vehicles (IoV). To make these different applications work effectively, wireless communications are required between the various nodes of the network. Specifically, it is important to find an efficient way to route messages from a source node to a destination node. In this paper, we propose to adapt the well known opportunistic routing protocol PRoPHET to send a notification of traffic violation in order to help the traffic policemen in their job. So, the application installed in an OBU, RSU or smartphones broadcasts a hello message with its identification at each time interval and each vehicle receiving this last calculates the probability of encountering these nodes. This last represents the delivery predictability for the application. To evaluate our proposition, we present a case study with the application of the traffic violations notification in the Algerian city of Bejaia. We create a simulation scenario for our application in the ONE simulator and evaluate the latency, the overhead rate, the delivery probability and the number of hops using PRoPHET and Epidemic opportunistic routing protocols.
