Hardware Implementation of VANET Communication based Collision Warning System

Vehicle and passenger safety is one of the key attributes in designing autonomous vehicles. Vehicles are equipped with several fast computing devices and sensors that will alert the driver in risk conditions, but there are events that cannot be identified by such sensors, such as road intersections. In such conditions, data collected from other devices or vehicles can help. Vehicular Networks ensure the safety of these by enabling the communication between the vehicles. The ideal scenario about Vehicular ad-hoc Network is, where the vehicles on the road are connected to each other and to RSU devices, details about their transit are transmitted to the manipulating devices. The objective of this work is to simulate such a condition via NS2 simulator and to implement the hardware prototype of such scenario to collect the data from various nodes and integrate it to the other nodes in the network. For Simulation, VANET environment is created with Vehicles and RSU units, shortest path routing algorithm is implemented for data communication between RSU units. The hardware prototype is created with two vehicles and one RSU unit, the data is collected from both the devices and emergency messages are transmitted to other vehicles. The setup is able to collect the data when collision occurs and this is transmitted to RSU for data processing.
