Future Transportation
Soon every Vehicle will be equipped with OBU module which consists of these main parts:
Management and Control
Communication & Networking
• Management and Control
System Architecture for AV(Autonomous Vehicles) or ADAS
• Communication & Networking
VANETs are an emerging sub-class of mobile ad-hoc networks capable of spontaneous creation of a network of mobile devices/vehicles. VANETs can be used for vehicleto-vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication. The main purpose of such technology is to generate security on the roads; for example, during hazardous conditions such as accidents and traffic jam the vehicles can communicate with each other and the network to share vital information. VANETs formation, services and use cases are based on ITS stack.
And Technology approved for access are:
The main components of whole Vehicle Networks technology are:
1. On-board unit (OBU): It is a GPS-based tracking device embedded in every vehicle to communicate with each other and with roadside unit (RSU). To retrieve the vital information, the OBU is equipped with many electronic components such as resource command processor (RCP), sensor devices and user interfaces. Its main goal is to communicate between different RSUs and OBUs via a wireless link.
2. Roadside Unit (RSU): RSU is a computing unit fixed at specific location on roads, parking areas and intersections. Its main goal is to provide connectivity between autonomous vehicle and the infrastructure and also assists in vehicle localization. It can also be used to connect vehicle with other RSUs using different network topologies. They have also been powered using ambient energy sources such as solar power.
3. Trusted Authority (TA): It is an authority which manages the entire process for VANETs, so that only valid RSUs and vehicle OBUs can register and communicate. It provides security by verifying the OBU ID and authenticates the vehicle. It also detects malicious messages or suspicious behavior.
