How the Internet of Vehicles advances transport telematics

IoV provides opportunities to increase road safety, reduce fuel consumption as well as pollution, and cut various business-related costs. In addition, each vehicle on the road could potentially serve as an information hub or edge server for people and various IoT devices on the road.

Internet of Vehicles (IoV) is a result of increased smart vehicle connectivity opportunities to the Internet of Things (IoT). IoV seems to be a promising paradigm, already shaping the future of vehicular connectivity while boosting automotive markets and pushing forward the 4G/5G/6G related innovations.

The IoT devices could be deployed on the roads and integrated into various intelligent traffic information systems via 5G networks. An example of such NFV-based IoV is shown in a figure above [Yulei Wu et al., 2019].

Utilizing 5G and possibly 6G connectivity benefits, IoV expected to enable high speed, low latency time, and intelligent scheduling in a wide range of applications. IoV includes a large number of vehicles, as well as things and networks that have been equipped with many network function virtualization enabled devices.

Seven-layered model architecture for IoV

Let's consider an IoV environment that was proposed by [Contreras-Castillo, J. et al, 2017] and is shown on a figure below.

User Vehicle Interface Layer provides direct interaction with the driver through a management interface, reducing the driver’s distractions. Data Acquisition Layer collects data from various sources located on the roads. Data Filtering and Preprocessing Layer analyzes the collected information to avoid the transmission of irrelevant information and reduce network traffic.

Communication Layer selects the best network to send the information by using several selection parameters such as congestion and QoS level in the different available networks.

This layer followed by the Control and Management Layer, responsible for managing different network service providers that are within the IoV environment. In this layer, different policies and functions are applied to better manage the information received.

Processing Layer on its turn processes large amounts of information using various types of cloud computing infrastructures locally and remotely. The results of the processed information can be used by massive data services providers to further improve the service or to develop new applications. The security layer is a transversal layer that has direct communication with the rest of the layers.

IoМ has the potential to form a cohort of service providers that will offer new services such as real-time traffic information, parking spot locations, location-based services, that would be highly valuable both for vehicle owners and telematics-related businesses.

IoV provides plenty of benefits including dynamic information services, smart vehicle control, applications aimed at insurance rates reduction, and increased efficiency obtained via reduced traffic.
