Network Slicing solutions for Internet of Vehicles (IoV) Networks: A Review

The implementation of network slicing services, designed to fulfill the diverse requirements of each Vehicle-to-Everything (V2X) use case, has significantly facilitated the expansion of the Internet of Vehicles (IoV). Three critical communication needs for the V2X ecosystem are ensured by network slicing: ultra-low latency and high reliability, enhanced mobile broadband, and massive machine-type communication (mMTC) support. In addition, network scalability, high mobility, and large density are taken into account. It is noteworthy that the utilization of network slicing technology has evolved beyond its fundamental objectives. In this context, the application of network cutting technology extends its objectives to encompass aspects beyond the essential requirements. This review aims to scrutinize and categorize scientific research endeavors within this domain, according to the specific objectives underlying the adoption of network slicing technology in the IoV ecosystem.
