A Simulation Framework for Validating Cellular V2X Scenarios

With the continuous progress of radio technology it is becoming evident that the cellular network will support advanced cellular Vehicle-to-Everything (C-V2X) services, which require connectivity that can provide low latency, high data throughput, high reliability and broad coverage. Before these services are fully deployed in reality, and due to ethical and safety reasons, we turn to simulation to study the support of the cellular network for such services. Therefore, in this paper, we propose a realistic simulation framework for urban C-V2X usecases. The framework consists of an urban mobility simulator, which can accurately model urban traffic, and a network simulator capable for simulating at least the LTE radio equipment and the network protocol stacks in the urban area where the C-V2X service will be offered. We validate the simulation framework by performing a feasibility assessment of a vehicle teleoperation usecase in one urban area of the city of Stockholm.
