Handover mechanisms in VMC systems: Evaluating the reliability of V2X as an alternative to fiber networks in handover areas

Abstract

Despite advances in communication ways in autonomous driving, including Vehicle-to-Vehicle Communication (V2V), Vehicle-to-Everything Communication (V2X) and Vehicular Micro-clouds (VMC). In this paper, the potential of V2X as a substitution for the artificial connections (mainly optical-fiber cables) between base stations and edge servers are discussed. The quality and latency of communication in Handshake--referring to the scenario of cars moving from one stations operation scope to another ones, is mainly concerned, within the frame of VMC. Additionally, the communication performance, referring to latency performance and data rate performance, for both pure V2X and a combination of LTE and V2X are simulated and analyzed using a Python simulator. Finally, the test results showed that the performance of pure V2X Communication is always superior compared with any combination in every categories as the density of cars gradually increase, which confirms that replace physical inter-station-cables as V2X communication is serious possibility.
