Framework conditions for the implementation of backend-based functions in the context of Connected Vehicles: Sensitivity analysis of Maschine-2-Maschine protocols concerning the robustness of backend-based functions

摘要

In the scope of this contribution, the applicability of cloud systems is examined regarding the future implementation of backend-based vehicle functions. Prospectively, backend-based functions will be integrated as vehicle overlapping tasks with access to embedded vehicle controls. Referred to the typical three-layer architecture for the Internet of Vehicles (IoV) a high-level architecture for the implementation of backend-based functions is given. The potentials of such backend-based function can only be fully utilized if incoming data in the backend is processed immediately and resulting information are transmitted to the vehicle. As a result, backend-based function are exemplary considered as closed control circuits in this contribution. On the basis of Maschine-2-Maschine (M2M)-protocol analysis and a test framework, boundary conditions are derived for such functions. Analysis of the most relevant influencing factors are given. Results show that the end-2-end latency is one of the most important factors. This also makes the chosen message very important. This factor will improve due to developments regarding mobile communication standards, but still have a relevant impact on backend-based functions. This relevancy is outlined in this contribution as well.
