With research trendingtowards increasing amounts of Vehicle-to-Everything (V2X) applications that use a shared wireless medium for data exchange, the coordination of those applications gains more and more importance. Application-centric Resource Management (RM) is a promising candidate for that coordination. It allows to address both application constraints as well as network properties in order to guarantee adherence to real-time and safety constraints of critical applications, such as cooperative perception based on large data object streaming. These applications require the reliable and fast exchange of large data objects. We use earlier work on error correcting real-time protocols with a safe control protocol for application-aware dynamic network (re-)configuration. The RM mechanisms were evaluated using a physical wireless prototype that used commodity of the shelf hardware that resembles an automated valet parking use case. The RM proved highly effective in preventing constraint violations. Meanwhile, it did so in a predictable and synchronized manner even if the wireless channel is subject to non-negligible error rates. |
