Coordination by Means of Resource Management
Due to its shared nature, the wireless channel is used by various applications of different criticalities and with different requirements and constraints. This makes timing guarantees impractical, as long as no coordination is used. A centralized application-centric Resource Management (RM) approach that is based on Software Defined Networking (SDN) principles (communication divided into control and data plane) has been developed to address the coordination of various wireless applications.

Application-centric Resource Management
A centralized application-centric Resource Management (RM) approach that is based on Software Defined Networking (SDN) principles (communication divided into control and data plane) has been proposed to address the coordination of various wireless applications. Specifically, a hierarchical architecture is employed that allows for coordination across network segments.

Shared Slack Budgeting for Ultra Reliable Hard Real-Time Streaming
Applications with varying requirements and constraints are envisioned to share a wireless channel in order to enable improved cooperative behavior in autonomous systems. Most challenging in that regard are application exchanging large objects such as sensor data. So far the exchange of such data has not been addressed by wireless (V2X) standards. While W2RP and its extensions offer reliability mechanisms for such data exchange, so far only single applications are considered.

Safe and Synchronized Reconfiguration Protocol
While the previous work on application-centric resource management addressed the coordination of multiple applications and network segments, it so far lacked detailed descriptions on how safety can actually be achieved given such a resource management approach. The reconfiguration protocol proposed here addresses these concerns, deriving constraints and requirements from a widely applicable system model that includes vehicle dynamics
