Quality-of-Service and Connected Mobility
Quality-of-Service and Connected Mobility
Quality-of-Service (QoS) parameters like goodput, packet loss, latency, and jitter are not only responsible for the quality of experience of communication systems. In many fields of application, fulfilling the QoS requirements is also essential for a safe and reliable performance of the offered services. Industrial communication and communication between electronic control units in vehicles are examples for critical applications. In both systems, messages need to arrive within given time bounds so that the system can react to events in the required time frame.
In our Quality-of-Service and Connected Mobility research group we evaluate relevant QoS metrics of communication systems. For this purpose, we apply measurements, modeling, simulation, mathematical analysis, Network Calculus, and optimization. We also design communication systems and protocols that can fulfill given QoS parameters.
Current fields of application are communication systems in rail vehicles, smart grids, time synchronization for the development of vehicular control units, modern Ethernet standards (TSN), and satellite-based Internet communication.
In our group we are also particularly concerned with communication technologies relevant for vehicular networking (i.e., IEEE WiFi, 5G/6G Vehicle-to-Everything, V2X). The simulation environment VEINS, that combines road traffic simulation with network simulation, has been developed initially at this lab and is extended in our projects. There is a long-standing cooperation with the automotive industry, in particular through the joint PhD-program INI.FAU in cooperation with the Audi AG (http://www.ini.fau.de) and with other automotive companies.
