Dr. Alexander Willner is the head of the Industrial Internet of Things (IIoT) Center  at the Fraunhofer Institute for Open Communication Systems (FOKUS)  and the head of the IIoT research group  at the chair of Next Generation Networks (AV)  at the Technical University Berlin (TUB). In joint collaboration with the Berlin Center of Digital Transformation (LZDV)  he is working with his groups in applying standard-based Internet of Things (IoT) technologies to industrial domains. With a focus on moving towards the realization of interoperable communication within the Industry 4.0, the most important research areas include industrial real-time networks (TSN), middleware systems (OPC UA), distributed AI (Digital Twins) and distributed Cloud Computing (Edge Computing) including management and orchestration.
Prior research positions include the University Bonn, he holds an M.Sc. and a Ph.D. (Dr.-Ing.) in computer science from the University Göttingen and the Technical University Berlin respectively. His research interests are on distributed information systems, linked data, communication middleware and service-oriented architectures. He is active in relevant standardization activities and alliances and gives a corresponding lecture at the Technical University Berlin; and in the past at the Humboldt University of Berlin as well.
At various occasions Dr. Willner also acts as ambassador for the science capital Berlin .

|Abstract||The Internet is broken and there are several approaches to fix it. In order to validate the different attempts, they need to be evaluated within large-scale environments involving numerous heterogeneous resources. As a result, several testbeds have been established along with a number of competitive mechanisms to federate them. Since most of these protocols try to address similar issues, combining and unifying them is subject of current research. This leads to a complex environment for testbed owners and developers. Furthermore, it is foreseeable that even more federation approaches in different application domains will emerge in the future. Therefore, we propose an extensible architecture that allows to be federation protocol agnostic. The fundamental idea is to allow interoperability on the level of a semantic information model and to separate delivery mechanism specific implementations from a common core. The requirements for such an architecture have been extracted from latest European Future Internet research projects and its practicability is being evaluated by an initial implementation.|
