Curriculum Vitae

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 Mobile Network Operators provide wireless communication services to their customers using their own network infrastructures. For providers, in particular in low-income countries, access to latest network functions to offer 4G/5G services can be a large burden as this is directly impacted by financial restrictions of operators. Although some network sharing solutions between operators to reduce the total cost of ownership exist in standards and literature, none address specific requirements of the operating environment of low income countries. In our approach, we are exploiting the raising interest in the cloudification of the related infrastructure, namely Network Function Virtualization (NFV) over Software Defined Networks (SDN), to allow each operator in these countries to offer specific network functions as a service in a federation in order to share them and to increase their revenue.Initial results are presented based on the development of a commercial toolkit (OpenSDNCore) and a federated testbed research project (TRESCIMO). As a result, we define the notion of a Mobile Federated Network Operator (MFNO) and provide an analysis of the underlying requirements for such a use case and potential approaches to address them.
