PhD Position / Research Assistent (f/m) – Intelligent Wireless Networks

Innovations for the digital society of the future are the focus of research and development work at the Fraunhofer Heinrich Hertz Institute HHI. In this area, Fraunhofer HHI is a world leader in the development of mobile and optical communication networks and systems, fiber optical sensor systems as well as the processing and coding of video signals.

The Wireless Communication and Networks (WN) department performs research within the broad area of wireless communication systems and networks ranging from information theory to the implementation of demonstrators and tests in the field. Special emphasis is put on network architectures, control and data plane design, network measurement and traffic analysis, design of virtualized networks, self-organisation and self- optimisation, heterogeneous access management, cooperative systems, distributed wireless networks including massive wireless sensor networks, resilient networks, cross-layer optimisation, cognitive radio, multi-antenna systems, and AI/ML algorithms for network optimization.

The PhD position is connected with a project called “IC4F - Industrial Communication for Factories”. The flagship project IC4F focuses on a technology toolkit for a trustworthy industrial communication and computing infrastructure for the digitalization of the manufacturing industry.
Research topics include:

  • Intelligent detection of faults and anomalies in wireless access networks including 5G campus networks
  • Research in the scope of Software-Defined Networking (SDN) and Network Function Virtualization (NFV) includes
- Data and control plane design for enterprise, industrial, 5G campus networks  and beyond leveraging Programming Protocol-Independent Packet Processors (P4)
- Design and realization of Network Packet Broker (NPB) (on any OSI layer), In-band Network Telemetry (INT) approaches, as well as design and placement of data plane network functions
- Design of virtual network functions specifically for wireless networks including mobile networks
  • In-Network Computing (INC) for wireless, enterprise, and data center networks; Design of joint hardware-software co-designed systems.
  • AI-based network optimization leveraging NPB, INT and INC approaches (Traffic prediction, resource reallocation, self-healing)
  • Design of unified analytics engines for ML-based anomaly detection
  • Resilient network design considering data centers, storage, computation, radio and core network resources
  • Cross-layer design optimizations for dense wireless access, multi-hop relay, and mesh networks
  • Development of secure communication and computing systems with real-time capabilities

What we expect from you

  • University studies completed with very good academic achievements
  • Very good oral and written proficiency in English.
  • Very good proficiency in software development.
  • Very good knowledge of the GNU / Linux system architecture
  • Knowledge in the fields of machine learning, artificial intelligence and big data analytics
