Topics for student works
Modeling Dynamic Real-Time Ethernet Networks
- Communication links (flows) change at runtime, i.e, dynamically during operation
- When adding new flows, other flows may need to be migrated
- Flow migration must be done so that real-time capability is maintained at all times
Tasks
- Familiarization with the work "Dynamic Flow Migration for Delay Constrained Traffic in Software Defined Networks"
- Formulating problems with Python for Integer Linear Programming (ILP)
- Use of the ILP solver Gurobi to solve optimization problems
- Extension of the work "Dynamic Flow Migration for Delay Constrained Traffic in Software Defined Networks" with the help of a given ILP problem formulation
Helpful prerequisites
- Python knowledge
- Basic knowledge of networks (ISO/OSI)
- Basic knowledge about optimization problems
Type of student work
- Student or academic assistant
- Bachelor thesis
- Master thesis
Simulation/practical testing of a configuration framework for real-time capable TSN Ethernet switches
- Standardization process for real-time Ethernet: Time-Sensitive Networking (IEEE802.1Q, TSN)
- TSN enables hard real-time & simultaneous integration of non-real-time traffic
Tasks
- Get to know the simulator OMNeT ++
- Get to know TSN, esp. IEEE 802.1Qav (Credit-based Shaping, Forwarding and Queuing Enhancements for Time-Sensitive Streams)
- Implementation of a basic configuration framework in OMNeT ++ or in a real test bed
- Simulation or testing of the basic configuration of TSN switches
Helpful prerequisites
- C/C++ knowledge

Coordination and communication of autonomous underwater vehicles
Backgound
- Maintenance of the foundations of offshore wind turbines and clearance of unexplosed ordnance through autonomous underwater vehicles (AUVs)
- AUVs have to navigate cooperatively, have limited energy, and communicate opportunistically through acoustic modems
Tasks

- Conception of the cooperative navigation of several AUVs
- Modeling of energy consumption through activated sensors and movement
- Modeling of opportunistic communication through acoustic modes in realistic underwater environments
- Implementation of a aimulation model in OMNeT++
- Simulation in OMNeT++ and evaluation of simulation results
Helpful prerequisites
- C++ knowledge
- Basis knowledge of networks (ISO/OIS)
- Basic understanding of simulators
Type of student work
- Student or academic assistant
