Scientific Methods

The following types of engineering/scientific methods are recommended for the proposed topics, but are also matter of discussion and agreement with the student:

Simulation: simulation of the technology in a simulator as mutually agreed by the student and TTTech

Prototyping: prototyping of the technology, can be hardware, software or both

Demo-Kit: the work will largely be based on TTTech’s available components, improve and configure these components towards a demonstrator

If you are interested in contributing to cutting-edge technology development, TTTech offers you a wide range of research topics in various fields:

Communication Networks With Real-Time and Safety-Criticality Aspects

Time-Triggered Ethernet at 10Gbit/sec

Content: Today, Time-Triggered Ethernet (SAE AS6802) components support 100Mbit/sec and 1Gbit/sec data rates. The aim of this thesis is to evaluate the possibilities to improve the data rate of Time-Triggered Ethernet to 10Gbit/sec and give an outlook on the possibilities for even higher data rates.

Engineering/Scientific Method: Prototyping

Comparison of Modeling Techniques for Time-Triggered Ethernet Networks With SysML/AADL/OPNET/Simics/etc.

Content: Simulation can be used to evaluate the suitability of Time-Triggered Ethernet for given use cases. The topic of this thesis is to evaluate different simulation options. Some simulation modules of the Time-Triggered Ethernet technology already exist today and can be used as starting point of the thesis.

Virtualization

Evaluation of Different Network Traffic Shaping Mechanisms in Deterministic Ethernet Solutions for the Automotive Industry

Content: Ethernet is on its way to become the backbone of in-vehicle communication. Automotive Ethernet will be based on a collection of standards, e.g., IEEE 802.1 (AVB/TSN, TSN++), IEEE 802.3, and SAE AS6802. The objective of this thesis is to evaluate different network shaping concepts (e.g., credit-based shaping, urgency-based shaping, time-based shaping, preemption) in isolation as well as in combination with each other.

Evaluation Platform for Automotive Ethernet

Content: Ethernet is becoming the next major standard for in-vehicle communication. TTTech has developed and continues to develop standard products for the automotive communication market. This thesis will develop an evaluation platform that incorporates these standard products and demonstrates Automotive Ethernet in selected use cases from the automotive industry.

Deterministic Wireless Communication

Content: Wireless communication is an attractive alternative to wired communication because of various reasons, e.g., flexibility and mobility. However, wireless links are inherently magnitudes of orders less reliable than wired connections. Thus, the aim of this thesis is to investigate novel approaches to improve various real-time and dependability properties of wireless communication.

Dynamic Real-Time Scheduling in Cyber-Physical Systems With Hierarchical Structures

Content: Modern cyber-physical systems implement a hierarchical structure of dependencies such that various scheduling entities need to be aligned to each other. For example, a typical structure will encompass task scheduling, virtual machine scheduling, and communication scheduling. The objective of this thesis is to investigate dynamic real-time scheduling solutions and find optimal scheduling strategies in such a system’s context.

RT-Wrappers

Content: Re-use of existing SW code becomes a more and more relevant topic also for cyber-physical systems. Such SW that needs to be adapted could be either legacy code or code developed for other industries, e.g., the IT. The objective of this thesis is to develop a strategy and a prototype to seamlessly integrate existing SW code into a cyber-physical systems context.

Real-Time Operating Systems for Next Generation Cyber-Physical Systems

Content: TTTech develops HW/SW platforms for cyber-physical systems, such as for example the aerospace, space, automotive, off-highway or industrial automation markets. The selection of a specific Real-Time Operating System and adapting the RTOS for use in the platform requires significant engineering skill. The objective of this thesis is, therefore, to evaluate various RTOS for TTTech’s platforms.

Configuration and Management

Static Scheduling for Time-Triggered Systems

Content: Time-triggered systems make use of a static schedule that defines the access patterns of processes to shared communication/computation resources. The production of such schedules is a non-trivial activity and an active field of research. The objective of this thesis is in the area of evaluation of new scheduling paradigms and, potentially, in the development of novel scheduling approaches.

Engineering/Scientific Method: Prototyping

Integrated Dynamic and Static Real-Time Scheduling

Content: More and more cyber-physical systems integrate static and dynamic scheduling approaches. For example, Automotive Ethernet provides both, dynamic and unsynchronized traffic to be communicated over the same physical network as time-triggered traffic. Similarly, combined scheduling problems arise in processor scheduling. The objective of this thesis is to analyze existing integrated scheduling paradigms and, potentially, to further develop the scientific field of scheduling in this direction.
