Research

The institute of Telematics explores different aspects of distributed systems. One focal point is the research into methods to guarantee fault tolerance in distributed systems on the basis of self stabilizing algorithms. In this line of research we devise distributed self stabilizing algorithms for fundamental problems, compute their complexity and analyze their fault containment behavior. The field of wireless sensor networks is used to verify our methods. This requires designing the algorithms in a way that they can operate under the given boundary conditions. A second focus is on energy-aware systems. In particular we investigate energy budgeted sensor networks based on renewable energy sources. The nodes of such a network have an energy budget that is refilled from a solar cell. The challenge is to devise a plan to perform a given set of tasks over a given time. The generation of the plan must take into account the anticipated inflow of energy and the energy usage of the hardware.

These theoretical works are complemented by industry related projects. A transfer of knowledge into applications takes place in these projects. Currently these projects are related to aeronautical research. Alongside these efforts we also investigate distributed systems to explore new forms of collaboration in higher education. A project is dedicated to the development of a web based system implementing ePortfolios.

Self-Stabilizing Systems

A distributed system is self-stabilizing, if it returns to a legitimate state regardless of the initial state and remains in a legitimate state until a fault occurs. Self-stabilization is a non-masking approach to fault-tolerance. In this institute we analyse self-stabilizing algorithms with respect to their efficiency as well as behaviour in case of a fault and create tools that support the development of such algorithms. details

Sensor Networks

Embedded networked sensing systems provide solutions to many scientific and social applications. Sensor networks are massively distributed systems of heterogeneous sensor nodes, some of them are connected by a wireless network. Limited energy, memory, and processing resources demand for solutions radically different from approaches in traditional distributed systems. In our Institute we mainly focus on investigations for applying middleware technologies for wireless sensor networks. details

Programming Techniques for Multi-Core Architectures

The move to multi-core architectures in the end user domain currently happening forces the software industry to move to parallel programming techniques. Parallelisation is known to be a complex task and still challenging for experienced programmers as well. In the area programming techniques for multi-core architectures we are looking for techniques to ease parallel programming. details
