Research Interest

My research topic is centered around distributed adaptive systems. Starting with the investigation of decentralized monitoring mechanisms in distributed dynamic systems such as peer-to-peer systems we developed a benchmarking methodology to consistently compare mechanisms in such environments. Focusing my research on adaptivity I widened my scope and started my work on generic dynamic adaptive systems, e.g., smartphones or sensor nodes, which have continuously adapt to a certain context. Leveraging model based methodologies from the domain of dynamic software product lines I’m currently investigating how to reconfigure dynamic adaptive systems during run-time.



As of January 1st, 2013, the German Research Foundation (DFG) has approved the collaborative research centre (CRC) 1053 “MAKI - Multi-Mechanism-Adaptation for the Future Internet”. Initially, the CRC will be funded with 8 Million Euros over the next four years.

MAKI creates an innovative premise for communication systems in the future. Its aim is to be more adaptive to changes, particularly during ongoing operations. For instance, this could facilitate the ability to stream a video on a smartphone in high-quality and without interruptions in spite of busy or overloaded mobile networks. Users could rely on a steady and reliable reception even when attending festivals or crowded sporting events.

The Internet has vastly evolved into an integral part of our everyday life. Consequently, the necessary communication mechanisms and equipment are changing on a constant basis. The individual solutions related to this rapid evolution are widely considered as problematic. Currently, as many as three standards exist for Bluetooth, Wi-Fi, and now LTE alone. The result: a multitude of services, often based on different technologies. MAKI considers this diversity as an opportunity by optimizing the individual attributes of particular mechanisms to meet the desired quality objectives.

MAKI is the first CRC of its kind in the field of information technology and computer science at TU Darmstadt. In CRC 1053, engineers and computer scientists, together with scientists for urban- and spatial sociology, are concerned with the issue of “Mechanisms for the Future Internet”. A total of 12 departments of the TU Darmstadt work in collaboration. These include six departments fromthe area of computer science, five from the area of electrical engineering and information technology and one from the area of sociology. In addition, a research group from the University of Illinois at Urbana-Champaign as well as a department of the RWTH Aachen are participating in the CRC. Their collaboration ensures extensive and comprehensive expertise in the research of communication mechanisms. Chairman and coordinator of the CRC 1053 is Prof. Dr.-Ing. Ralf Steinmetz, head of the Multimedia Communications Lab at TU Darmstadt.

QuaP2P (Finished December 2012):

The objective of the QuaP2P research project is to enhance the quality of peer-to-peer (P2P) systems by systematically researching suitable mechanisms. Specific quality features will be applied to assess the quality of the P2P systems. This will be achieved by using and comparing it to centralized procedures as the respective reference points.

The current second phase of QuaP2P focuses on the methodology of researching multilateral interdependencies between various quality aspects as well as on the characterization of these interdependencies. Therefore, a benchmark methodology for P2P systems will be developed, allowing for the investigation of the quality aspects of existing P2P systems.

The results from this research project should also provide (1) the answer to the question in which areas P2P systems are superior to centrally controlled systems, (2) what will be the consequences for the further systematic development and (3) what other (maybe until now even somewhat ignored) applications may be obtained from the P2P paradigm.

Within the QuaP2P project I’m also focusing my research on a model based MAPE loop (Monitor - Analyze - Plan - Execute). Goal of my research is to enable context awareness in distributed decentralized dynamic adaptive systems like smartphones or sensor nodes. To approach this challenge we make use of dynamic software product lines, to derive a plan according to a certain context. The plan is then used to adapt the device during run-time in the execution phase.

My research in the MAKI project is focused on model based adaptation of resource constraint mobile devices, such as smartphones, tablets, and notebooks. In this regard, I investigate variability models, weighted and probabilistic transition systems, and constraint reasoner to derive a suitable device configuration for an continuously changing contextual environment. 


The MOFLON tool set is designed to perform a wide range of tasks in the fields of model analysis, model transformation, and model integration for standard modeling languages like UML or domain-specific modeling languages. It is possible to create a new domain-specific engineering language (DSL) or model-driven software engineering solution (MDA/MDD). 

In MOFLON I am involved in the integration of OCL, the integration into eclipse via plugin and the quality assurance of the project.
