Current Research Focus

The LEAD project "Dependable Things" sponsored by Graz University of Technology aims to devise methods and tools to predict, guarantee, and ultimately raise the level of dependability of the IoT.
Within this project, I am involved in the "dependable wireless communication and localization" sub-project that aims to automatically adapt system parameters using models of the transceiver hardware and the environment.

DependableThings: Dependable Internet of Things in Adverse Environments

Time window: January 2016 - December 2018

Type: LEAD Project - TU Graz

By 2020, the Internet of Things (IoT) will consist of 50 billion resource-constrained "Smart Things" that will provide critical every-day services in applications as diverse as Smart Cities, Smart Production, or Connected Cars. These applications require a dependable IoT despite hostile environments and deliberate attacks, where dependability summarizes aspects such as reliability, safety and security that enable users to put trust into the IoT. Today’s approaches to construct an IoT do not guarantee dependability. The research center "Dependable Internet of Things" brings together the best researchers from the departments of Computer Science & Biomedical Engineering and Electrical & Information Engineering at TU Graz in order to provide the scientific foundations for an IoT that works dependably and that is resilient against failures and attacks. Besides carrying out cutting-edge basic research aiming to offer methods and tools to predict, guarantee, and ultimately raise the level of dependability of the IoT, the center aims to transfer the research results into real-world applications together with local and international industry partners.
Within this project, I am involved in the "dependable wireless communication and localization" sub-project that aims to automatically adapt system parameters using models of the transceiver hardware and the environment.




RELYonIT: Research by Experimentation for Dependability on the Internet of Things

Time window: November 2012 - January 2015

Type: EU-funded (STREP)

By embracing vast quantities of wireless sensors and actuators, the Internet of Things (IoT) is deemed to enable applications of utmost societal value including smart cities, smart grids, and smart healthcare. Most of these applications pose strict dependability requirements: sensor data and actuation commands must be delivered reliably and timely while batteries powering devices must last for a given time in the order of years. Failure to meet these requirements may result in risks for humans and infrastructures, insufficient user satisfaction, and high costs.
However, existing IoT solutions do not provide dependable performance. A major reason for this is that embedded wireless sensors and actuators are deeply affected by their often hostile environment. For example, temperature and humidity variations can affect the battery capacity and electronics, whereas radio interference from other wireless equipment and electrical appliances may impair communication.
By analyzing and modeling several environmental properties, the goal of RELYonIT is to provide a systematic framework and toolchain to enable dependable IoT applications.
Outcomes of my involvment within RELYonIT are, among others, the JAG protocol to guarantee reliable and predictable wireless agreement under external radio interference.





CONET: The Cooperating Objects Network of Excellence

Time window: June 2009 - October 2012

Type: EU-funded

The EU-funded CONET Consortium is working on building a strong community in the area of Cooperating Objects, and encompasses research, public sector, and industry partners from the areas of embedded systems, pervasive computing, and wireless sensor networks.
Within CONET, I work in the Resource Management and Adaptation (RMA) cluster together with other five members. Key objective of the RMA cluster is the development of mechanisms for reliable assessment of the current RF interference situation as a basis for dynamic resource adaptation that will provide better end-to-end system performance and quality of service. The adaptation process requires a cross-layer coordination of several protocol components like medium access control (MAC), packet scheduling, and others while satisfying external constraints like technology, fairness, transmission quality, and legal constraints.
My research focus was on improving the robustness of wireless sensor networks against radio interference, and outcomes of this work are, among others, the JamLab tool for interference testing and the Triangle Metric for a fast link quality estimation for mobile wireless sensor networks.





Cluster of Excellence "Inflammation at Interfaces"

Time window: June 2009 - October 2012

Type: DFG-funded

The DFG Excellence Cluster on Inflammation at Interfaces involves more than 200 researchers in genetics, biology, medicine and engineering who are investigating causes and treatment of inflammatory diseases by which millions of patients are affected in the developed world.
Within this context, I investigate (i) the use wireless sensor networks as a tool for monitoring patients, and (ii) how to apply bio-inspired self-organization techniques to make sensor networks more robust. In particular, I investigate the use of body sensor networks for fine-grained and long-term monitoring of body parameters in collaboration with the Institute for Neuroendocrinology and the Institute of Psychiatry at the University of Lübeck.
Outcomes of this work are, among others, a body sensor network for measuring temperature accurately and a body sensor to measure the core body temperature of Marathon runners deployed during the 5th Lübeck Marathon.





GINSENG: Performance Control in Wireless Sensor Networks

Time window: September 2008 - May 2009

Type: EU-funded

The EU-funded GINSENG project has carried out successful research on performance control in wireless sensor networks for industrial monitoring and control applications.
Within this context, I investigated the impact of temperature and weather conditions on outdoor-deployed wireless sensor networks, highlighting the importance of testing communications during the hottest times of the year. Outcomes of this work are the analysis of the impact of temperature and weather on outdoor industrial wireless sensor networks.
