Stephan Reiff-Marganiec: Research

Research Interests

My research considers runtime adaptation of complex networked software systems and approaches and software architectures for modelling, managing (using semantic data integration) and efficiently processing data for data analytics. I have a particular interest in architectures, data management and analytics that can be distributed and allow action close to the source of the data as is needed for smart environments.

I have pursued three related research strands which are now cumulating in solutions for problems in the context of IoT and Smart World solutions.

(1) I have conducted research in various systems that adapt at runtime, ranging from feature interactions in telecommunications, adapting workflows [9] and selecting most appropriate software services [10] and recently cloud and IoT resources [1][5]. Solutions typically evaluating multi criteria decision problems to dynamically decide which of many possible components providing a certain functionality are best for a given situation have been created.

(2) A second strand focuses on data modelling and management; this uses technologies ranging from UML modelling to semantic web solutions to complex event processing (CEP) to capture data in the best possible way and to allow reasoning about the data [4][6][8] – some of my current work is considering the application of AI techniques to such data.

(3) A third, and partly more recent, strand of work is focussing on fast data processing [6]. The achievements in this strand are a platform providing a combined pull-push model for collecting data and accessing information with near zero delay. This platform has been formally modelled using ITL (interval temporal logic) and hence can be formally reasoned about.

Bringing these strands together, I am currently investigating data processing platforms that optimise where data is processed (in device, fog/edge or cloud – or a combination thereof) [3]. This optimisation is driven by numerous factors such as the availability of the data to make decisions, the processing need and device capabilities as well as the speed and precision needed for deriving answers. Initial results exist for providing autonomy to IoT devices, allowing them to work in a peer to peer fashion and processing data locally [7] as well as a hybrid approach for processing data in the cloud and edge/ fog [3]. We have also developed a simulator (FABIoT) to experiment with various data processing setups [2].

Activities

Past Research Positions

  • Research Assistant on the HFIG project (1998-2001).
    HFIG was addressing the problems of detecting and resolving feature interactions between telecommunications services. In particular the development of a hybrid (i.e. off-line and on-line) and adaptive approach to detecting and resolving feature interactions was investigated. The work on the project ranged from formal modelling and reasoning to the development of software for managing interactions between new and legacy services. The research was conducted in partnership with Citel Technologies Ltd and Mitel Telecomms.
  • Research Fellow on the ACCENT project (2001-2003).
    ACCENT investigates the use of policies in a call control context. Policies are used in systems managament for example for access control, but they have not been used much for call control. The ACCENT project is in colaboration with Mitel Telecoms Ltd and the Universities of Ottawa and Waterloo in Canada. Details of the collaborators can be found on the COMPASS website.
