The MTA-BME Information Systems Research Group started on July 1, 2012 as one of the subsidised research groups of the Hungarian Academy of Sciences at the Budapest University of Technology and Economics. The leader of the group is Miklós Telek.


Main research topics

Stochastic modelling
We research stochastic modelling techniques of network traffic and queues; development, analysis, optimization and dimensioning in the presence of various types of network traffic. We also research stochastic properties of the traffic. For the models proposed, we also implement efficient approximation methods. One of the main priorities throughout the research is scalability of the models.

Examination of communication strategies
We examine routing algorithms from a theoretical and practical perspective. We research the topology of the World Wide Web to introduce efficient routing algorithms. We also research other routing related problems such as efficient data structures and compression methods to be implemented in routers.

Quantum information and communication
We explore the potential of future quantum communication networks by examining reliable quantum communication over noisy quantum channels and calculating quantum capacity bounds. We also research quantum encryption systems and the information processing model of quantum gravity. We explore and analyse new types of quantum channels.


Some important results

In 2015, the prestigious Nature Communications published the paper Navigable Networks as Nash Equilibria of Navigation Games co-authored by Andras Gulyas, Attila Korosi and Gabor Retvari, members of the research group, and Jozsef Biro, a professor associated with the research group. The results had a considerable impact in both scientific circles and for general audiences.
