Research Projects

Currently pursuing the following research directions:

  • Caching techniques for (i) future Internet, (ii) future wireless communication systems, (iii) cloud storage systems

  • Network optimization algorithms for Software Defined Networks

  • Network orchestration for E2E latency guarantees

Past Projects

  • Conect (ICT - STREP - 11’-14’): proposes a holistic network design approach that drastically enhances performance in wireless networks by unlocking the hidden potential of the broadcast wireless medium. Information Theory, Communication Theory, and Protocol Design are merged to provide the foundations of provably optimal cooperative information forwarding strategies, from multi-signal fusion to packet relay and node reciprocation. A concrete experimentation plan validates the design choices and at the same time provides real-world feedback for fine-tuning of the architecture. It is based on the OPENAIRINTERFACE testbed for flexible radio network design and the NITOS testbed for cooperative wireless access and transport.

  • PURSUIT (FIRE - STREP - 10’-13’): PURSUIT revolved around the idea of routing based on content following the publish-subscribe paradigm for intradomain routing. With clear advantages in terms of efficiency and privacy, PURSUIT is a bet on how the Internet can be reshaped in order to remain sustainable and profitable. CERTH-ITI worked on caching and wireless as well as provided support in system development of the blackadder prototype. Received FIA AWARD

  • EnergyOPAL (Mini-project of Euro-NF): Brainstorming and exchange of ideas among four groups focused on energy efficient techniques for communications, i.e. CERTH-ITI Volos (leader), VTT Oulu, INRIA Sophia-Antipolis and Fraunchofer - HHI Berlin. A report of the project can be found here.

  • OPNEX (IST - STREP - 08’-11’): OPNEX delivered a queue-based approach to optimally controlling wireless communications networks. Implementation and system development bridged the gap between the theory of stochastic networks and actual network devices and pushed forward the standardization of such techniques. OPNEX produced a wealth of techniques, algorithms and experiments as well as wireless testbeds available for experimentation, see NITOS and DES testbeds.

  • N-Crave (IST - STREP - 08’-11’): N-Crave investigated the application of network coding to wireless volatile environment. CERTH-ITI contributed the NCRAWL framework for wireless network coding. The project contributed in theoretical advances of network coding and its applications and identified potential commercial applications that can benefit from network coding.

  • NetRefound (IST - FET - 07’-10’): NetRefound studied the foundations of networking, investigating limits of communication and developing techniques for approaching these limits. The capacity of wireless network was studied using percolation and other techniques borrowed from physics. A part of work was dedicated to autonomous systems and peer to peer networks.

Postdoctoral fellowship

  • WiNC was a personal grant that supported my research in the years 2012-2014. It was funded by Greek Secretariat for Research and Technology (“Supporting Postdoctorals”). WiNC focused on network coding for wireless and bridges the gap between practice and theory by studying dynamic and distributed control techniques for joint scheduling and coding.
