I am member of the NITlab group, whose Founding Director is Prof. Leandros Tassiulas and Executive Director is Prof. Thanasis Korakis.
My research interests include the design and implementation of enhanced algorithms on wireless and software defined (SDN) networks, as well as the experimentation on these algorithms performance using testbed platforms and open source frameworks.edit

We demonstrate a queue-aware algorithm studied in a diamond network topol-ogy. This algorithm's decisions are obtained from an analytical optimization framework relying on our technical work [4] and we devise an implementation part by modifying the features of ath9k driver [3] and click modular router [5]. Performance evaluation is conducted through experimentation on the NITOS Wireless Testbed and it reveals a significant rise in total throughput considering a particular networking scenario while also it maintains stabil-ity of backlog queues when schedules indicated by Lyapunov-based technique as throughput optimal are selected.

Abstract. This demo presents a novel routing and scheduling scheme, named Enhanced-Backpressure over WiFi (EBoW), that obviously outperforms the dominant approach of a shortest-path routing (SRCR) combined with the classic CSMA/CA scheduling policy of 802.11 networks. The new scheme combines aspects of load-balancing and shortest-path routing and enhances the CSMA/CA scheduling, maximizing the throughput performance, while keeping low end-to-end delay. We perform a comparative demonstration of video ...
