Research Statement

My research efforts focus on wireless mesh networks and WLANs, concentrating on the three lowest layers of the network stack. I am interested in design, modeling, measurements and implementations, especially for wireless crosslayer mechanisms. My work is mainly on interference mitigation mechanisms and spans two wireless technologies, (a) the IEEE 802.11 and (b) impulse-based UWB. On wireless LANs and mesh networks, I am interested in measurementbased methodologies, as well as kernel-level implementations for performance improvement algorithms [1], [2]. On UWB my research includes multi-band MAC protocols [3], [4] that manage to utilize efficiently the available spectrum and alleviate interference effects. • Publications: Currently I have 12 publications in high-class journals and conferences. In particular, I have 2 published journal papers and 10 conference/workshop papers. My journal papers have been published in IEEE Transactions on Mobile computing and in Wiley Journal of Wireless communications and Mobile computing. My conference papers have been published in INFOCOM, MOBICOM, SECON, PAM, ICCCN and other popular international conferences and workshops. Moreover, I currently have 5 pending paper submissions, from which 2 have been submitted to journals and 3 to conferences. • Measurement, Simulation and Analytical Tools: I have designed, deployed and maintained wireless testbeds for 802.11 networks, as well as simulators and analytical frameworks for impulse-based UWB. In particular: – I have designed, constructed, deployed and administered two large-scale wireless testbeds [5], [6], [1] at th
