Adjunct Assistant Professor, CONNECT

Biography

I am an EDGE MSCA Research Fellow at CONNECT in Trinity College Dublin (TCD). I received the M.Sc. degree in wireless communications from the University of Southampton, Southampton, U.K., in 2010 with First Class and Distinction, and the Ph.D. degree in electrical engineering from the University of Calgary, Calgary, Canada, in 2015.

From July 2015 to May 2016, I worked as a Postdoctoral Research Fellow at the Ultra-Maritime Digital Communication Centre (UMDCC), Dalhousie University, Halifax, Canada. In 2016, I won the prestigious research fellowship from European Research Consortium for Information and Mathematics (ERCIM) and, worked as a Research Fellow from June 2016 to May 2017 at the Dept. of Electronics and Telecommunications, Norwegian University of Science and Technology (NTNU), Trondheim, Norway.

From 2005 to 2007, I was employed at Rtronix Communications Pvt. Ltd. in New Delhi, India. At Rtronix, I was responsible for integrating and designing of end-to-end communication systems for VSAT applications and disaster management systems used in Indian Railways, Airways and Navy. Fromm 2007 to 2009, I was employed at Al Bashiri Group, Sana'a, Yemen, one of the largest EPC company of Republic of Yemen, where I was involved with the integration of end-to-end communication systems for mining quarries and multi-dwelling units.

  • Title
    • FD-M2Mcomm: Cross-Layer Full-Duplex Design: Potential for Machine-to-Machine Communications
  • Summary
    • The primary goal of this project is to be able to maximize the end-to-end performance of Machine-to-Machine Communications (M2MCom) systems through Cross-Layer PHY-MAC Full-Duplex (FD) design. It is expected that numerical results over realistic link scenarios will show that this FD design significantly improves the achievable throughput and latency as compared to other key contending technologies like Cognitive M2MCom, non-orthogonal waveform-based unified air interface etc. This FD cross-layer design proposed can successfully address some of the major challenges in M2MCom: a) efficient use of available spectrum supporting large-scale data communication and ever-increasing number of machines, b) energy efficiency through adaptive FD MIMO beamforming c) low latency requirements accomplished through FD operation and efficient spatial reuse, d) self-interference management achieved by switching between FD and half-duplex (HD) modes.

  • Title
    • Experimental Analysis for New Generation Wireless Sensor Networks
  • Summary
    • The primary focus of this research is to understand and summarize the practical implications of either of the contending technologies, using massive MIMO and networks with small cells employing mm-wave links, for prototyping future generation massive and ubiquitous wireless sensor networks. This is accomplished in a two-fold measurement campaign. The campaigns are conducted to account for characterization of the propagation channel between multiple sensors and the decision fusion center, and realistic comparison of receivers and algorithms for fusion centers equipped with multiple integrated antennas.
