My general research interests include wireless networks, sensor networks, mobile computing, and parallel and distributed systems. I lead the Mobile Computing Research Laboratory (MCRL) at Cleveland State.

Research Highlights:

  • Indoor localization based on RF fingerprints is not new but we found it is not straightforward in a large scale venue. We surveyed the RF scene at a large venue (505x237m2) and revealed challenges as well as proposed solutions (Mobiquitous, Tokyo, December 2013).
  • Mobile hotspot is useful to provide connectivity to Wifi-only devices. We designed energy efficient mobile hotspot and implemented with pseudo null and pseudo beacon frames in the context of virtual AP framework. (IEEE INFOCOM, Toronto, April 2014)
  • Security at the physical layer attracts attention due to its low complexity. We studied physical layer watermarking based on information redundancy in spread spectrum communication in Wifi and Zigbee protocols. This work is implemented using USRP/GNU Radio software radio platform. (IEEE MILCOM, San Diego, November 2013)
  • Security of electronic systems have emerged as a serious concern. With increasing connectivity and ease of access to these systems, the security vulnerability is increasing at an alarming pace. This project is intended to provide a holistic view on information and software security as well as hardware security. In particular, hardware security attacks such as hardware IP piracy, side-channel analysis, fault injection, and clock glitching are a growing concern to both semiconductor industry as well as end users. Our work is based on Altera FPGA prototyping systems and Quartus. (National Science Foundation, TUES Award #1245900, September 2013)
  • The increasing popularity of 4G-capable mobile devices such as smartphones and tablets has brought a lot of attention and concern on the security and privacy of 4G communications. In comparison with the 2G and 3G mobile networks, 4G networks use adaptive modulation and coding to provide constant network access with much higher bandwidth to these mobile devices. We study security and privacy of 4G communications, fast indoor positioning in large-scale, chaotic venues, efficient modulation and coding for 4G mobile communications, characterizing the noise in wireless channels with statistical physics approaches, and secure medical communication systems. (National Science Foundation, MRI Award #1338105, September 2013)
