Research

My major on-going projects are

For a more complete list of my projects, please go to MCRL home page.

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.

Currently, my primary research interest is on designing autonomous mobile networks, where sensory and adaptation capabilities work in harmony to realize *-agile behaviors.

Research Highlights:

  • We design and implement a cooperative RF scene mapping mechanism using Android-based mobile devices for mobile social network applications.
  • We analyze the computational complexity of communication functions using GNU Radio SDR software to take communication and computation in a unified framework.
  • We designed and experimented Multihop Opportunistic Transmission Protocol (MTOP) that significantly advances the communication efficiency in a mixture of devices with different bit rates. It is being integrated with bandwidth scaling and modulation diversity techniques to further improve the network performance. We also designed Path-centric Rate Adaptation (PRAM) algorithm, which is a cross-layer routing scheme. It is being tested using ns-2 simulation as well as Emulab emulation environment.
  • We investigate uncertainty in mobile networks and methods to overcome are being developed.
  • We design and implement autonomic networking architecture called SINA.

Students

This is a web page with links to alumni of my group.

I have been lucky to be able to recruit a stellar group of students. Current students in my group are:

  • Kushal Shah
  • Robert Fiske
  • Murali Krishna
  • Tianning Shen (co-advisor)

There are many more interesting projects than we can actively pursue; thus, I am currently looking for motivated graduate students. Please take a look at my recent publications listed above to see if you have a reasonable background and if there is a potential match between my research interests and yours. If you feel comfortable understanding, and (potentially) criticizing those papers, please feel free to contact me.

This link contains useful information for graduate students.
