What's New?

I successfully finished my Ph.D degree on April, 2009.
I have joined Deutsche Telekom Inc., R&D Labs USA as a senior research scientist on May, 2009.

About ME

I was a Ph.D Candidate in Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor. I conducted research under the guidance of Prof. Kang G. Shin in Real-Time Computing Laboratory (RTCL).

Research Interests

My research interests lie in wireless networks (mesh networks, cognitive radios, MANETs, WLANs, and WWANs), mobile computing, and distributed/embedded systems. Under these exciting areas, I have been exploring the key system attributes, including Quality-of-Service (QoS), fault-tolerance, performance, and manageability.

Selected Research Projects

  • Mobile Wireless Router Systems
    With collaboration with NEC Labs, I have designed and developed mobile wireless router systems that autonomously identify the best signal reception position through physical mobility. In addition, I have developed, implemented, and prototyped autonomous multi-hop wireless relay systems that provide instant wireless connectivity through a group of mobile robots (2007-2008).
  • Self-Healing Multi-radio Wireless Mesh Networks
    I developed localized self-reconfiguring algorithms for a multi-radio WMN to autonomously recover from wireless link failures. I also constructed a multi-radio WMN testbed in the Computer Science and Engineering building at the University of Michigan, and extensively evaluated our algorithms in the testbed (2006).
  • Link-Quality Measurement in Wireless Mesh Networks
    I developed a high-accuracy and low-overhead link-quality measurement framework, called EAR, tailored for Multi-hop Wireless Mesh Networks (WMNs). I also constructed an indoor WMN testbed in the EECS building at the University of Michigan, and extensively evaluated our framework (2005).
  • Mobile Collaborative Community (MC2)
    With collaboration with HP Labs, I envisioned a novel network service model, called a mobile collaborative community or a community, that delivers high-throughput wireless wide-area connectivity to a group of multi-homed mobile users in proximity. Furthermore, in the community, I developed a proxy-based inverse multiplexer, called PRISM, that enables TCP to efficiently utilize the community members' WWAN connections, achieving aggregate bandwidth (2004).
    Note that the above projects have been supported in part by NSF, AFOSR, Intel, and NEC.
