Profile

I defended my Ph.D. thesis in Spring 2009 and my thesis title is "A Systematic Security Approach for Wireless Mesh Networks". My advisor is Prof. Johnny Wong.


Now I work for Google Inc.


My research interests include wireless (ad-hoc/mesh) networking and security, intrusion detection, intrusion response, key management, and congestion control.


My work is related to the following research topics:
  • Security Mechanisms in Wireless Mesh Networks
    • Heterogeneity-aware framework for group key management in wireless mesh networks
    • Intrusion detection and intrusion response in wireless mesh network
    • Apply maching learning algorithm in IDS
    • Cross-layer design of IDS in multi-radio wireless mesh networks
  • Intrusion Detection in Wireless Ad-hoc Networks
    • Hybrid intrusion detection techniques in wireless ad hoc networks
    • End-to-end detection of wormhole attack
    • Machine learning method in feature selection
  • TCP Performance and Congestion Control for Wireless Networks
    • Proposed TCP-Eaglet protocol to improve TCP performance in wireless networks
