Graduate Research Assistant, August 2001 ~ Present

• Trust management in distributed self-organizing networks: to theoretically understand network dynamics in the application of trust management

  • Investigated trust evaluation algorithms based on graph theory, Markov random field and research in statistical physics

  • Studied the convergence behaviors and phase transition phenomena of the evaluation algorithms

  • Investigated the effects of network topology on distributed evaluation algorithms, such as convergence speed and attack resistance, and demonstrated that without a few trusted cluster-heads distributed evaluation algorithms based on local policies such as majority voting do not establish trust for the entire network.

  • Applied cooperative game theory in self-organizing networks where nodes are selfish, and proposed mechanisms (trust and negotiation) that promote collaboration among nodes

  • Designed a trust evidence distribution algorithm inspired from swarm intelligence, simulated and demonstrated effectiveness of the distribution algorithm in mobile ad hoc networks using NS-2

• Security in wireless networks

  • Developed a risk-based secure routing algorithm for mobile ad hoc networks

• Dynamics of networks in multiple disciplines

  • Investigated dynamics of complex networks, such as small-world networks and scale-free networks

  • Modeled biological neuronal network as a Markov random field, and solved the optimal neuron layout problem in C. elegans using Gibbs sampling method

Summer Intern, June ~ August 2005, Mentor: Dr. Helen J. Wang (helenw@microsoft.com)

• Location privacy in wireless networks

  • Investigated location-privacy threats in existing wireless networks

  • Proposed solutions that protect location privacy of users, including anonymous authentication scheme based on blind signature, opportunistic silent period and passive transmit power control to reduce location precision

  • Designed a location-privacy protecting system

• Wireless network testbed

  • Setup an 802.11 WLAN testbed and implemented operations of the location-privacy protecting system on laptops with wireless cards.
