EDUCATION

· Ph.D., Electrical Engineering and Computer Sciences, University of California, Berkeley, with Designated Emphasis in Communication, Computation and Statistics, December 2005.

• Research Group: Sensor Networks for Vehicle Detection
• Thesis topic: “Wireless Sensor Networks: Energy Efficiency, Delay Guarantee and Fault Tolerance”
• Designed and implemented an energy efficient system for sensor networks with an emphasis on monitoring vehicular traffic. Analyzed magnetometer sensor data for vehicle detection, classification and re-identification. Designed a system that meets the battery lifetime, delay guarantee and fault tolerance requirements of sensor networks at multiple protocol layers. At the MAC layer, the transmissions of the nodes are scheduled to minimize the delay and energy consumption. At the routing layer, the optimal routing paths are formulated as a linear programming problem and then approximated by a sequential distributed algorithm. Delay guarantee and multiple paths are then incorporated into this formulation. At the application layer, data compression, oversampling of the sensor field and placing extra relay nodes are used to save energy and provide redundancy.

· M.O.T, Management of Technology Program, HAAS Business School, University of California, Berkeley, December 2004.

· M.S., Electrical Engineering and Computer Sciences, University of California, Berkeley, December 2002.

• Thesis: “PEDAMACS: Power Efficient and Delay Aware Medium Access Protocol for Sensor Networks”
• It is well known that there is a trade-off between delay and energy in general ad hoc networks. I designed a communication protocol that simultaneously achieves energy efficiency and delay guarantee by using special characteristics of sensor networks. The lifetime of a sensor network increases from several days to several years with PEDAMACS. PEDAMACS is patented at UC Berkeley.
