Studentship, The RELATED JOB
EXPERIENCE Versitech Ltd., HK
(a technology transfer company owned by
HKU) Java Consultant, Sep 2000 – Jan
2002 Involved in the development of two Internet banking projects in
partnership with IBM: analyzing business logics and user requirements;
drafting design specifications using universal modeling language (UML);
providing technical advices to developers; implementation and testing. Authorized
Academic Java Campus, HKU, HK IT Engineer, May 1998 – August
1998 Development of a prototype that used authentication tokens for user id
verification; Organizing IT exhibitions and seminars. Northern Telecom,
HK Summer Intern, May 1997 – Aug
1997 Assisted in launching a PCS cellular network in HK: review on mobile
cellular technologies; design and implementation of a database application
for monitoring the deployment progress of BTS sites; base station performance
testing under the supervision of senior engineers. RESEARCH/PROJECT
EXPERIENCE Information Theoretic Routing in Sensor Network, Sep 2003 – now This research aims at minimizing the overall transmission energy in a
sensor network by optimizing the data aggregation performance through the use
of multidimensional sampling techniques. Alpha Tree in Sensor Network, May 2003 – Aug 2003 The alpha tree
algorithm allows the routing topology to vary between a minimum depth tree (a
= 1), for zero
data compression, and a minimum
spanning tree (a
= 0), for 100%
data compression (multiple messages in and one message out), in order to
minimize the energy cost for data funneling. Service Differentiation in Stateless Wireless Ad Hoc Networks (SWAN), Mar 2002 – May 2002 SWAN was a stateless network model which
used distributed control algorithms to deliver service differentiation in ad
hoc networks. It employed rate control for UDP and TCP best-effort traffic,
and sender-based admission control for UDP real-time traffic. The project
extended the preliminary SWAN prototype to work on an existing implementation
of AODV (Ad hoc On-demand Distance Vector). Resource Allocation through Real-Time Auctions, Mar 2002 – May 2002 The project simulates a progressive second
price (PSP) auction game for the allocation of network resources. Two different
bidding strategies were implemented and their performances, like time to
reach the Nash equilibrium, are compared and analyzed. The Secure Object Spaces for Global Information Retrieval (SOSGIR), June 1999 – Aug 2000 This research aimed at integrating loosely
coupled, globally distributed heterogeneous databases by the use of object
space technology. Public key cryptography is employed to protect the object
space against malicious attacks. A proof-of-concept prototype was built, with
its performance evaluated. Mobile Robot: Exploration and A program was written to control a mobile
robot through the radio ethernet so that it could explore an unknown
environment without running into an obstacle and at the same time draw a
floor plan by processing the sonar data collected by the robot. TEACHING
