PROFESSIONAL WORK EXPERIENCE

Web Development Lab, University Information Technology Service (UITS)

University of Connecticut, Storrs, CT

Web Developer January 2009 – January 2010

uPortal: release soon

• Collaborated with developers in UITS using TortoiseSVN.

• Developed a portal on Apache Tomcat for students, faculties and staffs based on an open source portal

framework using HTML, XML, XSLT, CSS, JavaScript, Java and SQL. uPortal integrates authentication

and security infrastructures, single sign-on secure access, group management and user customization.

• Developed and configured portlets to access campus applications (PeopleSoft, WebCT, Email, Calendar

and Announcements) and web-based contents (RSS, News, Twitter and Weather).

Research Assistant September 2005 – present

Adaptive Routing and Prediction Assisted Single-copy Routing in Delay Tolerant Networks

• Designed and implemented an object-oriented discrete event network simulator using C++ and STL for

layer structured underwater sensor networks. This simulator includes objects corresponding to real objects

in networks and simulates their behaviors in water.

• Designed an optimal redundancy based energy efficient adaptive routing protocol for delay tolerant

networks. This protocol determines the optimal replication scheduling based on the analysis of the

optimal packets propagation process with continuous Markov model. It was implemented in C++.

• Developed a prediction assisted single-copy routing protocol (PASR) in delay tolerant underwater sensor

networks using C++. Designed a sub-optimal greedy algorithm, aggressive chronological projected graph

(ACPG), to characterize the properties of network mobility for prediction used in routing design.

• Using C++, designed and implemented a distributed practical adaptive routing scheme for reliable data

transfer in delay tolerant underwater sensor networks.

Network Coding and Joint Network Channel Coding in Wireless Networks

• Implementing network coding schemes in underwater OFDM modem using C.

• Developed a joint network channel coding scheme for wireless networks using C++. This scheme enables

reliable data transfer through iterative interactions between random linear network coding and Low-

density parity-check (LDPC) channel coding.

• Designed an energy efficient error recovery scheme for underwater sensor networks using network

coding. This scheme was implemented in C++, Matlab and Network Simulator (NS2).

Multi-path Live Streaming and Overlay Data Transfer via TCP

• Implemented a practical TCP-based multipath streaming scheme, Dynamic MPath-streaming (DMP-

streaming), on PlanetLab using C. This scheme achieves dynamic packets distribution over multiple paths

by implicitly inferring bandwidths on these paths.

• Implemented an iterative application-level multipath rate controller via TCP for data transfer in networks

using C. This controller maximizes the integrated data rate of multiple sources through intelligent path

selection and rate switch over multiple paths.

Structured peer-to-peer networks

• Explored different Distributed Hash Table (DHT) based structured peer-to-peer networks for distributed

applications, including Chord, CAN, Pastry and Tapestry.
