Short Bio

Shicong Meng is currently working toward the Ph.D. degree in Computer Science at Georgia Institute of Technology with Prof. Ling Liu. His research interests center around distributed system and related data management. Before he came to Georgia Tech, Shicong Meng received his M.S. degree and B.S. degree in China, both in Computer Science.

Research


Scalable and Cost-Effective IPTV Grid (08/2007 - present)

  • Identified the underlying class-constrained multiple 0-1 knapsack problem in IPTV grid.
  • Proposed a scalable IPTV grid capable of approximating optimal request assignment.

IR and DB management in Large-scale Distributed Systems (01/2006-03/2007)

  • Presented a theoretically proved approach to support efficient linear recursive query evaluation in DHT network with randomized graph fragmentation and execution tree formation.
  • Implemented a locality sensitive search system on DHT network via locality sensitive hashing (LSH) techniques. Identified the heavily skew distribution of documents caused by LSH and participated in the research on balancing the workload.

Large-scale Overlay Systems Performance Study (01/2005-07/2005)

  • Applied reinforcement learning for building query-content-oriented routing indices in Gnutella. Proposed a formalized update strategy which explicitly approximated the expectation of returned results and determined its fast learning speed.
  • Studied Gnutella stream with randomized time-series analysis and built its applications in result caching and load balance for structured and unstructured systems.

Peer-to-Peer Network Measurement Study (09/2004-12/2004)

  • Built a distributed crawling system capable of collecting all queries of Gnutella 0.6 overlay and statistically studied query arrival model, content purity and peer selection.
