Research Descriptions

For network analysis and social applications, the research topics include detection and group therapy of social networks mental disorder, social influence propagation, query processing, privacy preserving, and viral marketing. We also proposed a distributed mining framework for sensor networks and considered uncertain query optimization for mobile environments. The results have appeared in VLDB, KDD, WWW, ICDM, CIKM, ICDCS, GLOBECOM, PAKDD, MDM, DASFAA, TKDD, TKDE, TMC, TSAS. Also, the results have been featured by MIT Technology Review, ACM TechNews,,,,,,, and In addition, the results have received PAKDD Best Paper Running-Up Award, Junior Research Investigators Award in Academia Sinica, K. T. Li Distinguished Young Scholar Award in ACM Taipei/Taiwan Chapter and Project for Excellent Junior Research Investigators in MOST and NSC.

For network optimization and mobile multimedia applications, the research topics include multicast routing, network coding, resource planning, and cross-layer design with analysis. Research results have spanned various kinds of networks, such as software-defined networks (SDN), heterogeneous wireless cellular networks, wireless mesh networks, peer-to-peer networks, satellite networks, Internet backbone, and wavelength division multiplexing (WDM) optical networks. Recently, we proposed a new 3D video multicast algorithm for LTE networks, multicast traffic engineering for SDN networks, a green relay selection algorithm with cooperative communications, and a multicast routing algorithm with network coding. We also designed and implemented a new approximation algorithm for mobile routing and a new video streaming framework for mobile handsets. The results have appeared in INFOCOM, ICDCS, ICNP, GLOBECOM, ICC, WCNC, VTC, ICME, MM, CHI, TMC, TMM, TWC, TKDE, TPDS, and TVT. Also, the results have received Best Paper Nominate of IEEE GLOBECOM, Best Student Paper Award of IEEE ICME, ACM CHI Best Paper Honorable Mention Award, Best In-Session Presentation Award of IEEE INFOCOM, ACM SIGGRAPH Asia Emerging Technologies Prize, Exploration Research Award in Pan Wen Yuan Foundation, and Career Development Award in Academia Sinica.
