Research Interests

The goal of my group's research is to devise efficient algorithms for transporting a variety of traffic over Internet, wireless mobile network, sensor network, social network, content-oriented network, and local/home area networks. This includes access control, admission control, traffic measurement, congestion control, traffic scheduling, caching, multicast routing, and terminal/router/server architecture design. The research challenge is enormous because the solutions should be scalable over a wide range of speeds, number of users, and distances. The research results are applicable to design of efficient network protocols, networked systems, and new applications. His research interest includes mobile network algorithms and protocols. He is also interested in policy issues on science and technology, and in promoting startups.
