Research Interests

Research Description

I have worked on some fundamental problems in the areas of parallel and distributed processing, wireless networks, optical networks, and peer-to-peer (P2P) communications. My contributions have helped advance the frontier of knowledge in those areas. In particular, I have worked on the problems of network routing, parallel and distributed sorting, task scheduling in parallel and distributed systems, medium access control of Wi-Fi and Bluetooth, data aggregation in wireless sensor networks, dynamic spectrum access control in cognitive radio networks, wavelength-division multiplexing (WDM) MAC design, P2P protocol design, and cloud computing. The fusion of computer and communications is redefining the way we do computing. There has also been significant progress in interconnection mechanism and data transmission technology. Together with the new styles of software design, including virtualization technology, they have engendered a new Internet-based computing paradigm, called cloud computing, that offers cost-effective services. In order to make cloud computing secure, efficient, and easily programmable, my current research also focuses on developing efficient algorithms, system software and tools for cloud computing.
