Hi, welcome to Shu Du's homepage. I am a 6th year graduate student at the Department of Computer Science, Rice University. I am working with Professor David B Johnson on the Monarch Project in the System Group here. Before I joined Rice in 2001, I was studying at the Department of Computer Science and Technology, Tsinghua University, in Beijing, China, where I received my Bachelor Degree of Engineering and Master Degree of Engineering in 1999 and 2001, respectively.  When I was a graduate student at Tsinghua, I was working with Professor Dongsheng Wang on the applications of the parallel workstation cluster system.

Recent Research Activities 
The project is developing a new sensor network MAC protocol to improve network performace and save the sensor node energy. [source code download] The project is developing a new sensor network architecture whose communications hierarchy is aligned with the information flow of its computations. The project is to devise efficient and scalable common communication architecture and thereafter activate the traditional Internet services in a large-scale citywide ad hoc network. This work is built based on a newly proposed self-organizing hierarchical address assignment protocol in the distributed system. [source code download]
This project is to devise a testbed environment, in which any ad hoc network routing simulation model in the popular network simulators, like NS-2, can be used directly as a user-level implementation in FreeBSD/Linux without the change of a single line in the source code. This project is to provide a distributed self-organizing hierarchical address assignment protocol in the energy- and resource-restraint sensor network. After the hierarchical address is assigned, routing in the network is becoming trivial. This project is to explore the area of efficient routing maintenance in the ad hoc network. Instead of initiating the expensive broadcasting packets every time to collect routing information, I was looking into several strategies that can locally repair the broken route and can use them adaptively to achieve high performance with low overhead
