System-level fault diagnosis

During the pursuit of my PhD, I came across a quite old and interesting area of research: system-level fault diagnosis. One of my committee members actually sensed that my thesis has a connection with that area.

System-level fault diagnosis is a very old research area. The pioneer work was done by F. Preparata, G. Metze, and R. Chien in 1967 (a.k.a. PMC model), which has triggered a lot of follow-up works. An excellent survey can be found here.

My feeling is that the committee was right. I will spend sometime looking into this problem later on and keep posted.

Some stuff related to queue-length-based scheduling for wireless networks

I discussed with my friend yesterday about the implementation of the queue-length-based scheduling for the CSMA networks. We thought that the theoretical side is somewhat mature and it's about time to look into practice.

It turned out somebody has done that. I actually thought that the implementation is quite trivial. I did a similar implementation before. I even implemented a more complicated one. The question for this kind of implementation work is really about the gap between theory and practice.

At the end of the day, it's kinda interesting that my friend, who has been working on theoretical stuff, eventually cares about some practical stuff.

Here are some related paper he sent to me.

My first post

So I have decided to go blogging for various reasons. Here I will post anything related to my research interests.
