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 <a href="http://portal.acm.org/citation.cfm?id=152610.152612">here</a>.<br /><br />My feeling is that the committee was right. I will spend sometime looking into this problem later on and keep posted.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-7969555598045872585.post-657490398693387732010-07-26T16:46:00.000-07:002010-07-27T13:04:49.711-07:00Some stuff related to queue-length-based scheduling for wireless networksI discussed with <a href="http://www.locxuanbui.com/">my friend</a> 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.<br /><br />It turned out <a href="http://www.princeton.edu/%7Echiangm/implementuocsma.pdf">somebody has done that</a>. I actually thought that the implementation is quite trivial. I did a <a href="http://www.nvhoang.com/uploads/icc07.pdf">similar implementation</a> before. I even implemented <a href="http://www.nvhoang.com/uploads/idsrt-qshine09.pdf">a more complicated one</a>. The question for this kind of implementation work is really about the gap between theory and practice.<br /><br />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.<br /><br />Here are some related paper he sent to me.<br /><a href="http://www.eecs.berkeley.edu/%7Eljiang/ToN_CSMA.pdf">http://www.eecs.berkeley.edu/~ljiang/ToN_CSMA.pdf</a>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-7969555598045872585.post-54585153694853951862010-07-26T15:33:00.000-07:002010-07-26T15:37:12.928-07:00My first postSo I have decided to go blogging for various reasons. Here I will post anything related to my research interests.Unknownnoreply@blogger.com0
