University of Guelph Research Day - Winter ‘08
On December 2nd and 4th 2008, Research Day for the Computer Science Department at the University of Guelph is taking place. Research Day is a day where many of the graduate and some undergraduate students present research projects in various stages. For the graduate students the projects consist of initial results and proposals for thesis documents while the undergrads present results from their research projects.

Fair Scheduling for Wireless Mesh Networks with Multiple Gateways - AINA’09 Submission
Introduction
After quite a bit of work on my M.Sc. degree I am beginning to get some initial results that I hope to use in my thesis. My work seems to be headed in the direction of fair scheduling and load balancing in Wireless Mesh Networks (WMN). For more information on why addressing these issues are important and a PowerPoint presentation see my previous post, “Fair Scheduling & Load Balancing in WMN“. Basically, the aim of my work right now is to try to find a fair scheduling such that throughput and fairness are balanced. See the Venn-Diagram I have created below for an idea of where existing solutions fit into this. My solution would ideally fall right in the intersection of the two circles.

Ns-2.33 (and nam) on Ubuntu 8.04 (Hardy Heron)
Since I have been working with ns2 for the last few months in preparation for my thesis I have decided to write a guide on how to install the most recent version of ns2 on the most recent version of ubuntu (at the time of this writing, Monday June 9th, 2008).
I have found many people already who have had difficulty setting it up so maybe this will be of some help to someone. For this tutorial I am assuming you have installed the most recent version of Ubuntu (8.04). (At the time of writing)

Fair Scheduling & Load Balancing in WMN
My research is becoming more focused as of late towards the area of fair scheduling and load balancing in Wireless Mesh Networks. Earlier this week I gave a talk in our wireless research group at Guelph on WMN: Fair Scheduling and Load Balancing which I will make available at the bottom of the post.
The presentation gave a background on why load balancing and scheduling are important in WMNs. Additionally a survey on the current problems that I find interesting in the area was presented. In case you don’t want to get the presentation / you don’t have MS Office here are the main points from the presentation:

Weasel Words in Computer Science
This week I had the opportunity to sit in on an M.Sc Thesis Defense at Guelph. In most of my courses so far at Guelph the profs have stressed that we should avoid weasel words at all costs in our Thesis and our defense.
The definition of a “weasel word” varies depending on the source but generally they are words which are misleading, make baseless claims or are exaggerations to make ideas sound better. Or like a weasel sucks the insides out of an egg, the weasel word sucks the value out of the document it appears in.
