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.

Cluster Computer Case Suggestions?
So I’ve recently come across a bunch of free computers and I’ve decided to try to hook them together to form a beowulf style cluster for running some of my simulations on since I think I can modify the code to be parallel. I have tested all of the computers and have them spread across my basement floor however I seem to have a problem. I need a way to enclose them into some sort of case or storage area. I don’t want to use wood and have been exploring some kind of plexiglass or similar material without much luck. So far the best idea I’ve seen has been the “Microwulf“.

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)

Customized Reconfigurable Interconnection Network Paper Accepted to COCOA ‘08
Yesterday I found out that a paper I helped out with got accepted to COCOA 2008 Conference in St. John’s Newfoundland. This is the first academic paper I have worked on, and also the first one that has been accepted to a conference so I am extremely excited.

Java Discrete Event Driven Simulation
Recently in my Networks course at Guelph they had us create an event-driven discrete simulation to model both a wireless network and a switch. For the project I got a hexagonal geometry for the wireless network which was to be arranged similar to a Manhattan Street Network with each node having at most six neighbours. Other groups got triangular and square geometries for this portion. For the switch I got an 8×8 Banyan switch. Other groups got the crossbar switch or backplane switches.
