ANN for Wireless Network Applications
September 28th, 2009 by Jason Ernst
This semester I have been taking a soft computing course. We have covered fuzzy logic and are starting artificial neural networks (ANN) although I have missed a couple of classes due to the conferences I have been attending. Anyway the ANN class today piqued my interest in how I can apply this to my area which is wireless networks. It seems to me so far that it could be applied to some of my cross-layer work since the network could be trained to tune parameters to settings which yield good performance based on specific network conditions. However, I’m not sure if this approach would be good or if some other AI type of technique may be better. Also I am interested in how ANNs could be applied to breaking encryption schemes if it is even possible. I have tried a few searches on Google and some journals / conferences but nothing of interest has come up yet. I don’t think I really understand ANNs enough to answer any of the questions, but I thought I’d get them down so I can come back later and think when I have more time. Feel free to leave any comments or suggestions on these ideas.

Problems with Mobile / Wireless Service in Canada
June 2nd, 2009 by Jason Ernst
Today I set out to try to find a replacement for my LG8100 phone which has had a very long and horrible life (going through the washer and dryer several times and still working). I am interested in getting some type of blackberry an iPhone, or would even consider one of the newly popular mobile usb modem sticks. The reason for this is because I want to be able to either tether to my laptop, or use the stick to access the Internet while I travel. For instance I am planning a month long cross-Canada trip this summer. All of the sticks seem to only work on 3g networks. They don’t have information on whether they can fall back onto legacy technology at all. Well this is useless unless I can somehow stick to major metro areas. Not very useful for a “mobile” Internet technology.
Update on the Lack of Updates & PhD Acceptance
April 12th, 2009 by Jason Ernst
Just a quick post to let any readers know why there has been a lack of posts on the blog lately. I have been working like crazy on my thesis with the hope of completing it in the next month or so. I have also been preparing for the AINA 2009 conference I will be presenting at Bradford University in England. Also I have been working on a paper for a conference in Toronto (TIC-STH 2009 I think) with a deadline of May 1st May 31st (extended). So theres been alot going on and not much time.
As soon as I get the thesis completed though I hope to post alot more new content on the blog (as well as a potential redesign since this one seems a little cluttered and busy to me). Check back soon for alot more in-depth info on using ns3 since that is what I have been using for my thesis experiments lately. Update: I am set to defend on May 18th at Guelph. Let me know if you are interested in attending, I will provide more details via email.
In other news, the University of Guelph has officially accepted me to their Ph.D program to start in the Fall of this year (still under Dr. Denko) so I am pretty excited about having the opportunity to continue my research in Wireless Networks. I am still waiting on responses from a couple of other schools (Waterloo & Calgary) so if I end up getting accepted to either of those I will have quite a decision to make. Update: I have accepted a position at the University of Guelph and will be starting there in the fall of 2009.

NS-2.33 and HWMP rev 183 on Intrepid Ibex 8.10
February 16th, 2009 by Jason Ernst
This post is some quick instructions on how to install ns-2.33 and the hybrid wireless mesh protocol (hwmp) on Ubuntu Intrepid Ibex. More detail will be added later, just for quick reference right now.

Guest Article: Why WPA is no longer secure
December 4th, 2008 by Jason Ernst
This is second Guest Article featured on the blog. The article is a brief look at why WPA encryption in wi-fi networks is not secure any longer. Our guest blogger this week is Maya Richard. She describes how brute force attacks can be used against captured packets which have been encrypted with WPA encryption. These attacks have become increasingly practical through the use of graphics hardware which is well-suited to brute force cracking.
