Updated: NS-2.33 and HWMP rev 183 on Intrepid Ibex 8.10
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
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.

Ns-3.2 on Ubuntu 8.04 Hardy Heron
For the next stage of my thesis instead of using the well known ns-2 simulator as originally planned, I have opted to instead use ns-3. I have chosen this particular environment because it seems to be designed from the ground up to be a wireless simulation tool while ns-2 was originally designed solely for wired network simulation. I have made some use of ns-2 however, so if you are looking for a guide to getting that working in Ubuntu see my post “NS-2.33 on Ubuntu 8.04 Hardy Heron“. In addition to this, ns-3 no longer uses the tcl scripting language. Instead the choice of pure c++ or a combination of c++ and python may be used to define the simulation parameters. I prefer this approach because I have no desire to learn tcl and find the c++ ns-3 ot be more intuitive than ns-2. Additionally, this guide will be used as a reference for myself while I learn the ns-3 environment. Check back for regular updates and useful infromation.

PerWin Research Group @ the University of Guelph
Today I completed the listing page for all of the presentations our research group PerWin at the University of Guelph has made in the last year or so. PerWin stands for Pervasive Computing and Wireless Networking Research. The group is directed by my advisor, Dr. Mieso Denko and has several graduate students who are active research members in the group. We have given presentations on topics ranging from Wireless Mesh Networks protocols, Autonomous networks, Fair Scheduling, Load Balancing, RFID, Wireless Security and much more. We have also had special invited talks by several faculty members from various Universities around Ontario (Ryerson, UOIT).
Reynolds Building @ University of Guelph where PerWin meets regularly
Check out the schedule page here for the list of presentations, presenters and topics. There are also listings of many of the websites for the presenters which may be a good resource for people interested in our work. If you are a faculty member interested in giving a talk contact Dr. Mieso Denko at the University of Guelph.

Guest Article: 5 Blogs and Sites for All Things Wireless
I recently received a request for a guest contribution to the blog from Kelly Kilpatrick so I thought it would be a nice change to have some content from someone other than me. The article is a compilation of some good sites for the latest on wireless technology and news.
