IEEEE CCECE 2014 and Cognitive Agent Simulation

This past week I attended IEEE Canadian Conference on Electrical and Computer Engineering (CCECE2014) in Toronto, Canada. I was there because of two papers I was a co-author on. The work was part of a side project I was involved in on cognitive agent simulation. The idea was inspired by the observation that in the spring time, many newborn animals are struck as they cross the street. Later in the year, it seems that fewer animals meet this fate. So have the animals which survived observed the doomed creates being struck, learned something about the environment, and managed to become more intelligent? We aimed to model this type of environment, and then re-create the most basic intelligence to try to replicate this behaviour with a cognitive agent.

I was responsible for implementing the simulation tool and the naiive learning algorithm which we also presented at the conference. The simulator was created in c/c++ and was designed in such a way that later on the intelligence algorithms could be swapped out, so that we could also experiment with more sophisticated learning algorithms.

Tutorial: Install ns-3 in Windows 7 using cygwin

Ns-3 is one of the most popular simulation tools for network simulation. See the website: http://www.nsnam.org/. It is the successor to the popular ns-2 simulator. The tool is written in c++ / python, but I manage to get by using mostly only c++ (as opposed to ns-2 which uses c/c++ and tcl). One major difference between ns-3 and ns-2 is that this version has been designed for wireless network simulation from the ground up. (There is support for many types of 802.11 networks including 802.11s mesh networks which interest me).

AINA 2009 Conference Presentation

This past week I travelled to the UK to present at my first International Conference – Advanced Information Networking and Applications (AINA 2009) in Bradford, UK. My presentation was on “Fair Scheduling in Wireless Mesh Networks with Multiple Gateways”. The paper for the conference was published in the main AINA conference and I presented on the first day, in the first session. It was nice to have it over with right away so that I could relax and focus on meeting as many people as possible at the conference.

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.

Tutorial: 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)
