BWCCA 2010 – Adaptive Mixed Bias Resource Allocation for Wireless Mesh Networks

Today I presented a recent paper on “Adaptive Mixed Bias Resource Allocation for Wireless Mesh Networks” at the BWCCA conference in Fukuoka Japan. The paper is authored by myself and Thabo Nkwe from the University of Guelph. The abstract is below:

In wireless networks, conditions may change rapidly and unpredictably. Often wireless networks are not designed to adapt to these changing conditions and perform poorly when they become congested. The multi-hop broadcast nature of wireless mesh networks amplifies the problem of poor wireless performance. Mixed bias scheduling has previously been applied successfully to wireless mesh networks however, it still suffers from similar problems when conditions change rapidly. In this work we propose an adaptive mixed bias (AMB) algorithm which uses a tabu search approach to change based on delay and dropped packets in the network. The proposed scheduling approach consists of three important algorithms, namely, the tabu search algorithm, move generation, and utility function. The adaptive mixed bias approach is compared against IEEE 802.11 and the non-adaptive mixed bias approach. The performance is evaluated using the packet delivery ratio and average end-to-end delay metrics.

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.


Thesis Defense a Success!

Last Friday I successfully defended my thesis at Guelph. The room was full with lots of friends, students and faculty and everything went fairly smoothly. It definitely feels great to be done after almost two years building up to this. Today I finished the final revisions and submitted all of the copies with an insane amount of paperwork to Grad Program Services. Two to three weeks from now I should get my final bound copy of my thesis and it should soon be available online and in libraries :). For anyone interested in reading it, email me and I can send you a pdf copy.


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:
