After 24 months of graduate studies at UBC, I finally fulfilled all the requirements for my M.A.Sc. degree.  The title of my Master's thesis is "Quality of Service Enhancements in IEEE 802.11 Wireless LANs."  The thesis was submitted to the UBC library on September 30, 2003.  Following the completion of the Master's degree, I will no longer update this homepage.  I am now working in Fortinet Technologies (Canada) Inc. as a Junior Hardware Engineer for computer motherboard design.

INTRODUCTION

 

I am a M.A.Sc. candidate in the Department of Electrical and Computer Engineering at the University of British Columbia.  As a graduate student and a Research Assistant in the Communications Group,  I am studying and researching on wireless and computer networks under the supervision of Dr. Robert W. Donaldson.  Besides my study and research, I am one of the teaching assistants in EECE474.

 

 

BACKGROUND

I received my B.A.Sc. degree from the Department of Electrical and Computer Engineering at the University of British Columbia.  During the undergraduate degree, I concentrated my studies on communication networks and participated in the IEEE Amateur Paging Project under the supervision of Dr. David G. Michelson.  To acquire further knowledge in mobile communication networks, I entered to the Master's degree program in the same department.

    

 

 

 

 

RESEARCH

 

My research focuses on medium access control (MAC) protocols for real-time traffic in IEEE 802.11 wireless local area networks (LANs).  The Internet Engineering Task Force (IETF) is currently specifying service differentiation on the Internet and the result is sub-optimal without lower layer’s support.  With the growing popularity and acceptance of 802.11 wireless LANs, it is essential to focus on Quality of Service (QoS) support at the MAC layer of the 802.11 standard.  The goal of the research is to design and evaluate a backward compatible MAC protocol for providing QoS in 802.11 wireless LANs.  Click here for a brief tutorial on 802.11 wireless LANs.

UBC is deploying 802.11 wireless LANs using 1,200 Cisco Aironet access points to provide ubiquitous wireless Internet access across the campus.   Click here to find out more information from Cisco.

The files are in Microsoft PowerPoint format.  Should you have any comments or suggestions regarding my presentation slides, please contact me at georgew@ece.ubc.ca.  

 

 

CERTIFICATES

   

I am a holder of the following certificates:

  

  • Cisco Certified Design Associate (CCDA)

  • Cisco Certified Network Associate (CCNA )

  • Sun Certified Programmer For Java 2 Platform

  • Amateur Radio Basic and Advanced Certificates (Industry Canada)  

I am currently pursuing Cisco Certified Network Professional (CCNP) and have completed the Routing Exam 640-503 and the Switching Exam 640-604, two of the CCNP required exams.  

 

 

 

WORK EXPERIENCE

 

After having completed my undergraduate degree at UBC, I joined the R&D department of the ITE SmartCard Solutions Limited, a wholly subsidiary of ITE (Holdings) Limited, as an Electronic Engineer being responsible for developing embedded software for smart cards.  Most of my previous work was related to smart card security protocols that are relatively trickier than the network communication protocols on which I am presently researching.  Currently, I am a Research Assistant and a Teaching Assistant in the Department of Electrical and Computer Engineering at UBC.

    

 

 

MOBILE HOMEPAGE

 

Just for the sake of fun, I built a simple mobile homepage that uses WAP/WML.  You can view the mobile homepage at http://www.ece.ubc.ca/~georgew/index.wml using a cell phone with WAP support.  If you don't have a WAP phone, click here to access my mobile homepage using your Web browser.

 

 

 

SMS

 

I have created a wireless e-mail address, georgew+wireless@ece.ubc.ca and you can now send me SMS via this wireless e-mail address.  Feel free to send me SMS when waiting for me to check my e-mail just isn't an option.  Please keep it short since my mobile phone carrier only supports SMS with text messages of up to 160 characters.

 

 

MOBILE ROBOT

I am a robot enthusiast.  Currently, the first prototype of a six-leg mobile robot is under development.   The Java programming language is employed in developing software for controlling the robot and therefore, the controlling software is supposedly platform independent.  Click here for further details of the first prototype.  If time persists, the second prototype of the robot will carry an embedded Linux board or a PDA and Wireless Ethernet, IEEE 802.11,  will be used as the communication technology between a PC and the robot.
