Representative research history:

July 2007 - March 2008
Lecturer, Computer Science, Witwatersrand University, won the competitive Faculty of Science Top Slice Funding from the University of the Witwatersrand, Johannesburg. The winning proposal involved building a flexible wireless mesh network test-bed to be used to investigate feasibility of providing voice and video communication services to low income communities in Johannesburg.

 

Nov 2005 - June 2007
Senior Research Associate- School of Computer Science and Engineering, the University of New South Wales, Australia

  • Developed QoS framework for community wireless mesh networks.
  • Investigated streamlined Medium Access Control (MAC) protocols.
  • Wrote and presented project progress reviews at quarterly project leaders’ meetings.
  • Supervised PhD students working in wireless mesh networks research.

 

Aug 2001 - January 2006
Ph.D. Candidate - QoS in 802.11 wireless LANs
Proposed a novel service differentiation mechanism for contention MAC based on the capture effect. This technique is attractive because in its basic form, its completely decentralised and requires no modifications to mobile hosts and access points. Features include an enhanced option for transmission power control and arbitration for improved performance.

  • Employed Markov Models, Qualnet, and Matlab simulations to evaluate the performance of the proposed service differentiation technique

 

November 1998 – July 1999
M.S. candidate – VoIP opportunities, services, challenges and products
Investigated QoS in VoIP networks, with emphasis on available and future services, technical challenges affecting wholesale deployment  and available products for the different VoIP market segments.
