Most are in areas relating to my research interests, primarily network dependability (reliability), but that can cover many technical areas (e.g. wireless, routing, transport protocols, applications, peer-to-peer, etc).
I may be willing to supervise theses on other topics in networking if there is a very good match between your interests and background and mine. Please email me a short description of your proposal.
This web page lists several possible topics intended for undergraduate theses. They reflect my research interests, and so could be expanded (vastly, especially with more emphasis on fundamental theory than practical implementation) to form Masters or PhD theses.
I cannot possibly do a good job of concurrently supervising all of these projects, and generally only supervise 4-6 BE students per semester. Consequently, acceptance of students for topics will be done on a competitive basis, with the best qualified students getting first choice. I'm flattered by emails that I receive from students around the world asking if I can supervise them doing these projects, but I can only supervise students at UNSW.
If you are interested in any of these topics, then please email your resume and academic record(s) to t.moors AT unsw.edu.au . The earlier you do that and can commit to a thesis (by completing a Thesis Nomination Form, available from the school office), the broader your choices will be.
For information about past theses that I have supervised, see http://uluru.ee.unsw.edu.au/~tim/netskunks/index.html#past_projects
