Topics for Class Projects in Distributed Computing 2017:

  1. The projects are done in pairs.
  2. We will schedule with each project during June 10 July 10 to meet and go over the presentation and discuss your project.
  3. The idea is to take a topic (which would typically cover two or three tightly related papers), and try to suggest an improvement, or a variation, or to suggest a problem with the papers etc.
  4. Each project should submit two to three pages that summarize the research done, and a 15 minutes presentation.
  5. Let me know if you encounter difficulties in finding any specific paper(s).

Here are some suggestions for topics for the class project. Better yet would be if you can come up with your own idea/suggestion, please talk to me. The deadline for the projects is June 16.

To find good topics you can go over the papers presented in (use google search) different years for the following conferences: PODC -2018 / PODC-2017/2016/2015, or DISC2018

 / 2017/ etc, or SIGCOMM, or SPAA, Infocom, SODA, etc. Find them on the internet and find the pdf's of the relevant papers. To find relevant papers use scholar.google. https://scholar.google.co.il/ to find papers that had referenced a particular paper, or papers on different topics. Here are some possible topics in a random order. These are just examples!:
