    Course Overview:
  • There is no textbook for this course. I will cover majority of the topics through lectures on important concepts, and presentation of related papers. The remaining classes will comprise of student-led presentations. Each student will be required to present 1 paper in the entire semester.
  • For each class, students are required to read 2 of the assigned papers and write reviews for them (in certain cases there will be only 1 paper for review). Most of the papers are from top networking conferences. The reviews should be emailed to the TA before class starts. Also, a printed copy should be submitted in class.
  • Several additional papers will be recommended for reading. You should make an effort to read them, but I understand your time constraints.
  • There will be one mid-term exam (open notes, open laptop), and no final exams.
  • The most important component of the course will be the final research project. You are expected to do these projects in groups of 2 (preferrably). I encourage you to think about the project problem early, discuss your ideas with me, read papers in the area, formulate your solution, and finally implement it.

     
    Class Projects:
  • The class will end with a final project competition, which involves presenting your project and writing a term paper. In the last two years, researchers from Cisco and Duke faculty judged the contest. The 3 best projects were awarded the Cisco Champions award.
  • This year Microsoft Research will provide tools, services, and equipment for creating mobile applications ... this is part of a HAWAII project in which Microsoft Research is engaging with 3 universities to encourage research in emerging directions in mobile computing.
  • See HAWAII project website here   MSR
  • Like prior years, Cisco will also sponsor prizes to the top 2 or 3 projects.      cisco
