Course Project The course project in CS5470 is an open-ended networking research project. You will divide into teams of up to two to carry out the project. You may also choose to work by yourself on the project. Your project can be either of the following types: design, implementation, measurement, analysis using simulation tools such as Mininet, NS3 and OPNET. The goal of the project is to experiment with new research ideas and solutions. The final project report should aim for a conference quality paper.

What to Submit Project proposal, due: 03/05/2017. 2 pages. The project proposal should have the following contents: (1) background, (2) related work, e.g., the existing solutions and their limitations, (3) your proposed new idea and solution, explaining its novelty and research challenges, and your plan or schedule of the project implementation. Project code/demo, due: 04/23/2017. The code/demo could be either simulations or experiments. Project presentation slides, due: 04/23/2017. The presentation should be 20 mins, plus 5 mins Q&A. Final project report, due: 04/23/2017. The final project report should be 4-6 pages with conference paper quality. The report should include (1) title and authors, (2) abstract, (3) introduction (e.g., background, related work, novelty and challenges in your project, an overview of your solution and results, and the organization of the report/paper), (4) problem statement, (5) description of your proposed idea and solution, (6) performance evaluation, e.g., the simulation results, (7) conclusion, and (8) reference. Note: both the project proposal and the final project report should follow the format of IEEE conference template here: http://www.ieee.org/conferences_events/conferences/publishing/templates.html

Academic Honesty No tolerance on cheating! FAIL the course on the FIRST attempt! Consult the University Statement on Academic Integrity: http://ecatalog.calstatela.edu/content.php?catoid=1&navoid=26 For the programming assignments: They are collaborative projects with a team of two students. Between different teams, discussions of ideas are welcome, but exchanges of source codes are not allowed. Use of segments of code found online is allowed provided the student explicitly cites the references used. Note that copying the whole solution from online resources and/or copying code from past year assignments is still considered cheating even if you cite the sources. Students who do share their work with others are as responsible for academic dishonesty as the student receiving the materials. Students are not to show work to other students, in class or outside the class. Students are responsible for the security of their work and should ensure that printed copies are not left in accessible places, and that file/directory permissions are set to be unreadable to others.
