Course Overview 10 Student Assessment (Project)  CPE 400 (Due: Monday, Nov. 23 rd )  One Network Programming Project  Individual project  Decide on a particular network protocol or application and simulate the protocol/application using program  Confirm your protocol to Instructor as early as possible  Submission will require a paper turning in code that compiles and runs properly a report documenting the code and a report explaining the functionality of the protocol any deviation from ideal behaviors expected (out of the box thinking!) If the project results in an outstanding demo, that will be posted on Instructor website and will be sent to a potential demo conference or workshop  Python, C/C++, or Java would be ideal for the programming project

Course Overview 11 Student Assessment (Project)  CPE 600 (Due: Monday, Nov. 23 rd )  One Research Paper Project  Individual project  Discuss with Instructor and decide on a particular network topic that will not be covered in class  Write an IEEE survey & tutorial style paper on that topic emphasizing Related works on that topic Potential open issues and challenges Providing potential solution directions for those challenges  Submission will require An IEEE survey & tutorial style paper following the IEEE format Any program with code documentation (if applicable) Outstanding papers will be sent to IEEE Communications Surveys & Tutorials ( Journal for potential publications
