Student Assessment (Project)
 CPE 400 (Due: Monday, Nov. 23rd)
 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

11. Course Overview

Student Assessment (Project)
 CPE 600 (Due: Monday, Nov. 23rd)
 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 (http://www.comsoc.org/cst) Journal for potential publications
