# **Welcome to the Special Topics in Communications: Networks - Q21 Wikia**

## Instructions

The final project (required only from the graduate students) is a student-selected research project that applies networking principles in our everyday applications by looking at how our world is connected socially, strategically and technologically and why it matters. In other words you need to propose a Q21 similar to the 20Q to be covered in this course that utilizes networking concepts to address the proposed question. The proposal should be 1-2 pages and should provide a detailed description of the question you are trying to address. You should convince the reader that the problem addressed plays a significant role in our networked life. You should also state what you plan to deliver at the end of the project. You should include a short list of references that are related to your project. If it is a joint project, you should state the planned division of work. I will give you feedback on your proposal. Be careful not to propose an overly ambitious project since everything must be done within the semester.

**The final project could be a collaborative project with at most three students.**
If a collaborative project is pursued, the scope of the project is expected to be about twice that of a one-student project, and the works of each student must be clearly stated so that I can grade them separately. Start immediately with your project! Think about what you want to do. You are encouraged to discuss with the instructor about your plans..

## Wiki page

You need to create a wiki page for your proposed Q21. It should be similar format to the course book chapters but not included the advanced materials.
In your wiki page you need to create 2 examples with solutions similar to the ones in the 20Q textbook.
