Projects:

The projects will involve the design and implementation of networking protocols and/or application. Students are expected to employ the theories and techniques learned in the class to design the system. Network simulation environments, such as NS-2, may be used in implementing the projects.

Details of the projects will be later made available at Assignments & Projects.

Tests:

Both analytic and synthetic abilities are emphasized. Being able to apply the learned knowledge toward problem solving is also highly emphasized in the tests.

Assignments and Late Penalty:

Assignments and projects will be posted at the class web site. Assignments & projects are due before the beginning of the class on the due day. See Topics and Notes for the due dates.

Points will be deducted from late assignments: 20% for the first 24 hours after the due time, 40% for the next 24 hours, 70% for the third 24 hours, and 100% after that. No extension will be granted except for documented emergency. Starting to work on the assignments as early as possible is always the best strategy.
NOTE: Unless otherwise specified, all assignments and projects are individual work. Students should take caution not to violate the academic honesty policies. See http://b3308-adm.cl.uh.edu/PolicyProcedures/Policy.html for details.

Assignments Guidelines:

a. Identification page: All assignments must have your name, and course name/number/section number (e.g., CSCI5931-01) at the top of the first page.

b. Proper stapling: Staple all the pages together at the top-left corner. NOTE: Do not use paper clips.

c. Order ! Order! Arrange the solutions following the sequence of the questions. Write the question number at the top-right corner of each page.

d. Word processing: It is required that you type your reports (e.g., print them using a printer). Use a word processor and appropriate typesetting and drawing tools to do the assignments. Spell-check the whole document before printing it. You may loose points due to spelling or grammatical errors.

Attendance Policy:

You are expected to attend all classes. If you ever miss a class, it is your responsibility to get hold of whatever may have been discussed in the class.

Instructor's Notes:

Unless due to unexpected, documented emergency, no make-up exams will be given. No make-up exams will be granted once the exams have been corrected and returned to the class.

Important: If you think you have lost some points due to grading errors, make sure you approach the instructor within a week after the assignment, project, or test is returned to you.

To get the most out of this class, you need to read the textbooks and spend time using computers regularly. Be prepared for a class by preview the material to be covered in that class and participate in discussions and problem-solving exercises, if applicable, in the class.

Due to the intensive nature of graduate classes, 15-20 hours per week are expected of students in studying the textbook/notes and working on the assignments, in addition to class attendance. Expect to spend more hours during summer sessions.
