Description:
The goal of this course is to introduce students to the core concepts of wired and wireless networking. The primary focus will be on the layered architecture and the protocol stacks. At the end of the semester, students will well understand several concepts, including the Internet architecture, HTTP, DNS, P2P, Sockets, TCP/IP, BGP, Routing protocols, wireless and sensor networking, WiFi, cellular and satellite networks, and security.
<Here> is the list of topics covered in this course. If time permits, some advanced networking concepts will be discussed.

Prerequisite: Minimum grade of C- in CMSC351 and CMSC330; and permission of CMNS-Computer Science department. Or must be in the (Computer Science (Doctoral), Computer Science (Master's)) program.

Grading:
(1) Final exam (20%) - One closed book/computer exam at the end of the semester covering the entire syllabus.
(2) Midterm exams (30%) - Two closed book/computer in-class exams covering selected topics from the syllabus.
(3) Programming assignments(25%) - Five programming assignments.
(4) Project (20%) - One semester-long project in a group of four students.
(5) Class participation (5%) - Participation in discussions, and asking meaningful questions.
[Note: Bonus points will be capped per section (final exam, midterm exams, assignments, and final project).]
