Lecture 1 – Introduction

1

Today’s Lecture

• Administrivia

• Topics and Overview

2

Instructors

• Instructors.• Srini Seshan

• srini@cs.cmu.edu, Gates Hall 8123

• Teaching assistants.• None (a couple informal ones )

3

Course Goals

• Learn about mobile system design• Wireless networks• Energy management• Split application design

• Learn about security for networked systems• Basic crypto techniques• Privacy challenges in mobile systems• DDoS

• Learn how to build systems that use the network• Capstone project

4

Course Format

• ~20 lectures• Cover the “principles and practice”• Complete readings before lecture• Readings based on recent systems/research papers

• 4 homework assignments• “Paper”: Do you understand and can you apply the material?• “Lab”: learn key system concepts

• Capstone-like project

• Midterm and final• Covers each of the above 3 parts of class

5

Project

• Topic of your choice• Discussion of topics next lecture• Should have something to do with mobile computing

• Regular meetings (approximately 1 per 4 weeks)

• Final handin: code, presentation + demo, short (few page) writeup

• Solo or in groups of 2• Both students should understand the entire project• Expectations of groups will be somewhat higher

6

Administrative Stuff

• Watch the course web page• http://www.cs.cmu.edu/~srini/15-446/F11/• Handouts, readings, ..

• Piazza for Q&A

• Office hours by appointment

• Course secretary• Angela Miller, Gates 9118

7

Grading

• Roughly equal weight in projects and testing• 45% for Project• 15% for Midterm exam• 20% for Final exam • 20% for Homework/Participation

• You MUST demonstrate competence in both projects and tests to pass the course• Fail either and you fail the class!

8

Policy on Collaboration

• Working together is important• Discuss course material in general terms• Work together on program debugging, ..• Final submission must be your own work

• Homeworks, midterm, final

• Web page has details

9

Late Work and Regrading

• Late work will receive a 15% penalty/day• No assignment can be more than 2 days late• No penalty for a limited number of handins - see web

page• Only exception is documented illness and family

emergencies

• No assignments with a “short fuse”• Start on time!
