  1. 15-446 Networked Systems Practicum Lecture 1 – Introduction

  2. Today’s Lecture • Administrivia • Topics and Overview

  3. Instructors • Instructors. • Srini Seshan • srini@cs.cmu.edu, Gates Hall 8123 • Teaching assistants. • None (a couple informal ones )

  4. 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

  5. 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

  6. 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

  7. 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

  8. 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!

  9. 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

  10. 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!

  11. Today’s Lecture • Administrivia • Topics and Overview

  12. Other Topics • Supporting capstone projects • Lectures topics will be added/changed to match project topics and student interests • Email me topics you want to learn about 

  13. 3 Sections • Mobile Networking • Networking/Mobile Security • Mobile Systems

  14. Mobile Networks • Wireless Networks • 802.11 • Bluetooth • Mobile IP • Wireless + TCP • Cellular Networks • 3G/4G standards • Mobility support

  15. Mobile Networks • RFID/NFC • Phy + MAC layer protocols • RFIDs with computation • Scaling RFID protocols • Energy Management • Sleep modes in different technologies • Using Proxies • Protocol interactions with power management

  16. Security • Understanding types of security • Privacy • Confidentiality • Authentication • Internet related issues • DoS/DDoS • Spoofing • Protocol design

  17. Security • Crypto basics • Public/symmetric key crypto • One-way hash functions • Merkel trees • Blind signatures • Identity-based encryption • Privacy • Location privacy • Privacy policies • Mix networks/onion routing • Wireless privacy

  18. Mobile Systems • Energy • Tracking techniques • Sleep modes and energy management • Display energy • Transcoding and Mobile Optimization • Offload and proxies • Automated Web page rewriting • Source content mangagement

  19. Mobile Systems • Sensor networks • Sensor motes • Participatory sensing • Vehicular networks • Network protocols • Applications

  20. Mobile Systems • HCI Issues • Designing applications for mobile devices • Dealing with portability issues • Advertising • Ad networks and APIs • Targeting techniques • Click fraud and overheads

  21. Next Lecture / HW • Possible project topic discussion • Intro to Android programming (part 1) • HW • Download/install SDK (http://developer.android.com/sdk/index.html) • Start with basic hello world exercise (http://developer.android.com/training/basics/firstapp/index.html)
