Networked Systems Practicum Lecture 1 – Introduction 1

Today’s Lecture Administrivia Topics and Overview 2

Instructors Instructors. Srini Seshan 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 Handouts, readings,.. Piazza for Q&A Office hours by appointment Course secretary Angela Miller, Gates

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! 10
