7. Fall 2007 09/10 The Focus: TECHNOLOGY!!! How to develop a NEW TECHNOLOGY! –Innovation: being FIRST to do it NOT necessarily the best solution so far –WHY and HOW to do things? NOT knowledge learning as the TOP GOAL –Concept NOT the math, formula, or dirty details –The US way to invent a technology NOT the Asian or even European way to improve technology

8. Fall 2007 09/10 The Course Description No required textbook for this course, only a set of “classic” and recent papers Read and discuss –your class participation counts practice what you have learned –do a term project –make your contributions Medium workload expected –You are expected to be prepared for each lecture from NEXT WEEK by reading one paper BEFORE coming to the class

9. Fall 2007 09/10 Prerequisites basic knowledge of packet switched networks & familiarity with TCP/IP protocol suite adequate programming experience –familiar with C/C++/UNIX –Familiarity with ns-2/QualNet is a plus –useful reference books: “TCP/IP Illustrated, Vol’s 1 & 2” by Stevens

10. Fall 2007 09/10 Course Workload One midterm, one final exam Reading homework: –Provide answers for each paper: 3 strong points 1 weak point 1 suggested improvement (optional) –Answer a few questions for each paper Available on the course homepage –(Optional) Critique of the work from Intellectual context, Industry context, Personal context –Be critical!!! all assignments before lecture on the due date –No electronic submissions! Only paper copies

11. Fall 2007 09/10 More on Reading Homework At least 4 items of 3 strong points: 3 most important things stated by the paper –Could be combination of motivations, observations, interesting designs, or clever implementations (1) from the author’s perspective at the time; (2) your perspective with the benefit of hindsight One weakness: what is the single most glaring deficiency? –Design flaws, poorly designed experiments, narrow-scoped main idea, weak applicability, …

12. Fall 2007 09/10 More on homework One key assumption/observation that led to the research –What were the key observations? –Where did the observation/assumption come from? Personal experience, or work environment, … One key risk/obstacle –What are they to prevent the research from successful? –Were the authors aware of them? Are these obstacles eventually overcome?

13. Fall 2007 09/10 Course Project 1 project: Campus Sensor Network Design –2 sub-areas: (1) Application design; (2) Networking protocols or systems aspect –4 persons on each topic No programming is required, design only –Focus on formulating the problem, identifying new issues, coming up with solutions, laying out the evaluation plans Pick a topic and a team by this Thursday Proposal + Checkpoint + Presentation (or report)

14. Fall 2007 09/10 Grading Policy Grading breakdown: midterm exam: 20% Final exam: 25% homework assignments: 30% –There would be 12 home assignments –You can submit 8 out of 12 term project: 25% –Applications: 10% Report 10% –Systems 15% checkpoint report 5%, presentation (or final report) 10%
