  1. Welcome to CS580S!!! KD Kang

  2. What are sensor networks? • Small, wireless, battery-powered sensors Smart Dust MICA2 mote

  3. Why small, wireless, battery-powered sensors? • Traditional big, wired sensors • Expensive, inefficient, hard to deploy, power-consuming • Undesirable: Deployment of big traditional sensors can disturb the environment, in habitat monitoring • Dangerous: Imagine manual deployment of big traditional sensors for structural monitoring or battlefield monitoring

  4. WSN Applications • Inexpensive micro-sensors & on-board processing • Ad-hoc deployment thanks to wireless communications – No communication infra should be built • In-situ monitoring • Spatially and temporally dense monitoring • Monitor previously unobservablephenomena Seismic Structure response Contaminant Transport Ecosystems, Biocomplexity Marine Microorganisms

  5. Applications Habitat Monitoring Great Duck Island Structural Monitoring Golden Gate Bridge Precision Agriculture Medical Application CodeBlue at Harvard

  6. Hot, exciting area of research • For example, read a NY Times article below http://www.nytimes.com/2004/07/26/business/26sensor.html?ex=1248667200&en=d206d4279ebb633b&ei=5088&partner=rssnyt • Many more articles about WSN applications and expected economic impacts • WSNs work in totally new environments • New computing paradigms required!!!

  7. Course Topics • Hardware & Operating Systems • Programming & Debugging • Medium access control • Routing • Real-time Communication & QoS • Localization • Time synchronization • Query Processing and data aggregation • Security

  8. Grading • Paper critique: 10% • Paper presentation: 20% • Project: 60% • Class Participation: 10% • No exam! No homework!! 

  9. One Page Paper Critique • Part A: Briefly identify the key contributions of the paper • What research problem does it try to solve? • Why is it an important problem? • What's the proposed approach? • Part B: Try to find if there is any problem in the paper • Any problems in the assumptions? • Any technical shortcomings or drawbacks? • Do the experimental results support the original claim? • Part C: Any idea for improvement? (Optional) • Most challenging part • You can get the full credit by finishing Parts A and B • But, you are encouraged to try do this part as well

  10. Paper Presentation • 25 minute presentation • Present key ideas & performance results • Discuss related work to show how the paper presented by you is different from other work • 5 minutes for questions & discussions

  11. Project • Max 2 students can work as a team • Find your team! • “Try” to find a new idea • Your final results may not be novel, but that’s OK • If it’s novel, it’s even better • Example: • Implement and compare 2-3 existing routing or data aggregation protocols • Implement a localization protocol and inject attacks: Observe what happens & discuss possible countermeasures • Implement an existing packet scheduling algorithm and tweak it to improve the performance • Use your imagination! 

  12. Next Class • Read “Overview of Sensor Networks” in the Reading List (http://www.cs.binghamton.edu/~kang/teaching/cs580s/) • No critique required for this paper
