1. What is a mote? A mote network? A mote fabric?

© 1980 (tending to 1990) PC providing cloud experience

running on two AA batteries for 5 years

platform for next generation of computing

2. What are central challenges for this class of computing?

low cost, low power yet accurate

manageability, programmability, deployability at scale

What is this course about?

3

What are the research themes this quarter?

Node and network energy efficiency In MAC In new mote hardware (scaling down) architectures In hybrid mote-smartphone (scaling up) architectures

Network architecture App centricity (vertical standards) vs. horizontal standards How can a WSN handle app centricity

- can 2 MACs coexist? can 2 networks exist? on the same node?

 

Physical layer exploitation Smarter physical layers can deal better with interference and

security, but can motes be SDRs?

Themes of this course

• Delay tolerance Especially when connectivity is scarce Mobility increases capacity, at the cost of delay What happens to capacity when delay is constrained What happens to exploitation when mobility is predictable

• Sensing complex things in complex environments Machine learning In the field calibration

 • Applications

Control apps for energy conservation Safe apps for energy conservation
