MOTIVATION

Energy efficiency is a major challenge in WSNs

Deploying sensors is hard and expensive

Lifetime is key!

Tanenbaum, A.S.; Chandana Gamage; Crispo, B., "Taking Sensor Networks from the Lab to the Jungle," Computer ,

vol.39, no.8, pp.98,100, Aug. 2006

GOALS

Monitor in a smart, energy-efficient way (nesC)

• Sample rates

• Power states

• Information bundles

Reconstruct the information (MATLAB)

• Interpolation

SOFTWARE

TinyOS

• Free, open source OS targeting WSNs

• Originally a research project at the University of California Berkeley

nesC

• An extension to the C programming language

• Component-based, event-driven programming language

• Programs built from components "wired“ together

• Commands and events pass between components through interfaces
