Overview

Sensor History • Early 1980s

– DARPA started the DSN program – Arpanet had 200 hosts – Mobile nodes were carried by trucks

• 21st Century

– DARPA funded SensIT program – Internet tomography is a research field per-se – SmartDust sensors fit into 1 mm3

Overview

Sensor Keywords • Sensor Hardware

– Cheap, publicly-available, off-the-shelf components, modular, integrated, powerefficient, extensible, tiny

• Sensor Software

– Free, open-source, modular, abstract, powerefficient, extensible, small

• Keywords are very similar

– This follows from high level of integration
