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
