Internet Ø: Introduction Karen Sollins MIT CSAIL October 12, 2006

Sollins/I0/ Why? Consider: –Lighting –Air temp and flow –Power mgmt –Access control –Elevators –Sensors/embedded devices Objectives –Extremely inexpensive –Extremely small –Low communication footprint: slow and low volume –Direct peer communication (where possible) Layer 2/ Modulation Medium IP Layer 2/ Modulation Medium IP Layer 2/ Modulation Medium IP Layer 2/ Modulation Medium IP IØ

Sollins/I0/ Design: Criteria and Encoding Medium independence Collision/reflection avoidance: bit length longer than net Simplicity End-to-end modulation UDP, TCP IP SLIP ASCII 8N1 startstop ΔtΔt

Sollins/I0/ Application Support THTP –Single packet payload only –Minimum HTTP support: GET, POST, reply, extremely limited error msgs –Standard HTTP format Scalable encryption: basis for authentication, privacy, integrity

Sollins/I0/ Looking forward Federation: –Multiple Internet Ø nets interconnected: how to allow individual nets retain simplicity –Integrating Internet Ø nets with larger Internet Commercial potential: device, power and control, networking, building industry Services, functionality, support structure between THTP and applications

Sollins/I0/ Documents Internet 0: Inter-device Internetworking, Krikorian, MS Thesis, 2004 The Internet of Things, Gershenfeld, Krikorian, Cohen, Scientific American, Oct SEA: A Scalable Encryption Algorithm for Small Embedded Applications, Standaert, Piret, Gershenfeld, Quisquater, ECRYPT Workshop on RFID and Lightweight Crypto, Graz, Austria, 2005 Design Issues in Internet 0 Federation, Sollins, Li, MIT Dspace Internet Ø: Interdevice Internetworking, Gershenfeld, Cohen, submitted for pub in IEEE Circuits and Devices Mag.
