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

  2. 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) IP IP IP IP Layer 2/ Modulation Layer 2/ Modulation Layer 2/ Modulation Layer 2/ Modulation Medium Medium Medium Medium IØ Why?

  3. stop 0 1 0 0 1 0 0 1 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 Δt start

  4. 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

  5. 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

  6.
