Transcript

  • 1. Helpful Technology and the Internet Of Things Robert Poor <r@robertpoor.com> NBT Group 14 June 2005 NOST Spring 2005
  • 2. Smart versus Helpful • smart: CLEVER “mentally quick and resourceful but often lacking in depth and soundness” • helpful: USEFUL “serviceable for an end or purpose” 14 June 2005 NOST Spring 2005
  • 3. Helpful Technology • Connectivity is more important than local processing power. • Embedded Wireless Networking – Cost – Technology – Standards • Commercial Results • Areas for further research 14 June 2005 NOST Spring 2005
  • 4. Bob Lucky’s Hierarchy Wisdom Knowledge Information Data Signal 14 June 2005 NOST Spring 2005
  • 5. The Internet Of Things 150M “The overarching promise CPUs driving [low rate, low power wireless systems] is low cost, self-installing wireless technology that links devices, systems and 7.5B embedded human operators and runs microcontrollers ostensibly on common batteries for months or even years.” [WDRG 2003] Units manufactured in 2001 (projected) Source: DARPA / Tennenhouse 2000 14 June 2005 NOST Spring 2005
  • 6. Wireless Embedded Networking • Moore’s Law: The cost of silicon-based systems decreases exponentially with time. • Result: Wireless Embedded Networks will continue to become cheaper due to reduced silicon costs. • Metcalfe’s Law: The value of connecting to a network increases as the square of the number of connections. • Result: Wireless Embedded Networks will continue to become more valuable as they grow. 14 June 2005 NOST Spring 2005
  • 7. Vanishing Cost of Processing Cost of Computing: $/MIPS $1,000,000,000.00 $100,000,000.00 10x reduction every 7.5 years $10,000,000.00 (2x reduction every 27 months) $1,000,000.00 $100,000.00 $10,000.00 $1,000.00 $100.00 $10.00 $1.00 10x reduction every 4 years $0.10 (2x reduction every 15 months) $0.01 1959 1964 1969 1974 1979 1984 1989 1994 1999 2004 2009 Source: Hans P Moravec, http://www.frc.ri.cmu.edu/~hpm 14 June 2005 NOST Spring 2005
  • 8. Mesh Technology A 95% B 40% 95% C Star Architecture: 40% reliable at node B In a Star Architecture, link reliability is limited by SNR between each node and its Access Point. 14 June 2005 NOST Spring 2005
  • 9. Mesh Technology A 95% 95% B 40% 95% C Mesh Architecture: 94% reliable at node B In a Mesh Architecture, nodes cooperatively route messages, resulting in increased reliability. 14 June 2005 NOST Spring 2005
  • 10. Mesh Technology A 95% 95% B 40% 95% 95% C Mesh Architecture: 99.4% reliable at node B In a Mesh Architecture, nodes cooperatively route messages, resulting in increased reliability. 14 June 2005 NOST Spring 2005
  • 11. Standards • IEEE 802.15.4: low-rate (250 Kbits/sec), 2.4GHz DSSS. Multiply sourced (Chipcon, Ember, FreeScale, others). • ZigBee: Defines compatible profiles on top of 802.15.4 for specific applications. Over 150 member companies. See www.zigbee.org. • WINA: Wireless Industrial Network Alliance. Best practices for Industrial Applications. See www.wina.org. 14 June 2005 NOST Spring 2005
  • 12. Some Commercial Products Philips Lighting: Wireless Lighting Control Nuri Telecom: AIMIR Automatic Meter Reading Eaton Corporation: Home Heartbeat Home Awareness Raymarine: S1000 Wireless Autopilot System 14 June 2005 NOST Spring 2005
  • 13. Selected Research Topics • Alternative power sources, including energy scavenger systems. • Ranging Systems based on Ultra- WideBand (UWB) and other technologies • Smart Radio and efficient spectrum usage. • High-level software interfaces: connecting to the Enterprise • June 2005 is the “TCP/IP” 2005 the Internet Of 14 What NOST Spring for Things?
  • 14. Thank you. Questions? Robert Poor <r@robertpoor.com> 14 June 2005 NOST Spring 2005
