Presentation Transcript

  1. IEEE SECON 2004 Andres Lagar Cavilla

  2. Sensor and Ad Hoc Communications and Networks • First edition • IEEE Communications Society • 4-7 October 2004 • Santa Clara, California

  3. Miscellaneous Stats • 68/358 papers accepted (~19%) • Two keynote speeches • Four Panels • Four Tutorials

  4. Overall Impresions • The Industry is hyping about this • Sensor nets preferred over Ad hoc nets • More tangible right now • But the Industry is also waiting

  5. The Killer Application • A panacea? • Everybody is looking for it. No one is risking anything • Most of the funding comes from the military • No clear guidelines

  6. The chicken & egg problem • Standards to support the development of applications are missing • Applications to propel (and steer) the development of standards are missing

  7. However… • Some startups are taking the first strides • Crossbow • Sensoria • PacketHop • Many industry envoys wre “probing” the field during the conference • Exponential growth in investment predicted

  8. Three things to think about at home • 802.15.4 • IEEE standard to integrate multiple radio interfaces in a network • ZigBee • An industry alliance, equivalent to WiFi for sensor networks and 802.15.4 • Ultra Wide Band • No spectrum constraints • Quasi-unlimited propagation

  9. A National Sensor Network • John Strand, Oak Ridge National Labs • A review of what US army has been doing on sensor networks • Total Installation Awareness • Scary!!!! • But they claim to have it working

  10. Enabling Integration Solutions Commercial Wireless Sensor Networks • Mike Horton, Crossbow Tech • First field for deployment of sensor nets will be on monitoring tasks • Last field will be ubiquitous computing • Enabling technology is already here • Integrating standards in order to provide solutions are missing • Everything Crossbow does is Open Source

  11. Greatest technological challenges in deploying MANETS • Multi network roaming • Cross layer design between L2/L3 • Support for hybrid networking interfaces • Integration of Internet gateways • MANETs are hardly self-managing • PacketHop people insisted on this • Lack of service discovery

  12. Mesh networks • Provide community broadband access • Multihop routing • Nodes are neither mobile nor resource constrained • Lots of impulse from Microsoft, via Viktor Bahl • Skepticism from pretty much everyone else

  13. Paper session: Applications • Controlled Mobility for Sustainable Wireless Sensor Netorks • Controlled mobility enhancing sensor network coverage in the wild • eBlocks – Electronic Blocks for Basic Sensor-Based Systems • Educational: students would try to assemble systems from basic blocks • Analysis of the performance of IEEE 802.15.4 for Medical Sensor Body Area Netowrking

  14. Other interesting papers • The Limits of Localization Using Signal Strength: A Comparative Study • A review of localization algorithms, concluding they’re all pretty much the same • ATEMU: A Fine-Grained Sensor Network Simulator • A HUGE Mica Mote simulator at the CPU instruction level
