sensor and ad hoc communications and networks
Sensor and Ad Hoc Communications and Networks
  • First edition
  • IEEE Communications Society
  • 4-7 October 2004
  • Santa Clara, California
miscellaneous stats
Miscellaneous Stats
  • 68/358 papers accepted (~19%)
  • Two keynote speeches
  • Four Panels
  • Four Tutorials
overall impresions
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
the killer application
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
the chicken egg problem
The chicken & egg problem
  • Standards to support the development of applications are missing
  • Applications to propel (and steer) the development of standards are missing
  • 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
three things to think about at home
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
a national sensor network
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
commercial wireless sensor networks




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
greatest technological challenges in deploying manets
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
mesh networks
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
paper session applications
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
other interesting papers
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
