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

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 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 Standards to support the development of applications are missing Applications to propel (and steer) the development of standards are missing

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

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

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 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 EnablingIntegrationSolutions

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 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 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 for Medical Sensor Body Area Netowrking

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
