Towards a Trillion Nodes: Crossbow Sensors

From ReadWriteWeb:

You’ve read a lot of theory about the Internet of Things on this blog, but where are actual use cases (I hear you ask)? Part of the reason there have been few documented use cases is that the Internet of Things has yet to make a splash in the consumer market. I believe it will come to the consumer market soon – but that doesn’t mean there aren’t sophisticated Internet of Things products on the market right now.

Crossbow‘s eKo PRO system of sensors is a case in point. But first, here’s the exciting big picture!

The Buzz about BumbleBee

From Crossbow’s blog:

About a year and a half ago the Samraksh Company introduced a new mote-scale radar. Th e BumbleBee is a coherent, pulsed Doppler radar offering rich information at a strikingly low price (i.e., $100 each as compared to as much as $4,000 to $5,000 each for previous mote-scale radars). The BumbleBee measures radial velocity directly allowing users to determine the sign of the velocity and measure the time structure of relative motion very precisely, even for small motions!

The company suspects that there will be high return from effort focused on conceiving applications for the BumbleBee rada as the difference between applications for the BumbleBee and traditional WSN applications is vast. To stimulate the development of applications that benefit from an understanding of the motion the company announced today that it is sponsoring an Application Idea Contest. Researchers and hobbyists who are willing to share their ideas for utilizing rich motion information, especially within the context of WSNs, with the larger community are encouraged to submit short descriptions of their ideas. Two outside judges will select winning ideas, and each winner will receive a free BumbleBee radar! In addition community members will be asked to provide feedback on winning ideas. It is hoped that this feedback will further facilitate creativity.

Environmental Sensing – eKo Style

From Crossbow’s blog:

This past month, Crossbow displayed the award-winning eKo system at the AGU Fall Meeting in San Francisco. The American Geophysical Union (AGU) is a group of members consisting mainly of Earth and space scientists who study how rocks, water, air, space, and life interact with each other to understand how the global system works. What they learn increases our sense of wonder, encourages us to ask new questions, and allows us to make wise use of Earth’s many resources. This particular event draws upwards of 16,000 geophysicists from all around the world who meet to review the latest issues affecting the Earth, the planets and their environments. The eKo system provides a key new alternative by which scientists and researchers can gather data from their environment with an ease and efficiency previously unavailable. The event provided a wonderful venue to meet customers, inspire new ideas and most importantly educate others in the use of wireless sensor networks.

Plug & Play Environmental Sensor Nets


Crossbow Technology, a leading supplier of wireless sensor technology, announced the release of an Environmental Sensor Bus development platform. The plug-and-play architecture hooks to a wide range of sensors with ease analogous to USB, says the company.

The ESB capability allows users to quickly and effortlessly customize the rugged system by integrating smart and custom sensors for their own applications whether it be groundwater contamination or wildfire monitoring.

“Scientists at UMass Boston Center for Coastal Environmental Sensing Networks (CESN) have been researching the development of ’smart’ sensor networks for observing interactions of coastal systems around Boston Harbor. According to Francesco Peri, Managing Director of CESN, “the eKo real-time system is an ideal platform to bridge the land-water sensor network barrier and is helping us to detect hot spots and hot moments.”

In a BLIP, pervasive IP has arrived

From Crossbow’s blog:

Back in March some researchers at UC Berkeley released an Open Source implementation of IPv6 running on TinyOS 2.x called BLIP (Berkeley Low-power Internet Protocol). BLIP is a work in progress.  It is currently fully supported on the TelosB platform and works on MICAz when compiled in a memory-constrained mode.  It is being folded into the TinyOS 2.x core with a slated release date of late August 2009.  The version in contrib/berkeley/blip is the correct one to use, however, as that one will actually build without manually adding radio stack modifications that are still being negotiated.  IRIS support is in the works as well with the initial port being done by European researchers Miklos Maroti and Lars Schor.  An improved release candidate of BLIP is slated to be pushed into contrib as early as next week.

eKo network at NRS reserves pioneer new ways to observe Earth!

From Crossbow’s blog:

Crossbow’s revolutionary eKo system was featured in the Spring/Summer Edition of Transect. The main article focuses on the implementation of sensor networks for observation. The eKo system is being used to monitor the microclimates of the various wetlands at the Blue Oak Ranch Reserve. The goal of the deployment is to collect detailed and accurate measurements about the environment to track changes, but also determine how these changes affect the plant life and various species within that ecosystem.

Using various soil moisturesensors and ambient temperature/humidity sensors with the eKo node, researchers are able to gather valuable data quickly and easily. With its ecofriendly solar-panel and weatherproof enclosure, the eKo system takes technology into the wild! Using the advancements in networking technology, engineers and scientists working at the University of California, NRS reserves are playing a key role in the global discovery occurring through monitoring. The “Alpha Node” tower at Blue Oak Ranch provides information about data above ground and underground. AsHamilton states“It’s a solar-powered weather station, but it’s also a wireless relay point that links the Lick Observatory [owned and operated by UC and located on nearby Mt. Hamilton*] to a directional Wi-Fi radio that points down to the barn, providing us with Internet access. And this omni-directional antenna plugs into the router on the tower to create a large Wi-Fi cloud on the top of the hill that’s strong enough to get a signal down to the pond and the stream at the foot of the hill, so researchers will be able to monitor these locations using portable wireless environmental sensing systems.”

BAIA Panel Wireless Sensor Networks

BAIA, Business Association Italy America, has organized a Panel has organized a Panel on “Business Models and Applications of Wireless Sensor Networks” on 10/08/2008. The event, sponsored by Pirelli Tyre, Telecom Italia and C’ Era una Volta, has taken place at the University of California at Berkeley with more than one hundred attendees from the academia and the industry. The Panel has been kindly introduced by Consul General of Italy in San Francisco Dott. Fabrizio Marcelli.

The distinguished panelists have been:
– Prof. David Culler, UC Berkeley, CTO and Co-Founder of Arch Rock
– Mike Horton, CEO and Co-Founder of Crossbow
– Prof. Raju Pandey, UC Davis, CTO and Co-Founder of Synapsense
– Prof. Kris Pister, UC Berkeley, CTO and Co-Founder of Dust Networks
– Dr. Joe Polastre, CTO and Co-Founder of Sentilla

The panel has been moderated by Prof. Alberto Sangiovanni-Vincentelli, Professor at UC Berkeley, Co-Founder of Cadence Design Systems and Honorary Chairman of BAIA. The Panelists have discussed possible business models for WSNs and have answered the questions of the audience on the market perspectives for the technology and on the obstacles still to be overcome.
