We would like to announce the release of the SNEE sensor network query compiler/optimizer. SNEE (for Sensor NEtwork Engine) has been developed at the University of Manchester. It supports an expressive continuous, declarative query language over acquisitional streams, called SNEEql, using a software architecture that extends traditional distributed query processing techniques.
SNEEql queries are compiled into query evaluation plans (QEPs) in the form of executable nesC/TinyOS code. SNEEql QEPs currently target the TOSSIM simulator and the Avrora Mica2/MicaZ instruction-level simulator (TinyOS 1.x only). We have also run SNEE-generated QEPs on Tmote Sky motes running TinyOS 2.x, and a further release in which the generated QEPs are fit for small-scale experiments on such mote-level hardware is planned for the next few months.
The source code of SNEE has been released under the New BSD License, and is hosted at:

Libelium has released a new application to send data collected by its sensor network to Twitter and WordPress. The final idea is to make things and the environment “talk” and have its own space in the web updated in real time.
A forest or city with its own blog updated by itself?, a house which can twitter in real time? Yes! it is possible, and it is open source. The application works with the Waspmote sensor platform collecting the information and the Meshlium router as a bridge between the 802.15.4/ZigBee network and the Internet.

Andy Rubin, father of Google’s Android operating system, waxed ecstatic about the future of mobile computing in a blog post Sept. 19.
Noting that there are roughly 3.2 billion mobile gadget subscribers in the world, Rubin said sensors in our phones power clocks, thermometers, accelerometers and even compasses. Other sensors calculate user location and gauge battery power.
Sensors will be ubiquitous, as Rubin wrote:
Your phone knows a lot about the world around you. If you take that intelligence and combine it in the cloud with that of every other phone, we have an incredible snapshot of what is going on in the world right now. Weather updates can be based on not hundreds of sensors, but hundreds of millions. Traffic reports can be based not on helicopters and road sensors, but on the density, speed, and direction of the phones (and people) stuck in the traffic jams.
Our phones will be smart about our situation and alert us when something needs our attention. While we currently get news alerts or notifications when tickets go on sale, mobile Web apps will monitor our personalized preferences in the Internet cloud and tailor information updates to us.

From Wired Science:
To gamers, $40 may seem like a steep price to replace a Wii remote controller, but to scientists, a hacked Wiimote is a steal compared to the pricey sensors needed for a lot of field research.
Inspired by videos of renowned hacker Johnny Chung Lee turning the Wiimote into a finger-tracking device and a touchscreen white board, physicist Rolf Hut of of Delft University of Technology built a Wiimote wind sensor.
“It was just a bendy pole with an empty bottle on top with an LED light on the bottle,” Hut said. “And it swayed in the wind.”
The Wiimote can track just about anything: All that’s needed is an LED light. Hydrologist William Luxemburg of Delft University of Technology in the Netherlands demonstrated a hacked water-level sensor made from a Wiimote and a plastic boat at the meeting of the American Geophysical Union here Monday.

CitiSense, a cell-phone based sensor network system, has won a $1.5 million grant from the National Science Foundation to develop and deploy hundreds of small environmental sensors carried by the public in San Diego.
The goal of CitiSense is to build and deploy thousands of small environmental sensors that use cell phones to relay data. The sensor-wearing public may also wear biological monitors, collecting basic health information, such as heart rate. The data will be analyzed, anonymized and reflected back out to individuals, public health agencies and San Diego at large.
“San Diego County has 3.1 million residents, 4,000 square miles, and only five official EPA air quality monitors. Our goal is to give San Diegans up-to-the-minute environmental information about where they live, work and play —information that will empower anyone in the community to make healthier choices,” said William Griswold, the principal investigator on the grant.

At UC Berkeley, PATH Research Program investigate technologies that would allow cars, buses and trucks to connect with the roadway using sensors placed on vehicles and magnets drilled into the cement. Researcher Wei-Bin Zhang believes the technology could prevent accidents and reduce pollution in the atmosphere with less human interaction in the driving process.
2009 has been a turning point for the Internet of Things, when real world objects (such as lights, cars and packages) get connected to the Internet. This trend has added a significant amount of new data to the Web, so for that reason alone it is an important development. Having said that, many of the following top 10 list are not yet mainstream products. But we expect some of them to become well known over the coming years.
The list of top 10 Internet of Things Products of 2009 is here.
The companion lecture slides for 6LoWPAN: The Wireless Embedded Internet have now been released on The Book page of 6lowpan.net. This first part of the book’s course material includes a suggested course syllabus, and 115 of lecture slides in both PowerPoint and PDF formats. This overview of the book is a good tool for lecturers, students and professionals alike. The slides have been released under a creative commons by-nc-sa license to encourage re-use. The companion exercise slides for Contiki are planned for release in the near future.

Just one week after the release, the Waspmote sensor platform will be shown in two public presentations during the month of December.
Libelium will show among other things how the Gas Sensor
Board can measure in real time small variations of Oxygen and CO2 in order to detect a fire, how to use the Events Sensor Board to detect water flooding or which sensors use to detect presence of people for security applications. The dates: Barcelona 15th December, Madrid 17th December. Contact Libelium for more info.
Sensors Magazine recently published the article “RF Energy Harvesting Enables Wireless Sensor Networks” by Harry Ostaffe of Powercast. The article is a brief introduction to RF energy harvesting: what it is, what it does, and how it enables wireless sensor networking applications.
