Radiocrafts AS, a leading supplier of wireless RF modules for communication in the license-free frequency bands, and Sensinode Ltd., a pioneering/commercial supplier of solutions for IPv6 over wireless mesh networks, today launch a new platform for integrating the Internet with sensor networks.
The IEEE 802.15.4 compliant radio modules from Radiocrafts combined with the 6LoWPAN compliant NanoStack from Sensinode offers integrators super compressed IPv6 over low power radios in a very compact module solution. The use of end-to-end open source IP technology over a proven radio platform provides an excellent and scalable solution for IP-based monitoring and control systems like AMI (Advanced Metering Infrastructure) and WSN (Wireless Sensor Networks).
Sun announced that the Sun SPOT project has gone open source. It’s now available at http://spots.dev.java.net. Additionally they announced widespread availability of Sun SPOTs (36 countries and counting) as well as deep discounts for education (see the Sun educational sales rep for details).

Researchers at the Georgia Tech Research Institute (GTRI) have developed a sensor system that continuously monitors the air around persons prone to asthma attacks. Worn in the pockets of a vest, the new system could help researchers understand the causes of asthma attacks.
“We are investigating whether we can go back after an asthma attack and see what was going on environmentally when the attack started,” said Charlene Bayer, a GTRI principal research scientist.

Some real-world battery life results for Arduino projects and XBee mesh networking radios have been published. Use them to help choose which battery setup is right for your project.
All tests have been performed at room temperature with nominally fresh or fully charged batteries. Tests with multiple run times are intended to give a sense of the potential for variance in the results. Results were monitored in a program that keeps track of the first and last time it receives bytes on the serial port.
The results are available here.
Joe Polastre, co-founder and CTO of Sentilla, gave a presentation on Pervasive Computing with Java at the latest Java Mobile & Embedded Developer Days. Sentilla is about making the real world — and everything in it — smarter, with software for small computers that can be put anywhere or attached to anything. Called pervasive computing, this technology is applied in wide-ranging industries such as logistics, transportation, security, health care, agriculture and green technology. Founded in 2003, Sentilla Corporation provides a full life cycle software platform for developing, deploying, integrating and managing pervasive computing applications with the familiarity of Java technology. Sentilla’s mission is to enable the billions of very small computers deployed throughout the physical world to work together to solve really big business problems.

Yesterday at the Java ME developer days Sun announced that the Squawk JVM has been made open source.
For those of you keeping track, this is the JVM used in Sun SPOTs motes.
The code and more info are available on Java.net.
Eric Arseneau, PI of the project gave a talk today at the JME Dev Days conference which you can see here.
We recently got to know about the untimely and tragic death of a fellow sensornets researcher Cormac Duffy. Cormac was working towards his PhD at Univ. College Cork, Ireland and his representative works include “Adding Preemption to TinyOS” (EmNets’07) and “Improving the Energy Efficiency of the MANTIS Kernel” (EWSN’07). He was an extremely lively person and had many friends in the sensornet research community, who are shocked by his death. Cormac died on Aug 17th 2007 in a car accident in Poland. The picture below is from the Dagstuhl Summer School on WSN. Cormac is on the floor, signing and reading lyrics projected on the roof of a Dagstuhl Castle room in Sep 2005. The lyrics read:
| Imagine there’s no heaven
It’s easy if you try
No hell below us
Above us only sky
Imagine all the people
Living for today…
Imagine there’s no countries
It isn’t hard to do
Nothing to kill or die for
And no religion too
Imagine all the people
Living life in peace…
Rest in peace Cormac, you will be deeply missed by your friends and colleagues in the sensornet research community.
