SNEE for Sensor NEtwork Engine

The SNEEql (SNEE for Sensor NEtwork Engine) query optimizer, developed at the University of Manchester, is a novel query optimizer for sensor networks which combines a rich, expressive query language with a software architecture based traditional distributed query processing techniques. The optimization steps cover all the query optimization phases that are required to map a declarative query to executable code.

Ixent Galpin will be presenting the query optimization architecture at the International Conference on Data Engineering ’08, in Cancún, Mexco on 10 April 2008. If you are unable to attend the presentation, or are interested in knowing more details, you can view the information on this website.

Wireless sensor networks over IPv6

Radiocrafts, a supplier of wireless RF modules for communication in the licence-free frequency bands, and Sensinode, a supplier of solutions for IPv6 over wireless mesh networks, have launched 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 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).

The Sensinode NanoStack meets the 6LoWPAN (IPv6 over Low power WPAN) specifications released in 2007 and offers a scalable and robust architecture for a wireless mesh network where all nodes cooperate to transport information almost like the Internet. By using many small radio modems, a low-power wireless network can cover large geographical areas using the licence-free frequency band at 2,45 GHz. The self-configuring and self-healing properties of the 6LoWPAN network offer redundancy and low maintenance cost.

Heated up about your Energy Bill? Motes to the Rescue!

From Crossbow’s blog:

When I opened up my Gas and Electric bill from our local utility (PG&E here in Northern California) I was shocked: it was over $100 more than I expected. Some further checking confirmed that it was also substantially higher than during the same time last year, by about that amount. So what happened? Sure, energy prices likely have increased since last year and maybe it was a bit colder here the last month. But it still didn’t add up…

A few years ago I had installed a shiny new programmable digital thermostat to replace an old mechanical gizmo that must have been around since the house was built in the 1950s. And I actually did read the manual (well, some of it anyways) and spent quite a bit of time programming it with different cycles for days and nights and weekends and so on. And, though I was very proud of that accomplishment at the time, the promised energy savings that I had hoped for actually never really materialized. My utility bills stayed pretty much the same before and after the thermostat installation.

Read how, using a WSN, the author was able to gather a lot of valuable data and hopefully significantly reduce his heating bill here.

Yet more open source – the Sun SPOT itself!

The main Sun SPOT hardware itself is now available on

You can find it here. At this point all major parts of the Sun SPOT project are open source – hardware, operating system/virtual machine, drivers and libraries, applications, documentation… its all there. It’s all part of the project’s open source which you can find here.

Re-Mote Testbed Framework

We are happy to announce the first public release of the Re-Mote Testbed Framework featuring code developed in collaboration between DIKU and CIT. The Re-Mote Testbed Framework is a collection of modules for providing remote access to wireless sensor network testbeds. It includes a Java-based GUI client featuring real-time mote interaction using console windows and server-side software consisting of a MySQL database, mote control server, and mote host software.

The major contribution of this release is support for MicaZ and TMote Sky in addition to the original dig528-2 platform. It has
been successfully tested with the two widely used operating systems for WSN: TinyOS and Contiki. To get more information on
the Re-Mote Testbed Framework and the current release, please visit the project development website.

CfP Int. Workshop on Cyber-Physical Systems Challenges and Applications (CPS-CA'08)

The CPS-CA’08 workshop will be held 11/JUN/2008 in Santorini Island (Greece), in conjunction with the 4th IEEE International Conference on Distributed Computing in Sensor Systems (DCOSS’08)

Although the IT transformation in the 20th century appeared revolutionary, a bigger change is probably yet to come. The term Cyber-Physical Systems (CPS) has come to describe the research and technological effort that will ultimately efficiently allow interlinking the real world physical objects and cyberspace. Actually, a few other terms have been used to describe similar endeavors. The term “Internet of Things”, originally aiming at RFID technologies, is smoothly becoming synonymous for cyber-physical systems. The integration of physical processes and computing is not new. Embedded systems have been in place since a long time to denote systems that combine physical processes with computing. The revolution will come from massively networking embedded computing devices which will allow instrumenting the physical world with pervasive networks of sensor-rich, embedded computation.


CfP RTN'08

The 7th International Workshop on Real-Time Networks (RTN’08) is a satellite workshop to the 20th Euromicro Conference on Real-Time Systems (ECRTS’08), both to be held in the beautiful city of Prague, Czech Republic, during the first week of July.

ECRTS is one of the most important conferences in real-time and embedded computing systems. RTN is a very interactive and informal one day workshop, leading to very active, fruitful, hot and polemic discussions among both young and experienced researchers in the fields of real-time, reliable, pervasive and interoperable communication networks. This year’s edition of RTN will particularly focus on “Wireless Sensor Networks and Applications”.

Submission deadline: 21 April 2008
