From Moteiv’s blog:
The Mobile & Embedded System research group at Yonsei University has released a new operating system for wireless sensors networks called “RETOS”, Resilient, Extensible, and Threaded OS for Wireless Sensor Networks. Information about the operating system was published at this year’s IPSN/SPOTS conference, where I was a member of the program committee. The initial release supports Moteiv’s Tmote Sky modules.
RETOS is a departure from the standard TinyOS framework that many know and love. It supports dynamically loadable modules (ala SOS from UCLA) and a multithreaded system allowing programmers to block on events instead of building complex state machines for asynchronous code.
Researchers from Imperial College London are developing miniature computers that could enable detailed and quantitative analysis of our fitness and health.
“Imagine computers as small as a pin head, but with enough power to carry out information processing, and affordable enough to be disposable,” says Professor Guang-Zhong Yang from Imperial College London. “As these inexpensive, flexible and customisable devices get more and more common, the computers themselves will gradually “disappear” into the fabric of our lives.”

Municipalities worldwide are adopting Wireless Sensor Network (WSN) technology to make their cities safer, healthier, greener, and more productive, according to a recent research study by ON World.
WSN solutions for Smart Cities are being driven by increased spending on wireless broadband infrastructure, standards such as IEEE802.15.4 and ZigBee, increasing Green regulations, and the ongoing need for improved public safety
Commercial WSN solutions for transportation, public safety, and municipal services are currently deployed in cities such as San Francisco, Oakland, Chicago, Los Angeles, and Songo, South Korea. From several recent surveys with 220 North American municipalities and public safety organizations, ON World found that cities are highly motivated to adopt WSN over the next 18-24 months for transportation, public safety, utility networks, and energy management.

Now even the turtle is addicted to wireless technologies. Using a solar-powered GPS and WiFi, University of Massachusetts researchers have created TurtleNet: the world’s first all-turtle network.
Used to track movement patterns of endangered snapping turtles, TurtleNet relies upon periodic turtle-to-turtle WiFi relays as turtles pass other turtles. Then, when one of these turtles comes close to the UM base station, all turtle data is uploaded and sent to the lab 15 miles away. We just think it’s sick that researchers have burdened an endangered species just for some free WiFi in the middle of the swamp. It’s not even hooked to the internet, stupids!

A recent ON WORLD report “WSN for Smart Buildings” declares this technology’s clean and inexpensive system deployments will result in more buildings using less energy, needing less maintenance, and producing lower carbon emissions. It forecasts global revenues for WSN commercial building solutions will be $2.6 billion, by 2011. As well as 25% of commercial building energy reduction attributed to WSN by 2013, worth $7.4 billion in global energy savings.
It calls several emerging market opportunities for WSN such as lighting control systems, metering, and condition monitoring. And other markets such as lodging, manufacturing, warehousing and data centers, which often lack traditional building control systems, seem to have the highest demands for WSN today.
According to the report, IEEE802.15.4 and ZigBee are the winning technologies for WSN solutions in commercial buildings.

The Warsaw University of Technology, Warsaw, Poland, is organizing a Summer School on Applications of Wireless Sensor Networks, from September 10th to the 14th.
The goal of this summer school is to:
– survey the most relevant research domains
– present various perspectives and underlying technologies
– identify the most important challenges and research themes
– interact with distinguished scholars and establish contacts that may lead to research collaborations in the future
The intended audience consists of post-graduate students, PhD students, and young researchers from universities and industrial laboratories around the world.

Quoting Philip Levis, who coordinates the WG efforts:
“..Historically, the WG list has been closed only to members, with non-members being able to read the archives online. A few weeks ago, the WG decided that it would be better if most technical discussions occurred in a public forum. We decided that this would be an excellent use of tinyos-devel. The private WG list still exists, but we plan to use it mostly for administrative issues, such as organizing teleconferences and release management.. ”
As they are starting to package up 2.0.2, there would be a few discussions on some proposed changes for the next release, 2.1. According to the recent peak of activity in the tinyos-devel list, currently active developers are planning to include a new version of the Python stack developed by Matt Welsh and his group at Hardvard, which will permit to migrate all PC-side tools to Python.
Among other interesting contributions, there is a new implementation of the serial forwarder for T2 in C++, by Andreas Koepke from TU Berlin, which may also be included. Been more reliable and showing higher throuput, the new code it’s tailored to run on the ARM based NSLU2.
