The Weightless SIG announced the publication of version 1.0 of the new Weightless-N open standard based on a low power wide area star network architecture. Operating in sub-GHz spectrum using ultra narrow band (UNB) technology, Weightless-N offers best in class signal propagation characteristics leading to excellent range of several kilometres even in challenging urban environments. Very low power consumption provides for exceptionally long battery life measured in years from small conventional cells and leading edge innovation in design minimises both terminal hardware and network costs.
Central to the Weightless proposition is its status as an open standard. Weightless is differentiated from all alternative proprietary LPWAN technologies by uniquely enabling a competitive, free and fair market that does not lock developers into using particular vendors or network service providers.
Details of hardware supporting Weightless-N as well as SDKs will be made available on the Weightless website shortly.

WSNWARE is an open source Java/OSGi middleware, designed for monitoring, controlling and standardizing Wireless Sensor Network.
WSNWARE is a normalized message oriented middleware, messages are transformed by incoming/outgoing adapters, which are specific to the application (as RAW packet is).
WSNWARE aims to provide a standardized access and representation of the network, its nodes and equipment (i.e. sensors). It comes with a set of tools and components which enable rapid development (i.e. create GUI, applets, web services, REST services) and easily bind to new modules.
The OSGI framework has been selected as container for WSNWARE modules, although the library and most of the components are designed as POJO and may be easily integrate in standalone (non-OSGI) contexts.
WSNWARE provides a set of bundles which can be used by developers for developing high-level WSN applications in RAD style, improved by OSGi modularization and management.
Ready-to-use platform adapters and real-world samples, are provided as well:
- TinyOS2, Java.comm RXTX and their examples,
- high level filters (statistical, noise-channel),
- GUI expositors (real-time tables, charting),
- GUI controllers and a dynamic IDE,
- Multilateration application example

TRMSim-WSN (Trust and Reputation Models Simulator for Wireless Sensor Networks) is a Java-based simulator aimed to test Trust and Reputation models for WSNs.
It provides several Trust and Reputation models and new ones can be easily added.It allows researchers to test and compare their trust and reputation models against a wide range of WSNs. They can decide whether they want static or dynamic networks, the percentage of fraudulent nodes, the percentage of nodes acting as clients or servers, etc.It has been designed to easily adapt and integrate a new model within the simulator. Only a few classes have to be implementend in order to carry out this task.

3rd ACM Workshop On Embedded Sensing
Systems For Energy-Efficiency In Buildings
Seattle, WA, USA
November 1, 2011
Co-located with ACM SenSys 2011
The World is increasingly experiencing a strong need for energy consumption reduction and a need for efficient use of scarce natural resources. Official studies report that buildings account for the largest portion of World’s energy expenditure and have the fastest growth rate. Wireless sensor networks (WSNs) play a key role in enabling energy-saving systems in buildings and surrounding spaces by providing a reliable, cost-effective and extensible solution that can be placed in existing as well as new structures and can be controlled via the Internet.
* Paper submission deadline: July 30, 2011
* Notification of acceptance: August 31, 2011
* Camera Ready Due: September 15, 2011
* Workshop date: November 1, 2011
*** New this year: Demo session! ***
We solicit both papers AND demos that focus on new techniques and technologies capable of improving the global energy efficiency of buildings leveraging connected sensing systems, networks, and devices. Technical papers will be presented on November 1, 2011, and the demo session will be co-located with ACM SenSys on November 3, 2011.

We are ready to release a new app for the ThingSpeak Platform! The new app is called TweetControl – this app listens to Twitter for hashtags (#awesome) and allows you to control anything that you can imagine. TweetControl is a mash up of ”The Internet of Things” and social networking. We were inspired by an early ioBridge project created by Matt Morey in July 2009 that used Twitter for home automation. Matt could control lights or turn on his furnace using Twitter. Now that Twitter has a Streaming API, we were able to build a scalable service to control anything in real-time via a social network.
Imagine an “Easy Button” for Twitter. All you have to is Tweet a hashtag from your Twitter account to control anything that has a web service API. The applications for TweetControl are endless, and we are excited to see what you come up with. The documentation for TweetControl is available on the ThingSpeak Community site to help you get started.
