WSNWARE – Java Middleware for Wireless Sensor Networks

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 & Reputation Models Simulator for Wireless Sensor Networks

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.

TweetControl: Control Anything with Twitter

TweetControl App by ThingSpeak(Reposted from thingspeak.com)

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.

iPhone Radiation Dock Will Help Japan Track Impacts of Nuclear Crisis

Japan is still reeling from the nuclear radiation issues following the record-setting earthquake experienced last month. To help, one collective has come up with an interesting device — a portable Geiger counter that docks with an iPhone. By calling your iPhone, you can listen to the familiar clicks that tell just how much radiation is present in a particular area.

The basic idea behind iGeigie is to attach a Geiger counter to an iPhone so that it can be a tool for citizen scientists to collect information about radiation levels where there currently is no data being collected. 

RTDN.org, “a collective voice helping others stay informed,” is behind the project. It is a website providing an aggregate feed of nuclear radiation data from various sources including government groups, NGOs and citizen scientists. They currently have a Kickstarter campaign going to raise funds for a sensor network.

The basis of the project is that there are still many areas where information about radiation levels is not being collected. The sensor network would fill in those gaps. Devices would be sent out to tech-savvy people who will help collect and submit information so that anyone — from the average Joe to nuclear scientists — can use it to come up with patterns and solutions.

The group is about 1/3 of the way to their $33,000 project goal, and you can help out.

iGeigie is certainly an interesting device to help push this sensor network forward.Dvice has a video of a panel discussion at New Context Conference in Tokyo, where a 5.3 aftershock hit while RDTN co-founder Aaron Huslage explained the merits of the project.

What if buildings could autonomously react to climatic changes?

Intelligent buildings reacting autonomously to temperature variations or precipitation forecasts, car traffic being diverted because ozone concentrations are reaching hazardous levels, or street lighting reacting to the passage of vehicles: these are some of the technological developments that will no longer depend on complex, expensive infrastructures. The EMMON project, led by Critical Software, is developing wireless sensor networks that will enable intelligent and proactive automated responses to data from a wide variety of cheap and reliable sensors.

Last December the EMMON Consortium unveiled the largest wireless sensor network in Europe, demonstrating a functional prototype with no less than 303 tiny sensors in a single room, gathering detailed, real time information on temperature, humidity and ambient light.

“This functional prototype demonstrates the integration of a number of core components, from embedded wireless sensors all the way through to the control station. The prototype, which is the largest single location wireless sensor network in Europe, was integrated and demonstrated at the Instituto Superior de Engenharia do Porto (ISEP), in the CISTER research unit, one of the main scientific partners of the project”, said Délio Almeida, the Project Coordinator from Critical Software.

The EMMON technology has very wide potential, including the ability in the near future to monitor not only the ambient conditions in the vicinity of buildings, bridges and tunnels, but also their very structures. Early warning of their degradation has obvious implications for the avoidance of disasters.

One major advantage of EMMON over existing technologies, such as they are, is that it doesn’t require expensive modifications to the structures being monitored, nor the installation of cabling. It is naturally much cheaper and quicker to upgrade such systems in the future.

The project’s final demonstration is currently being planned, in consultation with a number of organizations whose opinions on the requirements have been valuable. These include CCDR-N (responsible for environmental monitoring in the Northern region of Portugal), Living PlanIT (responsible for Smart City, from Paredes), Living Lab Malta (Malta Smart City), the National Forestry Authority (AFN), Brazil’s National Water Agency (ANA) and the National Civil Protection Association (ANPC).

Pedro Braga, the project’s Technical Manager, issued this appeal to the wider community: “The next step will most likely involve the implementation of a wireless network of environmental sensors, spread across a European city. Despite the breadth of the existing consortium, we are very interested in talking to other institutions, be they national or international, about the hosting of the final EMMON demonstrator. This hosting could include playing the role of end-users for this technology. One attraction would be the leave-behind potential of the demonstrator”.

This 36 month R&D project (www.artemis-emmon.eu) is jointly funded by the 7th Framework Programme of the European Union, the ARTEMIS JU and the Member States. The consortium comprises nine European partners. There are three Universities (Instituto Superior de Engenharia do Porto of the Polytechnic Institute of Porto, Portugal; Trinity College Dublin, Ireland and Aristotle University of Thessaloniki, Greece), a Research & Development Institute (Centro de Estudios e Investigaciones Técnicas de Gipuzkoa, Spain) and five representatives of Industry (Critical Software S.A., Portugal; Intesys Ltd and Critical Software Technologies Ltd, United Kingdom; SESM S.c.a.r.l., Italy and Akting Ingeniaritza S.L., Spain).

Researchers use Wi-Fi network to monitor melting glaciers

Scientists at two UK universities are planning to use Wi-Fi based network to monitor the flow of glaciers at the edge of the Greenland Ice Sheet.

The sensor network consisting of Global Navigation Satellite System (GNSS) receivers and Wi-Fi based relaying nodes will be installed on Helheim Glacier, an important calving glacier in south-east Greenland and will measure changes in the distribution of glacier motion and geometry.

The aim of the project is to improve understanding of how the outlet glaciers at the edge of the Greenland Ice Sheet, thought to be particularly sensitive to changes in air and ocean temperatures, react to climate change. The processes leading to iceberg formation or ‘calving’ are particularly important because they control mass loss from the ice sheet but are poorly understood.

Detailed observations of iceberg calving events have until now proved elusive due to the difficulty of positioning instrumentation on the heavily-crevassed ice surface and for the reason that sensors would be lost during iceberg calving. To combat this problem, researchers at Swansea and Newcastle Universities have joined forces to create a network of expendable GPS based receivers.

According to Dr Stuart Edwards from Newcastle University’s Geomatics Group and a graduate of Swansea University, software they have developed in Newcastle will allow the GNSS receivers to provide measurements accurate to a few centimetres.

According to Professor Tim O’Farrell from Swansea University’s College of Engineering, these sensors will be connected to each other and to a base station via a network of expendable, low-power wireless transceivers and deployed on the Helheim Glacier. A proportion of the network’s nodes are expected to be lost during each calving event. However, the novel ‘self-organizing” design of the network ensures that data can still be collected from the nodes that remain operational.

The innovative nature of the network and its components make it economically and logistically possible to deploy a large number of sensors by a helicopter in the heavily crevassed calving region of the glacier.

In addition, the use of wireless networks in an extreme environment will assist in the development of the next generation of wireless networks such as mobile phone networks.

The research project will be undertaken during two summer field seasons in 2012 and 2013.

Researchers unveil first mm-scale computing system

University of Michigan computer scientists and engineers are at the International Solid-State Circuits Conference in San Francisco today presenting papers on two systems: a prototype implantable eye pressure monitor for glaucoma patients and a compact radio for wireless sensor networks.

What makes their presentation so remarkable is that both systems involve what is believed to be the first complete millimeter-scale computing system.

The near-invisible package is just over 1 cubic millimeter in size and includes an ultra-low-power microprocessor, a thin-film battery, a solar cell, memory, a pressure sensor, and a wireless radio with an antenna.

“Millimeter-scale systems…have a host of new applications for monitoring our bodies, our environment, and our buildings,” said Professor David Blaauw in a news release. “Because they’re so small, you could manufacture hundreds of thousands on one wafer. There could be 10s to 100s of them per person, and it’s this per capita increase that fuels the semiconductor industry’s growth.”

The team points to Bell’s Law, formulated by computer engineer Gordon Bell in 1972, which says that a new class of smaller and cheaper computers is developed roughly every decade. This is considered to be a partial corollary to Moore’s Law, established in 1970 and named after Intel co-founder Gordon Moore (first names coincidental), which describes the now 50-plus-year trend that the number of transistors able to be placed on an integrated circuit doubles every two years.

The new system out of Michigan is being hailed as the first in a new class of millimeter-scale computing, and while the researchers are specifically targeting the medical side of body sensor networks, other potential applications include tracking such things as pollution, weapons, structural integrity, and more.

The eye pressure monitor is designed not only for direct implantation but also continuous tracking of glaucoma, a disease that can lead to blindness. It incorporates the team’s third-gen Phoenix Processor, which combines an extreme sleep mode and a unique power-gating system for ultra-low-power usage (averaging 5.3 nanowatts).

The system wakes every 15 minutes to take measurements and relies on 10 hours of indoor light or 1.5 hours of sunlight every day for full battery recharging. The team says the device could be commercially available in the next several years.

The researchers are also working on a radio with an on-chip antenna using an advanced complementary metal-oxide-semiconductor (CMOS) process that allows them to control the antenna’s shape and size, and thus its response to electrical signals. Because of this control, they can do away with the bulky external crystals that keep time and select radio frequency bands for communication between two isolated devices, thereby drastically reducing the size of the radio system.

The university hopes to patent these tiny-yet-huge developments, and is looking for commercial partners to help bring the tech to market.
