Atific Helicopter: A Multi-Radio WSN Development Kit

AtificAtific, a finnish company, introduces the world’s first multi-radio platform for WSN.
The platform contains high performance embedded platform based on a FPGA chip, which can host several embedded processors in addition to traditional programmable HW logics. Besides, it uses 1 to 4 separate and independent digital radio modules and supports mesh networks.

It excels as a platform for heterogeneous protocol and application software and hardware development. The kit comes with a reference design, documentation, white paper with examples and source codes. See special prices for universities and product details here.

Nictor, making waves in wireless enabled studies on irrigation

The wireless sensor device looks like a toy and is not much bigger than a person’s hand — yet it heralds a revolution that could save massive amounts of water and help keep the state’s agriculture industry afloat. The device, called a “nictor”, uses wireless sensor devices that have been developed in a laboratory at the University of Melbourne. The lab is part of the National ICT Australia group of research centres.

The wireless technology is at the heart of a system that gets water to the crop and farm on demand, not by a scheduled roster. The system uses water more efficiently than a conventional irrigation system and requires less water to be used. It’s the result of research that has been driven by John Langford, director of the university’s Melbourne Water Research Centre, and a team of specialists from various organisations.

CitySense

BBN Technologies, Harvard University, and the City of Cambridge are collaborating on a wireless sensor network that spans, Cambridge, MA, but will provide access for educational institutions, from kindergartens to graduate schools, all across the U.S.

Funded by the National Science Foundation, the network will consist of 100 streetlight-mounted sensor nodes, each equipped with a professional meteorological sensor package for environmental monitoring. The sensors will detect weather measurements, such as wind speed, direction, temperature, air pressure, relative humidity, and rainfall. Radios in the nodes will allow them to communicate across a mesh-network. Through a gateway to the Internet, all data collected will be freely available to academic researchers throughout the U. S. The network will also be an open resource for the sensor network community, giving them the opportunity to test new algorithms for distributed sensor data processing and wireless networking in a real-world environment.

The Long Tail of Mobility

In his book on changing economics of web commerce, The Long Tail, Chris Anderson illustrates how the Internet is changing the laws of distribution from digital products from entertainment (movies and CDs) to manufactured products
Wireless networks are, too, growing a long tail, as billions, maybe even, trillions, of devices are being connected to an increasing pervasive and integrated array of wireless networks powering the mobility generation.

The interesting story about Maria Feng, a UCI researcher who develops vibration sensors that monitor the health of everything from bridges to dams is available on OCRegister blog, here.

Environmental Sensor Networks:A revolution in the earth system science?

An interesting paper on Sensor Networks for Environmental applications has been published on Earth-Science Reviews. The abstract states:
“Environmental Sensor Networks (ESNs) facilitate the study of fundamental processes and the development of hazard response
systems. They have evolved from passive logging systems that require manual downloading, into ‘intelligent’ sensor networks that
comprise a network of automatic sensor nodes and communications systems which actively communicate their data to a Sensor
Network Server (SNS) where these data can be integrated with other environmental datasets. The sensor nodes can be fixed or
mobile and range in scale appropriate to the environment being sensed. ESNs range in scale and function and we have reviewed
over 50 representative examples. Large Scale Single Function Networks tend to use large single purpose nodes to cover a wide
geographical area. Localised Multifunction Sensor Networks typically monitor a small area in more detail, often with wireless adhoc
systems. Biosensor Networks use emerging biotechnologies to monitor environmental processes as well as developing proxies for immediate use. In the future, sensor networks will integrate these three elements (Heterogeneous Sensor Networks). The communications system and data storage and integration (cyberinfrastructure) aspects of ESNs are discussed, along with current challenges which need to be addressed. We argue that Environmental Sensor Networks will become a standard research tool for future Earth System and Environmental Science. Not only do they provide a ‘virtual’ connection with the environment, they allow new field and conceptual approaches to the study of environmental processes to be developed. We suggest that although technological advances have facilitated these changes, it is vital that Earth Systems and Environmental Scientists utilise them.”

Underwater Wireless Modem

Wireless Fibre Systems has unveiled the S1510, an Underwater Radio Modem that can be used at depths to 33 feet. The modem can be used to help divers, boats, submarines and underwater sensors communicate. From the developers website:

WFS is a pioneer in the use of Radio Frequency (RF) technology for underwater applications. Traditional sonar techniques offer limited bandwidth and can be problematic in noisy or multi-path environments. RF technology can provide an attractive alternative. WFS is developing solutions that are immune to acoustic noise. These include a low data rate, long range, subsea radio telemetry solution and high bandwidth “non-contact” data links suitable for high speed communications and uploads from Autonomous Underwater Vehicles (AUVs). This technology also offers capability for underwater navigation, remote sensing and detection.
