New wireless sensor network keeps tabs on the environment
June 05, 2008Have you ever wondered what happens in the rainforest when no one is looking?
Research in the University of Alberta's Faculty of Science may soon be able to answer that question. The departments of computing science and earth and atmospheric science have been working together to create a Wireless Sensor Network that allows for the clandestine data collection of environmental factors in remote locations and its monitoring from anywhere in the world where the Internet is available.
The research team, including Pawel Gburzynski, Mario Nascimento, and Arturo Sanchez-Azofeifa, recently launched EcoNet, a functional model of a WSN for environmental monitoring in the display house in the University of Alberta's Agriculture/Forestry Centre. The display house hosts a small but feature-rich environment that mimics that of a tropical forest. Using a WSN, a number of sensors can continuously monitor factors like temperature and luminosity and will process, store and transmit data co-operatively and wirelessly with other sensors to generate data that can then be collected and made available to users virtually anywhere on the globe. The sensors represent a technology for researchers to monitor diverse phenomena continuously and inconspicuously.
Having the data continuously monitored by researchers substantially increases the chances of uncovering anomalies early enough to investigate them promptly and thoroughly.
The overall framework of WSN can also be extended for use in other closely related scenarios such as monitoring potentially dangerous situations like hazardous waste disposal, or hard-to-witness phenomena such as ice cap movements in the Arctic.
The opportunities these sensors will provide to scientists are paramount in a global environment that is changing at an ever-increasing pace.
Once the display-house prototype is tested and customized, at least two sites are to be fully deployed in the fall, one likely in the Brazilian rainforest, and the other in a forest in Panama.

University of Houston research team aims to help caregivers monitor patients' health and whereabouts
For those who are caring for elderly parents, peace of mind is hard to come by. And, for their parents, dignity is hard to retain. But a team of University of Houston researchers hopes to ease worries and frustrations by designing an affordable in-home health-monitoring system that will notify caregivers, via smartphones or PDAs, if their loved ones need attention.
Rainforest rehab in every sense
Sophisticated sensors that measure leaf wetness, soil moisture and temperature are helping rehabilitate rainforest in the Springbrook World Heritage precinct in south-east Queensland.
Bridging the gap between wireless sensor networks and the scientists who use them
A new, simpler programming language for wireless sensor networks is designed for easy use by geologists who might use them to monitor volcanoes and biologists who rely on them to understand birds' nesting behaviors, for example. Researchers at the University of Michigan and Northwestern University have written the language with the novice programmer in mind.

Maximum Comfort for Patients
A multiple-parameter medical network with wireless sensors for the measurement of vital body functions will be exhibited by Fraunhofer Institute for Integrated Circuits IIS at the CeBIT 2004. It is comfortable and convenient to wear - the wireless sensor wristband of Fraunhofer IIS for the measurement of the pulse waves and the oxygen saturation of the blood. It is part of a multiple-parameter network for the mobile monitoring of vital body functions. It finds application with medical supplies and equipment manufacturers, hospitals and home-care services. The multiple-parameter network comprises together with the Pulse Oximeter, to be seen at the CeBIT show, three other sensor components: a

RoI of wireless sensor networks by Aravind Mohanoor I am creating this blog to discuss principles from economics as they apply to wireless sensor networks(WSN). I am also hoping to stimulate discussion about some WSN topics which I have been interested in, and hoping that this blog will establish a forum for researchers with similar interests and/or for people with useful information to share about WSNs. Kindle blogs are fully downloaded onto your Kindle so you can read them even when you're not wirelessly connected. And unlike RSS readers which often only provide headlines, blogs on Kindle give you full text content and images, and are updated wirelessly throughout the day. |
