Smart Dust - Tiny Computer Stuff

Smart Dust - Tiny Computer Stuff

Twenty-four hours a day, year after year-out, Flemming medical oxygen to the heart and the blood of a patient who works in a factory at minimal cost in real time. Researcher Galvin got the role of monitoring in real-time two dozen variables in a very hostile environment around the clock over large areas in all three dimensions. This hostile environment is a battlefield scenario or uninhabited glaciers in the Himalayas. There are many complex problems such thorny, given the chance that researchers will continue investigating. The endless series of problems such as ecosystems, habitats for animals / birds, soil biodiversity, nutrient cycles, climatology, flooding, traffic, pollution and the like.

We can not use the limited data to solve complex problems. For illustration purposes, the soil is the most complex in the ecosystem of the layer, but it is difficult to use, because the selectivity of the sample in the laboratory analytical techniques to understand the data collected is limited. To monitor whether there is such a global phenomenon of the method? The efforts of our scientists, the solution is at hand. Today, small computer packed in a box size of several millimeters called "promotes" or "smart dust". They are capable of continuous real-time data from the natural world on a large scale to follow a large population sample in large geography. Some call it promotes small stuff ", others call it smart dust". Motes fact the building blocks of wireless sensors. Why "smart dust", the name was invented by smart dust Pister, University of California at Berkeley describe their own version of the sensors were integrated into the network in 1000, or even millions to a natural scenario to understand that these respected as a human brain .

The core of a splinter is a small low power low cost computer. A Typical Mote uses an 8-bit micro-computer with 512 Kbytes of flash memory onboard running at 4 MHz. CPU matches usually CPU IBM 8088 PC with 10-bit A to D converter. It is designed to consume only 8 mg amp work in micro-amp and 15 during sleep. It may Operation Life for nearly 150 hours on two AA batteries. To consume, but it is done in 10 seconds to sleep and wake up and give the status of a few micro-seconds before you sleep again. A programmer writes software for the remote and make it perform a certain way. Design, development and deployment, including network discovery, control, guidance, information processing, queries, and security, create web sensors for scientific applications require a substantial adjustment, the new standards, a dedicated operating system, programming and user-friendly web tools. To reduce costs, to look at the commercial adoption and network on a wider basis, which is a slower speed on a couple of years.
