Computing in the WildThe natural world is not computer-friendly. To function outdoors and in industrial settings, computers must be "hardened" with enclosures to protect the electronics from weather, soil, wild animals, and jolts. But sensors must be exposed to the environmental conditions they monitor. (1) Motes have small, inexpensive shells and (2) use redundancy to increase their reliability. They are designed to be (3) inexpensive enough for deployment in large numbers to gather very detailed information about the environment. Networks of them are dense enough that it is acceptable if some fractions die and smart enough that the overall system can (4) adapt to the loss and keep working. Designing for loss and the uncertainty of the physical world presents new challenges but allows perceptive networks to be economical, portable and unobtrusive.
While designing successive generations of motes and their networking capability, we have conducted pilot projects to help identify how the technology needs to evolve to be most useful for various applications.

Under the intense conditions of the early universe, ionized matter gave off radiation that was trapped within it like light in a dense fog. But as the universe expanded and cooled, electrons and protons came together to form neutral atoms, and matter lost its ability to ensnare light. Today, some 14 billion years later, the photons from that great release of radiation form the cosmic microwave background (CMB). Tune a television set between channels, and about I percent of the static you see on the screen is from the CMB.
