Sensors Everywhere
It's not the first time i choose to tell you about wireless sensor-network technology (check below for previous references). But this article from InformationWeek gives me the opportunity to revisit the subject. The story describes several current projects, from the Department of Homeland Security that wants to secure the U.S. borders, to British Petroleum (BP) monitoring its plants and chips. Hewlett-Packard and Intel also are experimenting with wireless networked sensors in some warehouses and factories.

As the market is growing, research companies are trying to figure its size. For example, Harbor Research says that the number of wireless sensors in use will grow from 200,000 today to 100 million in three years, adding that this will be a $1 billion market by 2009. I don't know if these numbers will be reached, but it's true that wireless sensor-networks, especially mesh networks, are really attractive because of their low costs of deployment.

Please read the original article if you have time or this summary for selected excerpts and comments about some remaining software challenges.
