Software Adds Smarts to Sensor Nets
A University of California at Berkeley team responsible for the TinyOS embedded operating system has formed a company to provide software intelligence to ZigBee and other wireless sensor networks. Arch Rock Corp.'s Primer Pack environment builds on middleware work done at Berkeley on three generations of "motes"--sensor nodes designed into meshes that use TinyOS 2 for self-discovery and monitoring. The work also included a dedicated database called TinyDB, used in making sensor information available through Web services via an application-layer language like the Extensible Markup Language.
