Excerpt
Excerpt: The NIST Smart Space project. The NIST Smart Space Laboratory has been created to offer assistance to industrial research and product development laboratories as to face the numerous performance and interoperability challenges inherent in the Smart Work Spaces of the future. We believe that the shift to Pervasive Computing is already well under way and will have as much impact on industry, and daily life as personal computing did. Our Modular Test Bed is designed to allow our industrial and academic laboratories to bring their technologies together for integration and performance testing needed. Pervasive Computing refers to the trend to numerous, easily accessible computing devices connected to each other and to a ubiquitous network infrastructure. This will create new opportunities and challenges for IT companies as they place computers and sensors in devices, appliances, and equipment in buildings, homes, workplaces, and factories. Within a few years, embedded devices able to execute complex software?
