We believe that a middleware service infrastructure can greatly simplify the tasks of creating context-aware applications and maintaining the suite of sensors that supports these applications. By providing a uniform layer of abstraction and a common programming model, such an infrastructure would provide support for context-aware applications in a platform neutral manner. Furthermore, such an infrastructure would be “always on,” allowing sensors and devices to be deployed incrementally without having to update every application or having to restart the entire system.
