A programmable structure for pervasive computing

摘要

This work presents the idea of a proactive and extensible pervasive computing infrastructure. It supports its users by filtering and pushing highly personalized context-aware information. We have derived a general structure that describes a virtual computer extensible at run-time by user-defined information filters. Individual users may program the structure using an expressive event-based filter programming model. In addition, the structure implements general design principles of push-based communication, by supporting both server-level and application-level extensibility.
