Context-Aware Service Composition in Pervasive Computing Environments [chapter]

Sonia Ben Mokhtar, Damien Fournier, Nikolaos Georgantas, Valérie Issarny
2006 Lecture Notes in Computer Science  
In this paper, we present an approach to the dynamic, context-aware composition of services to perform user tasks, i.e., software applications abstractly described on the user's handheld device.  ...  A major challenge in pervasive computing environments is to provide users with complex, context-sensitive applications, dynamically composed from networked services.  ...  "Context-awareness is a property of a system that uses context to provide relevant information and/or services to the user, where relevancy depends on the user's task."  ...
