COSMOS : composition de noeuds de contexte. Denis Conan, Romain Rouvoy and Lionel Seinturier. Techniques et Sciences Informatiques, 27(9-10):1189-1224, 2008.

Abstract

Ubiquitous applications are facing a large diversity ofexecution contexts. However, this diversity requires some continualadaptation to preserve the correct execution of these applications.Consequently, the observation of the execution context plays animportant role. Even if ``user-centered and ``system approacheshave proven their relevance in this domain, they suffer from somelimitations when expressing the composition of inferences and whenconsidering the scalability issue. Therefore, we propose to reorganisethe classical functionalities of a context manager to systematicallyintroduce cycles ``collect / interpretation / identification ofsituations''. This approach is based on the definition of the conceptof context nodes composed in a graph (hierarchy with sharing), and themapping of the concept into components and software architecture foreasing the definition and the management of context managementpolicies. Our proposition, named COSMOS, is detailed and thenevaluated with the example of the composition of context informationfrom system resources.
